Abstract:

In December 2019, a new coronavirus species from the market for seafood in China's city of Wuhan soon became a pandemic and became a common problem for all countries. Coronavirus-2 is a single-chain, positive polarity, covered, ribonucleic acid virus. COVID-19 is targeted by the respiratory system and is transmitted from humans to humans through drops. The survival of the virus on unlife surfaces also makes it possible to infect through contact. The symptoms of the disease include fever, breathing difficulty, coughing. Although the majority of cases have mild symptoms, there are also severe clinical conditions such as pneumonia, acute respiratory failure syndrome, multiple organ insufficiency and death. Use of mask, social distance and handwashing plays a key role in preventing the COVID-19 epidemic. There is still a lot to be learned about this newly recognised infection. Keywords: Coronavirus, COVID-19, pandemic, epidemiology. In December 2019, a novel coronavirus originating from a seafood market in Wuhan, China became a pandemic in a short time and a common problem for all countries. Severe Acute Respiratory Syndrome Coronavirus 2 is a single-chain, positive polarity, and enveloped ribonucleic acid virus. COVID-19 targets the respiratory system and human-human transmission occurs by inhalation of respiratory droplets. The virus's survival on inanimate surfaces also makes it possible to be transmitted by contact. Symptoms of the disease include fever, shortness of breath, and cough. Although mild symptoms are present in the majority of the cases, there are also severe clinical conditions such as pneumonia, acute respiratory distress syndrome, multiple organ failure, and death. Mask use, social distancing, and hand-washing play a key role in preventing the spread of COVID-19. Much still needs to be learned about this newly recognized infection.
