What if you were exposed to just a tiny bit of COVID19 in a controlled manner and under close watch? Would that make your chances of having a mild case and surviving it much higher? If so, could you become plasma donor for your family members who are more vulnerable?
"Are some people more at risk than others?
Yes – health workers who have to get close to patients are at particularly high risk and this is why doctors and nurses have been getting so angry about shortages of personal protective equipment such as gloves, visors and masks."
"Such shortages are a problem around the world – and in France doctors are suing the government for failing to stockpile protective equipment. "

When viruses invade our cells, they hack the machinery of the cells to copy and multiply themselves. Thus their numbers grow exponentially in our bodies; the same way that the growth of the infection among people is exponential...
If a single virus enters your body and in each unit of time generates N new viruses, then after M units of time, you'd have N^M copies. But if the initial dose is K viruses, then after M units of time you'd have K x N^M copies in the body, which is a K times bigger viral load.
