Coronaviruses are large group of viruses that cause illness in humans and animals.Rarely, animal coronaviruses can evolve and infect people and then spread between people such as has been seen with and SARS outbreak in 2003 which started from China.The outbreak of Novel coronavirus disease (COVID-19) was initially noticed in a seafood market in Wuhan city in Hubei Province of China in mid-December, 2019, has now spread to 215 countries worldwide WHO declared COVID-19 a pandemic on 11th March, 2020. ACE-2 receptor has been identified as a functional receptor for SARS-CoV and is highly expressed on the pulmonary epithelial cells. Ranges from 1 to 14 days. Median incubation period around 5 days. Period of infectivity: from 2 days before symptom onset to around 7 to 10 days after Symptom onset. Autopsy findings have revealed that endothelial damage of pulmonary vasculature & micro vascular thrombosis and extensive alveolar and interstitial inflammation (known as diffuse alveolar damage) DAD. Macro vascular Thrombosis in Pulmonary and other Large and Medium sized Vessels cause large areas of Consolidation in the Lungs. One study found that 66 out of 70 people who had COVID-19 pneumonia still had lung lesions visible by CT scan when they left the hospital. A recent study Trusted Source followed up on 71 individuals 15 years after they had SARS, which develops from a related coronavirus. The researchers found that lung lesions decreased significantly in the year after recovery. However, after this recovery period, the lesions plateaued. Most people who get COVID-19 have mild or moderate symptoms like coughing, a fever, and shortness of breath. But some who catch the new coronavirus get severe pneumonia in both lungs. COVID-19 pneumonia is a serious illness that can be deadly.
