<span>I imagine the intended correct answer here is B. Chromosomal disease. However, it is worth mentioning that the correct term to use here would be chromosomal disorder. Chromosomal disorders are usually due to either the addition or subtraction of one chromosome.</span>
Measles<span> virus infection is presumed to be sustained through an unbroken chain of</span>human-to-human transmission. So the term I would use is Human Reservoirs because m<span>any common infectious diseases have human reservoirs. Diseases that are transmitted from person to person without intermediaries . And measles is an example of Human reservoirs. </span>

Plus when you take punches that can fatigue you.”
