COVID-19

COVID-19 is a contagious disease caused by the novel coronavirus SARS-CoV-2. First identified in December 2019 in Wuhan, China, it quickly spread globally, leading to widespread health, social, and economic impacts. The disease primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks, but can also be transmitted via surfaces and close contact with infected individuals. Symptoms of COVID-19 can vary widely, ranging from mild respiratory issues to severe pneumonia, and can include fever, cough, fatigue, loss of taste or smell, and difficulty breathing. Some individuals may be asymptomatic yet still carry and transmit the virus. In response to the pandemic, public health measures such as social distancing, mask-wearing, and vaccination initiatives have been implemented worldwide. Vaccines have been developed and distributed to reduce transmission and severity of the disease, and various variants of the virus have emerged, continuing to influence public health strategies.
