In the past, children's vaccination rates have been low – as of 2012, 60% of the children in Haiti under the age of 10 were vaccinated,[308][309] compared to rates of childhood vaccination in other countries in the 93–95% range.[310] Recently there have been mass vaccination campaigns claiming to vaccinate as many as 91% of a target population against specific diseases (measles and rubella in this case).[311] Most people have no transportation or access to Haitian hospitals.[312]
The World Health Organization cites diarrheal diseases, HIV/AIDS, meningitis, and respiratory infections as common causes of death in Haiti.[313] Ninety percent of Haiti's children suffer from waterborne diseases and intestinal parasites.[314] HIV infection is found in 1.71% of Haiti's population (est. 2015).[315] The incidence of tuberculosis (TB) in Haiti is more than ten times as high as in the rest of Latin America.[316] Approximately 30,000 Haitians fall ill with malaria each year.[317]
Most people living in Haiti are at high risk for major infectious diseases. Food or water-borne diseases include bacterial and protozoal diarrhea, typhoid fever and hepatitis A and E; common vector-borne diseases are dengue fever and malaria; water-contact diseases include leptospirosis. Roughly 75% of Haitian households lack running water. Unsafe water, along with inadequate housing and unsanitary living conditions, contributes to the high incidence of infectious diseases. There is a chronic shortage of health care personnel and hospitals lack resources, a situation that became readily apparent after the January 2010 earthquake.[318] The infant mortality rate in Haiti in 2013 was 55 deaths per 1,000 live births, compared to a rate of 6 per 1,000 in other countries.[319]
