Coronaviruses can cause respiratory infections in humans and are named for their crown-like appearance under electron microscopy. Common human coronaviruses include HCoV-229E, HCoV-OC43, SARS-CoV, HCoV-NL63, HKU1, and MERS-CoV. In December 2019, a new coronavirus emerged in Wuhan, China causing pneumonia and was subsequently named 2019-nCoV. It is genetically similar to SARS-CoV and can be transmitted between animals and people through air droplets. Symptoms include fever, cough, breathing difficulties, and pneumonia.

Rhino virus,corona,enterovirus
Rhino virus, corona virus, and enterovirus are common causes of respiratory illness. Rhino virus is the main cause of the common cold and symptoms typically resolve within a week. Corona viruses can cause mild upper respiratory infections or more severe illness like SARS. Enteroviruses are transmitted through oral contact and cause a variety of respiratory symptoms from sore throat to pneumonia. Treatment is usually supportive and prevention focuses on hand hygiene and sanitation.
Pathogenesis of Adenoviruses

This document provides information about COVID-19 (coronavirus) including what coronaviruses are, the symptoms of COVID-19, how it spreads, demographic groups most at risk, global case numbers and locations, mortality rates by age and health, the importance of social distancing to reduce strain on healthcare systems, global efforts to develop treatments, and basic safety tips.
Rhinovirus
Rhinovirus is the most common cause of the common cold. It is a non-enveloped, positive sense RNA virus that primarily infects the upper respiratory tract. Rhinovirus infections are most frequent and widespread during fall and winter. Symptoms include runny nose, sore throat, coughing, sneezing, and body aches. While the common cold is usually self-limiting, complications can occasionally occur such as sinusitis, ear infections, or pneumonia. There is no vaccine or cure for the common cold. Treatment focuses on relieving symptoms through rest, hydration, analgesics, and in some cases decongestants.

CORONAVIRUS DISEASE (COVID-19)
Coronavirus Disease, officially named as COVID-19, started as an epidemic in a live animal market in Wuhan, China, and spread throughout the world at an alarming rate. It was declared a pandemic by WHO on 11th March, 2020. The virus causing the disease was initially named 2019 Novel Coronavirus (2019-nCoV), but later officially renamed by WHO as Severe Acute Respiratory Syndrome- Coronavirus 2 (SARS-CoV-2). This virus is related to SARS-CoV and MERS-CoV that caused epidemics in China and Saudi Arabia in 2002 and 2012, respectively. The virus primarily affects the lungs, and causes death in a small proportion of patients due to Acute Respiratory Distress Syndrome (ARDS). The data on this new disease is very early, and might change as new data emerges.

COVID-19
Coronavirus Disease (COVID-19) is caused by SARS-CoV-2 virus. It spreads mainly person to person and symptoms range from mild to severe illness which can lead to death. The document discusses COVID-19's structure, symptoms, transmission, diagnosis, treatment and prevention. Key facts provided include that only those sick or caring for the sick need masks; the virus is not human-made; and older individuals and those with pre-existing conditions are more vulnerable to severe illness.
11.corona virus
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face.
The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette (for example, by coughing into a flexed elbow).

Coronavirus Disease (COVID- 19)
Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that can be mild, such as some cases of the common cold, and others that can be lethal, such as SARS, MERS, and COVID-19. Symptoms in other species vary: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to prevent or treat human coronavirus infections.

Corona virus infection
This document provides information about coronaviruses and the 2019 novel coronavirus. It discusses that coronaviruses cause common colds in humans and infect the respiratory and gastrointestinal tracts. Four to five strains commonly infect humans, including SARS. The novel coronavirus was discovered in 2012 in the Middle East and has caused over 150 cases and 64 deaths globally. Clinical signs include flu-like symptoms and cough after one week. Prevention focuses on hand washing and avoiding those with coughs. Treatment involves oxygen therapy, specimen collection, empiric antibiotics, and monitoring for deterioration.
Human para influenza virus
Human Parainfluenza Virus (HPIV) is a common cause of respiratory infections, especially in children. There are 4 types of HPIV that can cause illnesses ranging from mild upper respiratory infections to severe croup. HPIV is an enveloped RNA virus that enters host cells and replicates through transcription and translation of viral proteins. Treatment focuses on managing symptoms like cough and stridor. Precautions like masks and handwashing are recommended to prevent transmission through respiratory droplets.
Coronavirus
The document discusses the 2019 novel coronavirus outbreak that originated in Wuhan, China in December 2019. It provides background information on coronaviruses, describing their structure, discovery, symptoms, and strains that infect humans. The outbreak has led to over 37,000 confirmed cases and 800 deaths as of early February 2020. The virus shares about 70% genetic similarity with SARS and is believed to have originated in bats. Prevention methods include proper handwashing, avoiding contact with infected people, and use of N95 masks. Indian pharmaceutical companies are supplying antiviral drugs to treat coronavirus infections if needed.

This information deck explains Coronavirus (COVID-19) pandemic in detail. This content deck can be used for giving detailed sessions on COVID-19 to the employees. In brief, the deck explains that Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered family of coronavirus. It is believed that coronavirus (COVID-19) emerged from a bat-borne virus.
The first-ever case of this deadly virus was detected in Wuhan, China, in December 2019. It is said to have spread through a wholesale food market in Wuhan, where humans must have contracted the disease after coming in contact with the infected bat's species. This highly contagious virus spreads from one (infected) person to another, and within six months, WHO announced the COVID-19 outbreak- a pandemic.
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop severe illness. The usual symptoms of this virus are fever, cough, breathing issues, body aches, and in some cases, other diseases accompany it. The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes. COVID-19 is a form of respiratory illness, and it gradually attacks the lungs if not taken immediate measures to control it. The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes, and how it spreads. To protect oneself from this infection, you must thoroughly wash your hands or use an alcohol-based rub frequently and not touch one's face. Always wear a face mask. By taking these strict measures, we can slowly but gradually control the spread of COVID-19.

The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes. COVID-19 is a form of respiratory illness, and it gradually attacks the lungs if not taken immediate measures to control it. The best way to prevent and slow down transmission is to be well informed about the COVID-19 virus, the disease it causes, and how it spreads. To protect oneself from this infection, you must thoroughly wash your hands or use an alcohol-based rub frequently and not touch one's face. Always wear a face mask. By taking these strict measures, we can slowly but gradually control the spread of COVID-19.

Coronaviruses are a large family of viruses that commonly cause mild to moderate upper-respiratory tract illnesses like the common cold in humans. Some coronaviruses, such as SARS-CoV, MERS-CoV, and SARS-CoV-2, have evolved to infect humans from animals and can cause more severe respiratory diseases. SARS-CoV-2, the novel coronavirus that emerged in 2019, causes the disease COVID-19 and has spread globally in a pandemic.

Corona Virus Basic Introduction
The document provides information about Coronavirus (COVID-19). It describes how COVID-19 is caused by SARS-CoV-2 virus and spreads mainly through respiratory droplets from infected individuals. Common symptoms include fever, cough and shortness of breath. While most cases are mild, it can progress to pneumonia and multi-organ failure in some cases. The mortality rate is around 2%. Currently there is no vaccine, though some antiviral medications are being tested. Prevention relies on hand washing and hygiene measures.
Coid 19
- Three zoonotic coronaviruses have emerged in the past two decades: SARS-CoV, MERS-CoV, and SARS-CoV-2 (COVID-19). SARS-CoV-2 was first identified in Wuhan, China in December 2019 and has since caused a global pandemic.
- Genetic evidence indicates that bats were likely the original host for all three viruses, which then spread to intermediate hosts like civets, camels, and possibly pangolins before infecting humans.
- While the specific intermediate host of SARS-CoV-2 is still unknown, it is thought to have originated from wildlife sold at a seafood market in Wuhan and then spread via human-to

This document summarizes key information about COVID-19 and compares it to other human coronaviruses like SARS and MERS. It discusses that SARS-CoV-2, the virus that causes COVID-19, is genetically similar to coronaviruses found in bats. While bats may be the reservoir, the intermediate host that transmitted it to humans is unknown. COVID-19 spreads rapidly between humans through respiratory droplets. There are currently no approved vaccines or antiviral treatments, but some drugs are being clinically tested.
Structural Design on Virus and its Diversity
The coronavirus disease 19 COVID 19 is a highly transmittable and pathogenic viral infection caused by severe acute respiratory syndrome coronavirus 2 SARS CoV 2 , which emerged in Wuhan, China and spread around the world. Genomic analysis revealed that SARS CoV 2 is phylogenetically related to severe acute respiratory syndrome like SARS like bat viruses, therefore bats could be the possible primary reservoir. The intermediate source of origin and transfer to humans is not known, however, the rapid human to human transfer has been confirmed widely. In this document we will analyze the structure and diversity of the pathogen and we will also discuss the previous emergence of human coronaviruses like Severe Acute Respiratory Syndrome Coronavirus SARS CoV and Middle East Respiratory Syndrome MERS CoV .

This document discusses COVID-19 and coronaviruses. It defines COVID-19 as a novel coronavirus first identified in Wuhan, China in late 2019. Coronaviruses are a large family of viruses that can cause illnesses ranging from the common cold to more severe diseases like MERS and SARS. The document then provides details on the structure, replication, and transmission of coronaviruses, symptoms of COVID-19, the ongoing global pandemic, and the discovery and identification of SARS-CoV-2 under electron microscopy.
Covid 19 primer
This document discusses COVID-19 and other coronaviruses. It describes coronaviruses as large, positive-sense RNA viruses that infect humans and animals. COVID-19 is caused by SARS-CoV-2, a betacoronavirus related to SARS. It spreads rapidly between humans via respiratory droplets and surfaces. While less deadly than SARS, COVID-19 has a higher transmission rate and has caused a global pandemic. Prevention focuses on social distancing, hand washing, and disinfecting surfaces. Vaccines face challenges due to the virus's ability to mutate.

This document summarizes epidemiological, clinical, and diagnostic findings for common circulating and novel coronaviruses that infect humans, with a focus on infections in children. It discusses four common human coronaviruses (HCoV-229E, HCoV-HKU1, HCoV-NL63, HCoV-OC43) that typically cause mild respiratory illness in children. It also describes two novel coronaviruses, SARS-CoV which emerged in 2002 causing severe acute respiratory syndrome, and MERS-CoV which emerged in 2012 causing Middle East respiratory syndrome, both of which have caused outbreaks with higher mortality rates. The document reviews symptoms, treatments, and prevention strategies for coronavirus infections in children.
Covid19- a brief introduction
This document provides an overview of COVID-19 (coronavirus disease 2019) caused by the SARS-CoV-2 virus. It discusses the virus structure and classification, symptoms of COVID-19 infection, modes of transmission, current lack of vaccines or treatments, and ongoing clinical trials of potential treatments. It also summarizes past coronavirus outbreaks like SARS and MERS, and compares the genetic structure of SARS-CoV-2 to related coronaviruses found in bats and pangolins.
Corona virus current scenario (theoretical outlook)
This document discusses the coronavirus (COVID-19) pandemic. It provides background on coronaviruses, noting they were first identified in 1960 and can cause respiratory illnesses like SARS. The current coronavirus emerged in China in late 2019 and has since spread globally, killing hundreds daily. While studies on animals are limited, research aims to develop treatments like RNA silencing. Prevention efforts are led by CDC and WHO. Coronaviruses can spread through airborne droplets and contact with infected animals or humans. Further research is needed to fully understand transmission and develop effective treatments.
Major Respritory Syndrom and COVID.pptx
The document summarizes key differences between SARS, MERS, and COVID-19. SARS emerged in 2002-2003 with 8,098 cases and 774 deaths. MERS first appeared in 2012 and has caused 2,519 cases and 866 deaths. COVID-19 was identified in late 2019 and has led to over 170 million cases and 3.5 million deaths globally as of mid-2021. The pathogens are coronaviruses and all cause respiratory illness, though COVID-19 has a much lower fatality rate than MERS. No vaccines currently exist for SARS or MERS, while several are available for COVID-19.

DRDO's 2-DG drug for treatment of Covid 19 patients
- 2-Deoxy-D-glucose (2DG) is a glucose analog that was developed as an oral drug for COVID-19 by India's Defense Research and Development Organization (DRDO).
- Clinical trials showed 2DG is effective against COVID-19, reducing recovery time and supplemental oxygen dependence for moderate patients.
- The drug works by inhibiting glycolysis and ATP production within viral cells, blocking synthesis of viral structural components and potentially directly destroying them. No significant side effects were observed during trials.
Deadly Black Fungus In COVID-19 Patients In India
Mucormycosis, also known as black fungus, is a rare but serious fungal infection caused by a group of molds called mucormycetes. It has been occurring in COVID-19 patients in India treated with steroids, which can reduce immunity and increase blood sugar levels. Symptoms vary depending on the infected organ but may include sinus congestion, black lesions, fever and loss of vision. Those at highest risk include diabetics, severely immunocompromised individuals, and those with prolonged hospital stays. The fungus enters through inhalation or skin and spreads rapidly if not treated promptly with antifungal drugs and possibly surgery to remove infected tissue.
