Corona virus disease 2019 (English: coronavirus disease 2019, abbreviated as Covid-19) is an infectious disease caused by SARS-CoV-2, a type of coronavirus. This disease causes a pandemic. People with COVID-19 may experience fever, dry cough, and difficulty breathing. Sore throat, runny nose, or sneezing are less common. In the most susceptible sufferers, the disease can lead to pneumonia and multiorgan failure. The infection is spread from one person to another through droplets from the respiratory tract that are often produced when coughing or sneezing. The time from exposure to the virus to the onset of clinical symptoms ranged from 1–14 days with an average of 5 days. The standard method of diagnosis is the reverse-transcription polymerase chain reaction (rRT-PCR) assay of a nasopharyngeal swab or sputum sample with results within a few hours to 2 days. Antibody tests from blood serum samples can also be used with results within a few days. Infection can also be diagnosed from a combination of symptoms, risk factors, and a computed tomography scan of the chest showing symptoms of pneumonia. Washing hands with soap, keeping a distance from people who are coughing, and not touching the face with unclean hands are recommended steps to prevent disease. this. It is recommended to cover the nose and mouth with a tissue or bent elbow when coughing. The World Health Organization (WHO) and the US Centers for Disease Control and Prevention (CDC) recommend that people who suspect they have been infected wear a surgical mask and seek medical advice by calling a doctor instead of visiting a clinic right away. Masks are also recommended for those caring for someone suspected of being infected but are not for use by the general public. Several countries have succeeded in making a Covid-19 vaccine. However, it is still being researched and developed further. Management provided includes treatment of symptoms, supportive care, and experimental measures. The case fatality rate is estimated to be between 1–3%.
