Malaria, a disease that afflicts hundreds of millions of people and causes more than a million deaths per year, can be prevented. The simplest way is to avoid the bite of a parasite-bearing mosquito, but this strategy is generally impossible in endemic countries where mosquito assaults are fierce. Spraying insecticides and treating bed nets can go far in controlling the mosquito vectors and reducing disease transmission, but vaccines are considered by many to be a long-term solution to prevent infection and disease.
