Regional Variation in Travel-related Illness Acquired in Africa, March 1997--May 2011, M. Mendelson et al.
Africa’s diverse geography, ecosystems, and climate make that continent a
popular tourist destination, yet we do not clearly understand how that
diversity affects travellers’ risks for exposure to various illnesses. A large
collaborative effort using a database of travelers found that the highest risk
for gastrointestinal illnesses and dog bites was in northern Africa; the
greatest risk for illnesses with fever in sub-Saharan Africa; the highest risk
for malaria in central and western Africa; the highest risk for
schistosomiasis, strongyloidiasis, and dengue in eastern and western Africa;
and the highest risk for eye worm infection in central Africa. Understanding
what the greatest health risks are in different parts of Africa can help with
dispensing travel advice, diagnosing illness in returned travelers, and
deciding where in Africa to visit.
