SARS-CoV-2 (COVID-19)
SARS-CoV-2 is a virus that causes COVID-19, a disease first identified in late 2019. It primarily spreads through respiratory droplets from coughs, sneezes, or talking. Infection can lead to symptoms ranging from mild (cough, fever) to severe (difficulty breathing, pneumonia), and can be particularly dangerous for older adults and those with underlying health conditions. Preventive measures include vaccination, wearing masks, and practicing good hygiene. The pandemic has had significant impacts on health, economies, and daily life worldwide, prompting ongoing research to understand the virus and manage its spread.
