Viruses are non-living particles that can only reproduce inside host cells. They are smaller than bacteria and contain genetic material surrounded by a protein coat. Viruses come in various shapes and sizes and cause diseases like influenza, measles, HIV/AIDS, and some cancers. Edward Jenner developed the first vaccine for smallpox using a related cowpox virus. Viruses are identified based on their morphology, genetic material, presence of an envelope, capsid shape, host cell, and more. They exist in nature as parasites and depend on host cells for reproduction through lysogenic or lytic cycles.

Ebola is transmitted through direct contact with body fluids like blood, and has an incubation period of 2 to 21 days. Symptoms start with fever and weakness and progress to internal and external bleeding. The virus replicates rapidly within host cells, destroying tissues and organs before being shed to infect new hosts.
Ebola
The document discusses Ebola virus, which causes Ebola virus disease (EVD) or Ebola hemorrhagic fever (EHF) in humans and other primates. It describes how Ebola virus was first discovered near the Ebola River in Africa. There are five species of Ebola virus that can cause disease in humans. The document outlines the symptoms of EVD, which include fever, sore throat, muscle pain and can progress to vomiting, diarrhea, bleeding, and decreased organ function. It also discusses the epidemiology, statistics, clinical observations, treatment and prevention of Ebola virus disease.
Ebola Virus Disease.docx
Ebola virus disease is a severe and often fatal illness in humans that is transmitted through contact with infected animals or humans. The average fatality rate is around 50% and symptoms include fever, fatigue, muscle pain and bleeding. There are five strains of Ebola virus, with the Zaire strain being the most deadly. Ebola spreads through direct contact with bodily fluids of infected individuals but is not airborne. While there is no licensed vaccine or treatment, supportive care such as rehydration can improve survival rates.

EBOLA
The document discusses Ebola virus disease (EVD), including what it is, how it is transmitted, signs and symptoms, treatment, and preventative measures. EVD is a severe and often fatal disease in humans caused by infection with one of five Ebola virus strains. It spreads through direct contact with body fluids of infected humans or animals. Symptoms include fever, fatigue, vomiting and diarrhea which can be bloody. While there is no licensed treatment, recovery is possible with rehydration and treatment of specific symptoms. Preventative measures include avoiding contact with infected individuals or contaminated surfaces and objects.
Ebd presentation
This document discusses Ebola virus disease, including its history, symptoms, transmission, treatment and recommendations for prevention. It notes that Ebola is a severe and often fatal disease caused by Ebola virus. Fruit bats are believed to be the natural reservoir, infecting non-human primates which can then transmit the virus to humans through contact with bodily fluids. Major outbreaks have occurred in Central and West Africa. There is no vaccine or cure, so treatment focuses on relieving symptoms while the body fights the infection. Strict isolation protocols and proper hygiene practices are necessary to prevent further transmission.
Ebola virus disease
The document provides an overview of Ebola virus disease (EVD), including its origins, transmission, signs and symptoms, diagnosis, treatment and recovery. Some key points:
- EVD first appeared in 1976 in simultaneous outbreaks in Sudan and Democratic Republic of Congo. The current 2014 outbreak in West Africa is the largest on record.
- The virus is transmitted through direct contact with body fluids of infected humans or animals. Early symptoms are nonspecific but progress to hemorrhagic fever, vomiting, diarrhea and organ failure.
- Diagnosis involves detecting the virus or antibodies in blood, with RT-PCR being the most sensitive test. There is no approved vaccine or treatment, so care is largely supportive
Myrie
Ebola virus disease is caused by infection with one of five Ebolaviruses. It begins with flu-like symptoms and progresses to vomiting, diarrhea and decreased liver/kidney function. Bleeding occurs in 40-50% of cases. The disease spreads through contact with infected wildlife like fruit bats or through human-to-human transmission via bodily fluids. There is no approved vaccine or treatment, with fatality rates between 50-90%. Ongoing research focuses on understanding transmission and developing treatments.

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).

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Artificial Intelligence Symposium (THAIS)

The Ebola Virus - Powerpoint Presentation
- 1. EBOLA VIRUS
- 2. INTRODUCTION - Ebola hemorrhagic fever: Named after a river in the Congo where it was first found - Often-fatal disease in humans and nonhuman primates (monkeys, gorillas, and chimpanzees) - Has appeared sporadically since its initial recognition in 1976 - Mortality rate can reach 90%
- 3. -Family: Filoviridae -Order: Mononegavirales -5 distinct sub-species -Cote d’Ivorie(Ivory Coast) ebolavirus -Reston ebolavirus -Sudan ebolavirus -Zaire ebloavirus -Bundibugyo ebolavirus - Characteristics of Filoviruses: - Filamentous form with a uniform diameter of approximately 80 nm but display great variation in length. - Nonsegmented negative-stranded RNA genome containing 7 structural and regulatory genes. FAMILY AND ORDER
- 4. WHERE IS EBOLA FOUND • Natural reservoir of the Ebola virus remains unknown. • Zoonotic (animal-borne) • Four of the 5 subtypes occur in an animal host native to Africa 1 occurs in Philippine monkeys . • Origination: Africa...The virus is not known to be native to other continents, such as North America.
- 5. SYMPTOMS
- 6. Incubation period is 2-21 days . Symptoms are :- Arthritic pain Backache (low-back pain) Chills Diarrhea Fatigue Fever Headache Malaise (general feeling of being unwell) Nausea Sore throat Vomiting EARLY SYMPTOMS
- 7. LATE SYMPTOMS Late symptoms include: • Bleeding from eyes, ears, and nose • Bleeding from the mouth and rectum (gastrointestinal bleeding) • Depression • Eye inflammation (conjunctivitis) • Genital swelling (labia and scrotum) • Increased feeling of pain in skin • Rash over the entire body that often contains blood (hemorrhagic) • Roof of mouth looks red • Seizures, coma, delirium As many as 90% of patients die from the disease. Patients usually die from shock rather than from blood loss.
- 8. HOW IT WORKS Threadlike Ebola virions bud from a cell. The Ebola virus disables a cell's tetherin protein. Tetherin: A human cellular protein which inhibits retrovirus infection by preventing the diffusion of virus particles after budding from infected cells
Editor's Notes
- What is Ebola?: According CDC, Ebola hemorrhagic fever is a deadly disease in both humans and nonhuman primates (monkeys and chimpanzees) caused by the Ebola virus; characterized by high fever and severe internal bleeding; can be spread from person to person; is largely limited to Africa. First found in the area of the Democratic Republic of the Congo, near the River Congo in 1976 mortality rate: 90%, that’s why is called deadly disease.
- Highest fatality Rate is found in the Zaire sub-species. The only reported cases in the U.S., Italy and England were all part of the Reston sub-species.
- Natural reservoir of Ebola Virus still unknown until now. Its Zoonotic all 4 of 5 subtypes an animal Host in Africa
- The virus itself stores its nucleic acid in the form of a +mRNA genome and serves as a means of delivery of that genome into cells it targets as an obligate parasite (Cannot live independently of the Host cell), and constitutes the infection. Once in the host's cell, the RNA strands undergo reverse transcription in the cytoplasm and are integrated into the host's genome, at which point the retroviral DNA is referred to as a provirus (A provirus is a virus genome that is integrated into the DNA of a host cell). It is difficult to detect the virus until it has infected the host.
