COVID 19 is a surprise that no one saw coming. When the variant infected everyone else and caused a worldwide uproar, the entire world was in shock. COVID, also known as SARS-CoV-2 coronavirus, is an infectious disease that may be caused by contamination because the exact cause is unknown. Some people experience mild symptoms, while others experience severe symptoms that require hospitalisation.
The most well-known fact about the COVID virus is that as it spreads, it changes, mutates, and creates variants, each of which is stronger than the previous one. Here are some of the fundamental facts about COVID 19 based on its symptoms and mode of transmission.
Variants can last longer
Because variants remain on the surface for a longer period of time, it is recommended to sanitise before and after going out and returning home. When a person sneezes or coughs, he or she has respiratory droplets in their hands that can spread to anything they touch. The virus has been reported to last up to 2 to 3 days on plastics and up to 24 hours on cardboard sheets. In crowded places with poor ventilation, the virus can also spread through the air.
Babies are more infected
Because of their weakened immune systems, babies are more susceptible to COVID virus infection than adults. At the start of the pandemic, children under the age of one year and seniors aged 50-60 were more affected than people of other ages. Some children with current or recent SARS-CoV-2 infection develop a multisystem inflammatory syndrome (MIS).
COVID 19 can be asymptomatic as well. This means that people infected with the virus never get a cold, sneeze, cough, or other symptoms. This may be fortunate for infected people, but it can be dangerous for others because asymptomatic people may never know if they are infected and can unknowingly spread the virus to others. Over 40% of those infected have no symptoms.
Type A blood
People with blood group A are more susceptible to the virus than people with other blood groups. Infection may also cause respiratory failure in type A patients. People with type O blood have the lowest chance of getting infected.
Binds the humans cells
A severe acute respiratory syndrome spread throughout Asia, infecting approximately 8000 people. This syndrome was caused by a virus similar to the one that caused COVID (SARS-CoV-2). But there’s a problem. Why is COVID 19 more deadly than severe acute respiratory syndrome? According to researchers, the new coronavirus (SARS-CoV-2) binds to human cells 10-20 times more than SARS-CoV.
Of course, the virus can infect you again. COVID has several variants, and you can become infected with any of them. Immunity and protection can last up to 6-12 months, but the virus can still infect you.
These are some of the well known facts about COVID and its virus. You can learn about tips and tricks to prepare when the pandemic hits again.
