Colds

FALLACY: Rainy and cold weather cause colds.

FACT: The cold is the most common human ailment and children ages on to five are most susceptible. Colds are spread by respiratory droplets or by contaminated hands or objects. Although the incidence of colds is higher during the rainy or cold season, exposure to chilling or dampness is considered to be of little significance. Any one of up 200 viruses( such as the rhinoviruses, coronaviruses, or respiratory syncytial virus) can cause colds, to which it seems no one is immune. Infection with a viral strain confers only temporary immunity to that strain.
