Know Rabies ,Dr. Sharda Jain, Dr. Rashmi Jain, Dr. Jyoti Agarwal
Rabies is a 100% fatal viral disease transmitted through animal bites or scratches, especially from dogs. India reports the highest number of rabies deaths globally, with approximately 20,000 deaths per year. Children under 15 years old are at the highest risk, accounting for about 50% of rabies exposures. It is essential to complete the full five-dose vaccination course to prevent rabies, as incomplete vaccination leads to 10% of annual rabies deaths in India. Rabies can be transmitted through scratches with or without bleeding, not just bites. Home remedies cannot prevent rabies after an exposure - only full post-exposure prophylaxis including wound washing, vaccination, and rabies immunoglobulin if needed can protect against
Avian power
Avian flu can spread from birds to humans through contact with infected bird droppings or pigs. Symptoms in birds include appearing weak and reduced egg production, while human symptoms mimic the flu. Two major outbreaks of the H5N1 avian flu strain occurred in Hong Kong in 1997 and multiple countries in 2006, resulting in many human deaths. During these outbreaks, millions of chickens were culled to control the spread and human cases were linked to contact with infected poultry or wild birds.

Malaria by francheska camilo
Malaria is caused by parasites transmitted through mosquito bites. It affects over 200 million people annually and causes over 1 million deaths. Biotechnology research is working to develop new treatments, such as vaccines and drugs targeting different stages of the parasite's lifecycle. Detection of malaria has also advanced through new diagnostic tests identifying parasite biomarkers using techniques like monoclonal antibodies and real-time PCR. While progress has been made, drug resistance remains a major challenge, and continued biotechnology research is needed to control and eliminate malaria worldwide.
Press Releases
This document contains press releases from three different studies:
1. A study finding that a bacterial molecule can train the immune system to tolerate infection without causing illness. This was reported by multiple news sources.
2. A study identifying anti-infective compounds from bacteria that could interrupt acute and persistent infections. This led to the founding of Spero Therapeutics.
3. A study identifying factors that can predict risk of multiple infections in patients with severe burns. This was also reported by multiple medical and science news organizations.

Malaria is a serious global health issue caused by parasites transmitted via mosquito bites. It is responsible for millions of deaths each year, especially among young children. While some drug treatments exist, development of new medicines has been lacking. However, a recently patented treatment using colloidal silver has shown promise in resolving malaria symptoms within five days. This over-the-counter formulation could provide an affordable and accessible option for those at risk of contracting malaria.
Eradication of human African trypanosomiasis? Don't forget the pigs!
- Human African Trypanosomiasis (HAT) is a neglected tropical disease spread by tsetse flies in sub-Saharan Africa, with the goal of eliminating cases by 2020 and eradicating transmission by 2030.
- Pigs are an important livestock for smallholder farmers in Uganda and can be infected by the same Trypanosoma species as humans, posing a potential reservoir risk for HAT transmission.
- More research is needed to understand the role of pigs and other livestock in the epidemiology of HAT, including monitoring Trypanosoma infections and vector host preferences in pig keeping communities.

Deadly H5N1 birdflu needs just five mutations to spread easily in people
Reference: Phys.org. 15 Apr 2014. Dutch researchers have found that the virus needs only five favorable gene mutations to become transmissible through coughing or sneezing, like regular flu viruses.
World health officials have long feared that the H5N1 virus will someday evolve a knack for airborne transmission, setting off a devastating pandemic. While the new study suggests the mutations needed are relatively few, it remains unclear whether they're likely to happen outside the laboratory.
A Worldwide pandemic-- the source? Man-made

This study used geo-information techniques to map the spatial incidence of malaria in Calabar South Local Government Area of Nigeria. The researchers identified potential mosquito breeding environments and established a relationship between residential distance, malaria incidence, and breeding locations by creating a malaria risk map. The results showed that closer distance to breeding points correlated with higher malaria incidence, and farther distance correlated with lower incidence. It is recommended that more research be done to find more effective solutions.

The black death_bubonic_plague_2
The document summarizes how the bubonic plague, also known as the Black Death, spread from rats to humans in the 14th century. It was carried by fleas that fed on infected rats and then bit humans, transmitting the bacteria. The Mongolians used infected bodies to help take the walled city of Kafa. Symptoms included swollen lymph nodes, fever, chills and vomiting blood. People fled affected areas but continued spreading the disease as they traveled to Europe and England. The plague eventually stopped spreading as all the rats died and fewer people were getting infected.
Malaria presentation
Malaria is a life-threatening disease transmitted through mosquito bites. It is caused by Plasmodium parasites and infects around 3.3 billion people worldwide each year. Common symptoms include fever, shaking chills, flu-like illness, and anemia. It is diagnosed through blood tests and treated with antimalarial drugs. Prevention methods focus on eliminating mosquitoes and limiting exposure through bed nets and insecticides. Despite efforts, malaria remains a significant global health problem, especially in parts of Africa, Asia, and South America.
DeDengue fever
Dengue fever is caused by viruses transmitted through mosquito bites. The virus infects mosquitoes which then transmit the virus to humans during blood feeding. Common symptoms include high fever, headaches, muscle and joint pains. While there is no specific treatment, rest and fluid intake can help reduce fever. Preventive measures include wearing protective clothing, using mosquito nets, and removing stagnant water to prevent mosquito breeding.
Psychological Affects Of Media Sensationalism Of Public Health Issues
This document analyzes the psychological effects of media sensationalism of public health issues. It hypothesizes that media sensationalism is more harmful than beneficial. Methods include literature review of SARS, H1N1, and influenza outbreaks. Results show media coverage led to unfounded fear and panic, increased health industry profits, and reduced doctor visits and vaccinations, increasing disease risk. The discussion notes limitations but suggests educating the public on sensationalism and its impacts.
MALARIA
Malaria is caused by a parasite transmitted through mosquito bites. When the parasite enters the bloodstream, it travels to the liver and then infects red blood cells. The parasites multiply within the cells, causing them to burst and release more parasites. This cycle causes symptoms like fever and chills that occur every two to three days. There are four types of malaria parasites that can infect humans, with one type in particular causing a more severe form of the disease. Preventive measures include medications, insect repellent, limiting outdoor activities at dusk/dawn, and sleeping under bed nets. A blood test can detect the parasite and treatment is available to cure the illness if diagnosed early.
West nile virus slides
West Nile virus is an arbovirus spread by infected mosquitoes that can cause febrile illness, encephalitis, or meningitis. It was first identified in Africa in 1937 and outbreaks occurred in Algeria in 1994 and Romania in 1996. The first case in the United States was detected in New York City in 1999, after which it spread across the continental US, into Canada, and parts of the Caribbean and Latin America over the next 5 years.
Outbreak of High Patogen Avian Influenza H5N8 in Germany
Germany has reported an outbreak of highly pathogenic avian influenza, H5N8 in fattening turkeys in North East Germany
(Mecklenburg - Western Pomerania). Increased mortality was observed in one of the six sheds of 15 week old birds for fattening (total number of turkeys on the premises ~ 31,000 of which each shed contained 5,000).
Comparative Study on Vaccination In Akkalkuwa BY IMRAN HUSAIN
This document presents the results of a comparative study on vaccination in Akkalkuwa, India. The study collected data from 76 children ages 3 months to 10 years from a residential campus. The results found that 80% of people had completed vaccination, with over 70% receiving all routine vaccines except the vitamin A booster. However, some people avoided vaccination due to costs, unavailability of experts or vaccines, past side effects, or lack of awareness. The study concluded that improving access to affordable and expert vaccination in government hospitals could boost child health and reduce costs.

In it's current form it has been around since 1997 and although thy virus types have changed, emergency response, management & control are still a hot issue. In this article published in 2006 in the US magazine Poultry Perspectives, the subject what to do during crisis situations is presented. The conclusions are still valid today and may help to prevent large-scale outbreaks
Dossier transmission: Transmission of Avian Influenza Virus to Dogs
This document reports on the transmission of an avian influenza virus (H3N2) to dogs in South Korea. Several dogs exhibited severe respiratory disease and three genetically similar canine influenza virus strains were isolated. Experimental infection of beagles demonstrated that the virus could be transmitted between dogs and cause clinical signs like fever and lung lesions. The canine respiratory tract was found to contain receptors for binding avian influenza viruses, suggesting potential for direct transmission from poultry. This provides evidence that dogs may play a role in interspecies transmission of influenza viruses.
Modelling wind-borne spread of HPAI between farms (2012)
To understand the risks of spreading contaminated materials caused by stable gassing, a quantitative understanding of the spread of contaminated farm dust between locations is a prerequisite for obtaining much-needed insight into one of the possible mechanisms of disease spread between farms.
The researchers Amos Ssematimba, Thomas J. Hagenaars, Mart C. M. de Jong of the Dutch Department of Epidemiology, Crisis Organization and Diagnostics, Central Veterinary Institute (CVI) part of Wageningen University and Research Centre, Lelystad, The Netherlands, and Quantitative Veterinary Epidemiology, Department of Animal Sciences, Wageningen University, Wageningen, The Netherland developed a model to calculate the quantity of contaminated farm-dust particles deposited at various locations downwind of a source farm and apply the model to assess the possible contribution of the wind-borne route to the transmission of Highly Pathogenic Avian Influenza virus (HPAI) during the 2003 epidemic in the Netherlands.
The model is obtained from a Gaussian Plume Model by incorporating the dust deposition process, pathogen decay, and a model for the infection process on exposed farms.
Using poultry- and avian influenza-specific parameter values we calculate the distance-dependent probability of between-farm transmission by this route.
A comparison between the transmission risk pattern predicted by the model and the pattern observed during the 2003 epidemic reveals that the wind-borne route alone is insufficient to explain the observations although it could contribute substantially to the spread over short distance ranges, for example, explaining 24% of the transmission over distances up to 25 km.

1. The document summarizes the origin and spread of the Zika virus from its discovery in 1947 in Uganda through recent epidemics. It was initially discovered accidentally while scientists were studying the yellow fever virus in monkeys. It then spread slowly through Africa and Asia with few reported human cases. Recent outbreaks in French Polynesia in 2013 and Brazil in 2015 caused worldwide concern due to links to birth defects. The rapid spread in the Americas was likely facilitated by large international events in Brazil that allowed transmission between populations.

The document discusses the SureDuz Mosquito Candle, a product that aims to eliminate mosquitoes and protect against malaria. It uses a proven mosquito eliminator instead of citronella and can burn effectively for 52 hours. Malaria is caused by parasites transmitted through mosquito bites and is still endemic in 99 countries, infecting 250 million people annually and causing nearly one million deaths.
West Nile For PECs
The West Nile virus originated in Uganda in 1937 and has since spread throughout Africa, Europe, the Middle East, and Asia, reaching the United States in 1999. It is transmitted primarily between birds via mosquitoes, and can infect humans, causing mild to severe illness. Older adults over 50 are most at risk. While there is no vaccine, individuals can reduce risk of infection by using insect repellent, eliminating standing water where mosquitoes breed, and minimizing outdoor activity during dusk and dawn when mosquitoes are most active.
Infectious Disease
Infectious diseases are caused by microorganisms like bacteria, viruses, fungi and parasites that can be transmitted between individuals. They cause symptoms like fever, chills and body aches. Throughout history, scientists have made important discoveries to better understand and treat infectious diseases, such as Semmelweis identifying the importance of hand washing, Pasteur developing vaccinations, and Fleming discovering penicillin.

10_of_the_best Research Project_2014
Associate Professor Phillip Darcy has developed a novel approach to train white blood cells to better detect cancer cells by genetically modifying them to express chimeric antigen receptors that specifically recognize antigens on cancer cells. Testing in mouse models showed the modified white blood cells could effectively eradicate breast, sarcoma, and colon cancer cells without harming normal tissues. A phase I clinical trial is underway at Peter MacCallum Cancer Centre, with initial results showing the modified cells persisting for up to 10 months and homing in on cancer sites to mediate anti-tumor activity with no safety issues. This research aims to develop a new cancer therapy with few side effects compared to conventional treatments like chemotherapy and radiation.

Vaccines Safety and Effectiveness
Do you think vaccination is an important or just harmful substance forced by pharmaceutical companies cooperating with the governments to inject into people? Vaccine can be defined as “biological preparations that, when introduced into the body, cause an individual to acquire immunity to a specific disease” (Davidson. 7). So, for decades, vaccines have been considered one of the best revaluation in medical practice. A long time ago, people all around the world tried to fight with different kinds of fatal diseases by different ways, and one of the most Significant ways is to make a vaccine, to prevent such life- threatening diseases. The first vaccine was against the Smallpox disease. Smallpox is a highly contagious disease and caused a lot of fatalities all around the world, and it is transmitted between people by inhalation of droplets of virus or direct contact with smallpox lesion secretions (Davidson 25). It is a deadly disease, it caused blindness and permanent scars in the patients that survived. Finally, after several attempts to make a vaccine for Smallpox, Edward succeeded to produce an effective and safe vaccine in 1796 by using the cowpox vaccine to protect from smallpox. Cowpox is a disease cause by cows and transferred to human, and Jenner’s theory was based that whoever had cowpox will be immunized against smallpox (Davidson 29). “Edward Jenner was an English country doctor who introduced the vaccine for smallpox. Previously a keen practitioner of smallpox inoculation.”
Then, century after century, vaccine after vaccine was developed for different kinds of diseases. In the 20th century, one of the most known vaccines was Diphtheria and Tetanus vaccines. Diphtheria is a respiratory illness, causing the release of exotoxin from Corynebacterium diphtheriae bacteria which leads to death of mucus cells in the throat, mouth and nose, and as a result of cells accumulation the pseudo-membrane are build up and block the airways of the patients which causes death (Davidson 42) After years of experiments and trials to make a vaccine to fight this disease, Gaston Ramon a French veterinarian and biologist who realized that attenuated Diphtheria toxin is able to activate the immune system of people without causing serious side effects, and by 1927, the toxoid vaccine was freely used all around the world, and it succeeds to drop the number of cases of diphtheria. Then, by using the same way of toxoid, combined Diphtheria and Tetanus Toxoid vaccines were produced. Tetanus can be described as a nerves system infection that leads to spasm and contract of body muscles, especially jaw muscles which make the patients unable to open their mouths (Davidson. 44)
Another example of one of the most significant vaccine is a Polio vaccine. Polio disease, mainly affecting children under 5 years old, and leading to paralysis and often to death due to immobilization of respi.

AIDS/ HIV in Health Education
The document discusses AIDS/HIV and its impact on global health. It defines AIDS as being caused by HIV, which damages the immune system. Over 130 million adults and 10 million children worldwide had been afflicted with AIDS as of 1993. No treatment has been discovered yet, but preventive measures like safe sex practices and blood screening can help limit transmission. The virus spreads primarily through unprotected sex and contact with infected blood or bodily fluids. Research is ongoing to develop effective treatments and vaccines against HIV/AIDS.

The Catalyst November Edition
This document discusses efforts to eliminate mosquito populations in the South Pacific using bacterial infection. Scientists in French Polynesia developed a strategy to infect mosquito larvae with the Wolbachia strain of bacteria, which is harmful to the invasive Aedes polynesiensis mosquito species. The infected male mosquitoes are then released, as their offspring with wild females will not survive. This method has already shown success in isolated South Pacific islands, eliminating mosquito-borne diseases. The implications are that this novel approach could provide an effective, non-chemical means of controlling mosquito-borne illness around the world.
Flu Season
What is it about this flu that gets everyone so uptight? There are natural ways to fight the flu, and almost any bug and disease out there!
Changing Pathogens
The document discusses antibiotic resistance and how it develops through natural selection. It explains that when antibiotics are used, only bacteria that are resistant to the antibiotic will survive and pass on the resistant genes. This can lead to epidemics if the bacteria become resistant to multiple antibiotics. The document also discusses the H5N1 bird flu virus and efforts to develop a vaccine against it.
Vaccines Letter
This document discusses vaccines and their importance. It begins by introducing the topic of vaccines and explains that there are many different types of vaccines that are important to receive yearly shots of. Vaccines can save lives through the medicines they contain by stimulating an immune response. The document then discusses several different types of vaccines in more detail, including live-virus vaccines, killed-virus vaccines, toxoids, and other types. It emphasizes that vaccines are administered by medical professionals to protect against diseases.

Question 3
2nd New Hampshire resident dies of Eastern Equine Encephalitis (EEE)
New Hampshire public health officials say a Manchester [Hillsborough County] resident is the 2nd person to die from eastern equine encephalitis (EEE) virus infection this season, summer and fall 2014. Public Health Director Dr. Jose Montero says the individual was exposed to the virus at the end of August and died in mid-September 2014. He says testing was complicated, and the virus was not confirmed until after the patient died. In the 1st fatal case, someone who became sick in the Conway, Carroll County, area in August died last month September 2014. A 3rd person also has been diagnosed with EEE, which is spread by the bite of infected mosquitoes and can lead to seizures and coma. Symptoms can include high fever, severe headache, stiff neck, and sore throat. These cases in New Hampshire are not surprising since they occurred within the geographical range of EEE virus in the eastern USA, where human and equine cases occur sporadically. As is usual, there are many more equine than human cases. There have been recent human cases in New Hampshire and an equine case involving a mule. The virus is maintained in passerine birds and transmitt ...
Co relation of csf and neurological findings in hiv positive patients
This document provides a literature review on neurological manifestations in HIV positive patients and the correlation with cerebrospinal fluid (CSF) parameters. It summarizes several studies that examined the prevalence and nature of neurological disorders in HIV patients and their relationship to CD4 count and other CSF markers. Many studies found neurological problems to be common and correlated with immunosuppression. Cryptococcal meningitis was a frequent opportunistic infection. Accurately diagnosing neurological conditions is important for treatment, and CSF analysis continues to be useful for this despite modern imaging technologies.
Understanding Vaccine Mandates
Vaccines have saved millions of lives by preventing diseases like polio, measles, and diphtheria. Vaccines work by exposing the immune system to weakened or killed pathogens to develop immunity without causing illness. Vaccines are extensively tested for safety and approved by the FDA before being available. When enough of a community is vaccinated through "herd immunity," even those who cannot receive vaccines are protected by not allowing diseases to spread. Maintaining high vaccination rates ensures these diseases do not return and protects future generations for whom many such diseases have no cure.
Ghap hiv aids_handbook
The document discusses HIV/AIDS, including its causes, characteristics, and modes of transmission. Key points include:
- HIV weakens the immune system, leaving the body vulnerable to opportunistic infections and cancers that can cause AIDS.
- Without treatment, most HIV-positive people will develop AIDS within 10-15 years. Effective antiretroviral treatment can prevent progression to AIDS.
- Common opportunistic infections associated with AIDS include Pneumocystis pneumonia, tuberculosis, and cancers like Kaposi's sarcoma.
FinalPaper_SD
This document discusses the history and process of vaccine development. It begins with a brief history of the smallpox vaccine developed by Edward Jenner in 1796. It then explains that vaccines work by introducing a weakened version of a virus into the body to allow the immune system to develop antibodies. The document details the typical steps to make vaccines, including growing viruses in cell cultures or embryos to mass produce cells. Specifically, it notes that some vaccines are grown in human embryo cell lines, which are derived from cells harvested from aborted fetuses. The document provides an overview of the debate around using human embryos for vaccine research.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
