COVID-19

COVID-19 is a disease caused by the novel coronavirus SARS-CoV-2, which emerged in late 2019. The term COVID-19 stands for “Coronavirus Disease 2019.” It primarily spreads through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. Common symptoms of COVID-19 include fever, cough, fatigue, shortness of breath, loss of taste or smell, and muscle aches. While many people experience mild to moderate symptoms, the disease can lead to severe respiratory illness and complications, particularly in older adults and those with underlying health conditions.

COVID-19 led to a global pandemic, prompting widespread public health measures, including social distancing, mask mandates, travel restrictions, and the development of vaccines. Vaccination efforts have been critical in controlling the spread of the virus and reducing the severity of the disease. Variants of the virus have emerged, leading to ongoing monitoring and adaptations in public health responses. The impact of COVID-19 has been profound, affecting healthcare systems, economies, and daily life worldwide.
