Dr. Dave On Call

In Episode 1, we discuss the origins of COVID-19, how COVID-19 makes us sick and the symptoms of COVID-19 that should concern us.

What does COVID-19 actually mean? CO=Coronavirus VI=Virus D=Disease 19=2019 (year discovered)

The origins of COVID-19: No a person did NOT eat bat soup. However, bats were likely the hosts of COVID-19 and a pangolin (miniature anteater) became the reservoir. When sold at an animal/wet market in Wuhan, China, the pangolin likely transmitted COVID-19 to the animal handler who was Patient 0. This individual spread it to a number of individuals and because of the long incubation period it became a pandemic rather quickly

How does COVID-19 make us sick? It needs to enter our healthy cells to replicate, make more COVID-19 and spread to other healthy cells. In a cascade of events, COVID-19 hijacks our own cellular machinery in order to make more COVID-19. In a matter of days, COVID-19 has infected billions of our cells and we become ill.

What are the warning symptoms of COVID-19? There are a number signs and symptoms we need to look out for, however, FEVER, SHORTNESS OF BREATH and DRY COUGH are the big three. Sure, odd symptoms like loss of smell and taste have been reported, as well as mild symptoms too. Itchy/watery eyes and sneezing are likely seasonal allergies.
