The World Health Organization (WHO) declared Egypt "malaria-free" on Sunday, stating that the achievement marks the end of a "nearly 100-year effort by the Egyptian government and people."
To be considered malaria-free, a country must report no local transmission of the disease for three years. After dealing with malaria since 4,000 B.C., Egypt began its path to eradication in the 1920s by limiting mosquito-attracting agriculture, such as rice.
