From what I've read/seen it is contagious and considered a communicable disease, did you pick it up from a child who may have it? There are two common types A and B. Type B is spread through the mouth, mucous (runny nose) and fecal matter.
Weak immune systems are not always related to HIV, there are many reasons people have week immune systems, one in particular is defective collagen.


Coxsackie refers to a collection of closely related viruses classified among the enteroviruses, namely those that cause infection after being taken in orally with contaminated food or water and then multiply in the intestines (entero = intestinal). The coxsackie viruses were named after the town Coxsackie, New York. A strain of this virus was discovered there during the investigation of an epidemic that occurred in 1948 alongside a polio epidemic (polio being another enterovirus). The coxsackie viruses are divided into two major subgroups, labeled A and B. There are 23 known coxsackie A viruses that usually cause only enteric diseases, and 6 known coxsackie B viruses, which are the ones of greatest concern because of their ability to cause serious diseases beyond the intestinal tract. Coxsackie B3 has been found to be one of the main causes of certain debilitating or life-threatening diseases, such as viral myocarditis.

-- In adults, viral myocarditis and dilated cardiomyopathy can occur if the virus infects the heart muscle. Coxsackie B viruses are estimated to be responsible for at least 50% of the cases of infection-caused heart diseases. For reasons yet unknown, the cardiac disease caused by this virus mainly occurs in middle-aged men, with onset occurring, on average, around age 42. The cardiac disease becomes apparent about two weeks after exposure to the virus.
