Coronavirus Outbreak

 

 

 

Structure/Function

The virus that is widely known as, novel coronavirus SARS CoV-2 was described as pandemic. The virus is origin comes from betacoronavirus genus which has been seen in bats. The betacoronavirus causes extreme damage to the respiratory in humans. Its structure consists of outer proteins that cover the spore, hemagglutinin eterease dimer present in betacoronaviruses, membrane glycoprotein, an envelope protein, a nucleoclapid protein, and RNA. The virus infects the respiratory system when different sizes of droplets are transmitted between people. As of right now there is no evidence of the coronavirus being airborne.

 

Spread

If someone is sneezing or coughing the people nearby have a higher chance of becoming infected by possible infectious droplets. It can be transmitted through direct contact or by touching surfaces that have the infectious droplets from the coronavirus. Being within 3 to 6 feet of someone who is infected with coronavirus increase the chance of spreading. Being coughed on or by your face can cause a human to become infected. If someone is sick it has been advised to sneeze into our elbows or tissue then discard it and immediately wash our hands. Wearing a mask if your sick is another method to stop the spread.

 

Human Health

Coronavirus is able to infect cells with the molecular key attached to the virus. The molecular key is scientifically is as the a spike protein (S-protein). The surface of respiratory cells - ACE2 is grabbed by the S-protein and the virus is allowed to enter. Also, the stickiness of the virus is considered to be the reason the coronavirus has been able to transmit so easily between humans. Essentially, the coronavirus has the key and our respiratory cells have the lock. The virus is known to affect the health of people with preexisting illnesses more so than people that don't have them. People who at a higher risk are those that are suffering from high blood pressure, heart disease, diabetes, renal failure, liver disease, cancer patients, people with a body mass index over 40, and those with asthma. It has been said that people with asthma need to be more cautious with going throughout their community. 

 

Prevention

Once again it can be prevented by washing your hands with warm water for 20 to 30 seconds once you have coughed or sneezed or hand sanitizer with 60% of alcohol content. Avoid touching your eyes, nose or mouth and don't share makeup, food, or eat off of someone else's dishes. If you have asthma take your prescribed medication to prevent an asthma flare up.
