Fever can support the immune system's attempt to gain advantage over infectious agents, such as viruses and bacteria, and it makes the body less favorable as a host for replicating viruses and bacteria, which are temperature sensitive. Infectious agents are not the only causes of fever, however.
Your sister's grandson is your great nephew. You are his great aunt (if you are a woman) or his great uncle (if you are a man).
The child your uncle has with someone to whom youâre not related is, therefore, 12.5 percent related to you. But in the case of double cousins, where both parents are siblings of your parents, the relationship is obviously doubled to 25 percentâthe same degree as with a half-sibling.
