Viruses are tricky. They can be communicable. The symptoms present themselves as the body fights the virus. You can boost your immune system by taking echinacea (you, 300 mg 3 times daily), goldenseal, and Vitamin C (500 mg 1-2 times daily).

Thanks leewhiz, today it's my youngest son's turn again in three weeks, I just brought him to the hospital. The doctor advise to have his blood test in case it persist for 4 days. Thanks for your advise I'll check on the Vit C but may I know what are the rest of them are they Vitamins too sorry I never heard of the names I am not from the States.
