Corona virus epidemiology: a review article

Kamlesh Sharma, Ram Lal Sharma, Vanita Sharma


Corona virus disease-2019 is an infectious disease caused by SARS-Co-2. The disease started in December 2019 in Wuhan, China resulting in pandemic. Common symptoms are fever, cough and shortness of breath. Loss of apetite, anosmia, conjunctivitis and diarrhoea are fewer common symptoms. The disease is mild in most people but may progress to pneumonia, acute respiratory distress syndrome in elderly patients and those with co-morbidities. The infection is spread from one person to another via respiratory droplets or contact with infected droplets. Preventive measures include frequent and thorough hand washing, maintaining distance from potential transmitter and not touching one’s face. Mask is recommended to suspects and to their caregivers. Presently there is no vaccine or specific treatment for COVID-19. Management involves treatment of symptoms, supportive care. World health organisation declared the 2019-2020 CoV outbreak a pandemic and a Public Health Emergency of International concern with death rate of 3.4%.
