Susceptibility/Predisposition to Infectious Disease

For this Week’s Discussion Board, you are asked to research factors that impact our immune system and affect our susceptibility to infectious diseases. Go to PubMed and find at least one peer-reviewed article to summarize and discuss. For example, you may choose to look at 1) links between human genetic variation and susceptibility to a specific infectious disease (e.g., Neanderthal DNA and Covid), 2) link between aging and a specific infectious disease, or 3) links between stress, nutrition, or exercise and a specific infectious disease. Other topics are welcomed.

Please be sure to mention:

The factor you explored
The disease(s) implicated
How the factor affects susceptibility to disease (i.e., mechanism)
Something that you found interesting in your research.

At least 3 referencawzes with one from a scholarly article.
