When viral particles of a certain virus enter the yound child body, they replicate rapidly. In about how many hours do the number of viral particles has doubled? How many viral particles reach to appointed amount the immune system will response in the yound child body? The first response of the immune system is fever. The rise in temperature lowers the rate at which the viral paricles replicate to how many percentages every four hours, but the immune system can only eliminate these particular viral particles at the rate of about how many viral particles per hour. Often the yound child do not seek medical attention immediately as they think they have a common cold. If the number of viral particles, however, reaches how many viral particles? The young child wil die.
Give me some evident sources..thanks
