World Health Officials Describe Progress Against Tetanus, H.I.V. and Malaria
Infant and maternal tetanus was officially eliminated from the Americas this year, the Pan American Health Organization
announced on Thursday. At one time, the infection killed about 10,000 newborns annually in the Western Hemisphere; tetanus
still kills about 35,000 infants around the world. It was one of several significant global health advances, including new programs
against malaria and H.I.V., announced last week in conjunction with the meeting of the United Nations General Assembly in
New York.
Haiti was the last country in the Americas to eliminate neonatal tetanus. That does not mean complete eradication,
because the bacteria that cause tetanus exist everywhere in soil and animal droppings. Rather, elimination means that
thanks to vaccination of mothers and clean birth procedures — less than one case occurs per 1,000 live births.
The Americas have generally led the world in eliminating diseases for which vaccines exist. In this hemisphere, smallpox
was eliminated in 1971, polio in 1994, rubella in 2015 and measles in 2016 (the diseases are sometimes reintroduced, as
measles was at Disneyland in 2014, but outbreaks are usually brought quickly under control).
Also this week, the President’s Malaria Initiative said it would expand its work to new countries in West and Central
Africa, protecting 90 million more people. The initiative, founded in 2005 as part of the United States Agency for International
Development, has been a major force in driving down worldwide malaria deaths by about 40 percent in the past decade. The
disease most often kills young children and pregnant women. The expansion in Cameroon, Ivory Coast, Niger, Sierra Leone
and Burkina Faso was made possible because Congress increased funding for the initiative in fiscal year 2017, a representativ
said
In his speech to the United Nations on Tuesday, President Trump praised the malaria initiative and the President’s
Emergency Plan for AIDS Relief as examples of leadership in humanitarian assistance by the United States.
A combination of aid agencies, drug companies and g
cocktail to treat H.I.V. would soon be available to 92 countries, including virtually all of Africa, for about $75 a year. The new AIDS cocktail is the first available in poor countries to contain dolutegravir, which is widely used in wealthy countries because it is highly effective and has few side effects. The pill also contains lamivudine, an older but still effective drug, and tenof
disoproxil fumarate, another modern drug whose inclus
effects and resistance.
Almost 37 million people in the world have H.I.V., according to Unaids, the U.N.’s AIDS-fighting agency, but fewer than 20 million are now on antiretroviral medicine, which not only saves their lives but prevents them from passing on the disease.
