Covid 19
The coronavirus, specifically SARS-CoV-2, is the virus that causes COVID-19. It emerged in late 2019 and led to a global pandemic. Coronaviruses are a large family of viruses that can cause illnesses ranging from the common cold to more severe diseases.
Key points about the coronavirus and COVID-19:
Transmission: The virus spreads primarily through respiratory droplets when an infected person coughs, sneezes, or talks. It can also spread by touching surfaces contaminated with the virus and then touching the face.
Symptoms: Common symptoms include fever, cough, fatigue, and loss of taste or smell. Severe cases can lead to pneumonia, acute respiratory distress syndrome (ARDS), and death.
Prevention: Preventative measures include wearing masks, practicing physical distancing, frequent handwashing, and vaccination.
Vaccination: Vaccines have been developed and distributed globally to help prevent severe illness and death from COVID-19. Various vaccines, such as those developed by Pfizer-BioNTech, Moderna, and Johnson & Johnson, have received emergency use authorization.
Variants: The virus has mutated over time, leading to the emergence of new variants. Some variants may spread more easily or evade immunity from previous infection or vaccination to some extent.
