Vector alert: Anopheles stephensi invasion and spread - Horn of Africa, the Republic of the Sudan and surrounding geographical areas, and Sri Lanka (Information Note)
Anopheles stephensi, a highly competent vector of Plasmodium falciparum and P. vivax, is considered an efficient vector of urban malaria. The World Health Organization (WHO) considers the spread of An. stephensi to be a major potential threat to malaria control and elimination in Africa and southern Asia. This vector alert has been developed to urge WHO Member States and their implementing partners – especially those in and around the Horn of Africa, the Republic of the Sudan and surrounding geographical areas, and in Sri Lanka – to take immediate action.
