THAILAND — All the boys and their coach have been rescued from the cave in Thailand, but they may have to face another challenge: cave disease.<br /><br />Cave disease, also called histoplasmosis, is a fungus infection that is "aided by nutrients it gets from bat and bird droppings," reports ABC News.<br /><br />The disease is reportedly transmitted via air, with the fungus becoming airborne through its spores that are so tiny they are "undetectable to the human eye."<br /><br />However, the disease itself is not contagious from person to person.<br /><br />According to the CDC, any movement that disturbs the ground like digging or even walking can spread the disease.<br /><br />Histoplasmosis may affect those with a weaker immune system, causing the disease to "spread from the lungs to … the brain."<br /><br />Those who don't get sick may appear to have a flu, or have body aches and chest pain.<br /><br />One way to prevent "cave disease" is to avoid walking into any caves where bird and bat droppings are suspected to be there.
