Coronavirus disease (COVID-19)
Coronavirus disease (COVID-19) is an infectious illness caused by the SARS-CoV-2 virus. It primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks. COVID-19 emerged in late 2019 and quickly became a global pandemic, affecting millions of people worldwide.
Common symptoms include fever, cough, and difficulty breathing, but they can range from mild to severe. Some people may experience fatigue, loss of taste or smell, sore throat, or headaches. While most individuals recover without needing special treatment, severe cases can lead to complications like pneumonia or organ failure.
Prevention is key to controlling the spread of the virus. Measures such as wearing masks, practicing physical distancing, and maintaining good hand hygiene are essential. Vaccines have been developed and are crucial in reducing the severity and spread of COVID-19.
Staying informed about COVID-19 and following guidance from health authorities helps protect yourself and others.
