They report that the mortality rate from the common infectious diseases, already by far the biggest killer in developing nations, may be driven in part by pesticide exposure. Existing studies makes this highly plausible but are insufficient for definitive proof. What is clear is that pesticides do impair immune system function in specific cases, sometimes severely, and that the impact of this additional immunosuppression may be the final straw for people already vulnerable to infectious diseases.
Children are particularly susceptible to the effects of pesticides on their immune systems.
Children from these areas were three times more likely to have infectious diseases of the digestive tract, and two to five times more likely to have infectious diseases of the respiratory tract. Workers in pesticide factories and on farms in the area exhibited elevated rates of infectious diseases of the digestive, urinary, respiratory, and female genital tracts. We are calling on the World Health Organization to spearhead a large-scale research program into links between pesticides and damage to the immune system, and on major pesticide companies, multilateral banks, and the W.H.O.'s member governments to finance this important public health campaign.
