The main issue of COVID-19 is that it is a highly contagious respiratory illness caused by the novel coronavirus SARS-CoV-2. It has led to a global pandemic, resulting in widespread illness, death, economic disruptions, and social restrictions. The virus spreads easily from person to person through respiratory droplets, making it difficult to contain and control. Additionally, the severity of symptoms can vary widely, from mild flu-like symptoms to severe respiratory failure and death, making it a challenging and unpredictable disease to manage.
