SARS-CoV-2, commonly known as the novel coronavirus, is a highly infectious virus that causes the respiratory illness COVID-19. It was first identified in Wuhan, China in December 2019 and has since spread globally, causing a pandemic that has disrupted the lives of millions of people.

The virus is transmitted through respiratory droplets when an infected person coughs, sneezes, or talks. It can also be spread by touching surfaces contaminated with the virus and then touching one’s face.

Symptoms of COVID-19 include fever, cough, shortness of breath, and fatigue. Some people may also experience muscle aches, loss of taste or smell, and gastrointestinal symptoms.

To prevent the spread of SARS-CoV-2, it is important to practice good hand hygiene, wear a mask, and practice physical distancing. Vaccines are also available to protect against the virus.

Although the pandemic has been a challenging time for many, it has also brought about advancements in science and medicine. Researchers and healthcare professionals are working tirelessly to develop new treatments and vaccines to combat the virus and help bring an end to the pandemic.
