Q1/Write about the genetic and immunlogiclal factors contributing to severe covid-19 ?
-Genetic factors, age, comorbidities, hyperactive immune response, vitamin D deficiency, and prior exposure to related coronaviruses are all potential contributors to the severity of COVID-19 infections. However, not all individuals with these risk factors will develop severe disease, and other factors may also play a role.
Q2/How does COVID- 19 affect smell loss (anosmia)? And have symptoms of smell distribution changes as the virus evolved?
-COVID-19 can cause a loss of smell or changes in the sense of smell, and it is thought to be related to the virus's ability to infect cells in the nasal cavity. There is some evidence to suggest that the severity of anosmia may be a predictor of the severity of COVID-19, but it is unclear whether the symptoms of smell loss have changed as the virus has evolved.

A patient presents to his family physician after 6 weeks of his travel to a tropical region. The patient has nonhealing and a punched-out ulceration with a pseudomembrane on his hand. The Gram stain smear prepared from a swab which has been taken beneath an adherent membrane revealed gram positive club-shaped bacilli.
