In December 2019, Chinese authorities reported a virus infecting citizens, known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing COVID-19. The virus spreads primarily through droplets from coughing or touching surfaces. It infiltrates human cells, multiplies, and triggers the immune system, potentially leading to severe lung damage. The pandemic's outcome depends on a slow or fast start, with slow responses being crucial for minimizing its impact. Public measures like handwashing, social distancing, and quarantines play a vital role in controlling the virus. Researchers work on medicines and vaccines to combat the pandemic.
