YELLOW FEVER in Argentina, Brazil, Congo, Republic of the, Nigeria, Peru, Suriname, Uganda
June '19 - Case numbers for yellow fever are thought to be greatly under-reported; the World Health Organization (WHO) estimates that there are approximately 200,000 cases of yellow fever worldwide per year, with 30,000 deaths; 90% of these cases occur in Africa. According to WHO, yellow fever is endemic in tropical areas of Africa and Latin America. WHO also notes, the number of yellow fever cases has increased over the past two decades due to declining population immunity to infection, deforestation, urbanization, population movements and climate change.
In early 2017, the Brazilian Ministry of Health reported outbreaks of yellow fever in several eastern states, including areas where yellow fever was not traditionally considered to be a risk. Although virus spread decreased by mid-2017, yellow fever cases have reappeared in several states since the end of 2017, especially in São Paulo State, including areas close to the city of São Paulo. In early 2018, the GeoSentinel Surveillance System reported a case of yellow fever in an unvaccinated Dutch traveler who had stayed near the São Paulo metropolitan region.
In Nigeria, the local Centre for Disease Control has reported an ongoing outbreak of yellow fever that began in September 2017. Laboratory-confirmed yellow fever cases have been reported in at least seven states, and a number of people have died.

MALARIA in Brazil, Cape Verde, South Africa
June '19 - Malaria is a potentially deadly mosquito-borne disease found in many countries throughout the the world.
Cases of malaria have been reported in parts of South Africa, Costa Rica and Brazil.
Public health officials in Brazil have reported an outbreak of locally transmitted malaria in the town of Wenceslau Guimarães in Bahia State. Local transmission means that mosquitoes in the area may be infected with malaria and spreading it to people. Although mosquitoes that spread malaria are present in Bahia State, malaria is not usually found there; this outbreak is believed to have started with an infected person who traveled from Pará State, where malaria is known to spread.
In South Africa, as of March 2018, multiple cases have been reported in travelers to Limpopo Province.
CDC now recommends that travelers to the western Waterberg district of Limpopo Province take prescription medicine to help prevent malaria. CDC previously recommended these medicines only for people traveling to Vembe or Mopane cities in Limpopo province.
A malaria epidemic has been declared by the Burundi Ministry of Health. All of the country’s 18 provinces are reporting higher numbers of malaria cases than expected and nine provinces—Gitega, Kirundo, Muyinga, Karusi, Kayanza, Ngosi, Ruyigi, Cankuzo and Cibitoko—have been especially hard-hit.
CDC continues to recommend that travelers to Burundi take prescription medicine to prevent malaria.
