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).
Rated 5 out of 5 by Sheila102005 from I took my daughter, grandson's fiancÃ©, their 2 children one is 15 the other 9, a good friends son who is 10 and myself to see Cirque. I didn't hear any one say any thing after the show started. My great granddaughter she is 9, has not stopped talking about the program.
