CORONA

CORONA typically refers to the coronavirus family, a group of viruses that can cause illnesses ranging from the common cold to more severe diseases. The most well-known recent example is SARS-CoV-2, which causes COVID-19. These viruses are named for the crown-like spikes on their surface. They spread mainly through respiratory droplets when an infected person coughs, sneezes, or talks. Symptoms can include fever, cough, and fatigue, with severe cases leading to pneumonia or organ failure. Preventive measures include good hygiene, masks, and vaccination. Understanding the virus helps in controlling its spread and protecting public health.
