Answer 1

9) Fatality rate of Covid 19 is different across different age group. It is more in older age i.e age > 60, as this people have comorbitidies like diabetes , cancer, hypertension, etc which compromise their immune system, also with increase in age their immune system also decreases that's why death rate in this age group is alone 21%, highest among all age group. Also this virus will not affect much the younger population unless untill they are not immunocompromised like having diabetes , any respiratory disorders, cardiovascular disorders. Pre existing illness put the patient in higher risk.

11) symptom in mild cases are cough, headache, col, bodyache.

12) severe case will have high fever over 100.4F, shortness of breath and dry cough.

13)A.R.D.S stands for Acute respiratory distress syndrome.

14) Normally in healthy people, lungs have alveoli as it's functional unit, it has very very thin wall so that oxygen can easily goes to blood vessels from the alveoli sac. Virus damage both the wall and lining of alveoli as well as capillary vessel, the debris will line the wall, also damage to capillary will cause plasma exudation, resulting in making wall thick. Oxygen now not able to easily pass to blood vessels resulting in respiratory distress and. The patient will develop shortness of breath .

15) R naught is the expected number of secondary case that produce by a single infection or primary case. It tells about how contagious the infection disease is.
