Question

2.) Discuss in detail why masks are relatively ineffective as a means of preventing infection by coronavirus, especially in regards to cloth masks; also discuss when, where and who masks appropriate and recommended for.

3.) What Percentage of alcohol, bleach, and Hydrogen peroxide are effective at eliminating Coronavirus 19.

4.) Despite having a similar profile to SARS, Covid-19 is already more widespread with much larger morbidity and mortality totals. What factors do you think accounted for the disparity of these 2 outbreaks

5.) MERS is also a coronavirus; however, it is classified as an endemic (localized) illness and has never caused an outbreak. Why is this?

Answer 1

2. The first thing we need to understand that could 19 is not an airborne disease. The transmission of this disease is through droplets. So droplets can't stay for a longer time in the air. So using a mask is ineffective if we want to protect ourselves from the disease.

But on the other hand, if we want not to spread the disease if we already have, we can use a mask. Because these viruses can survive on different surfaces for many days. So if we sneeze or cough, droplets will fall on many surfaces like door handles, atm, etc. And if the same is used by others they will get this virus. So if we used a mask, the spilling of droplets to the surface could have avoided!

3.alchohol more than 60% and bleach more than 0.1% and hydrogen peroxide more than 0.5% can work well against covid 19.

5. The infectivity of covid is very very higher than that of MERS. MERS thought to have a very low transmission. MERS is only infected among very closely mingled persons. But the story is different for covid 19. On average, one infected person infected 3 others! The infectivity of covid is a dangerous thing than any other. So that is why covid 19 is widespread and a pandemic.
