No chlorination of water supplies is suspected
Mérida, Yucatán -
Diagnosed cases of Hepatitis A, an infectious disease of the liver which typically results from poor sanitation and feces-contaminated food and water, rose sharply in the state through Sept. 1 according to the capital city's main daily, Diario de Yucatán.
The failure by state municipios, or counties, to adequately chlorinate reservoirs in local water districts may be the reason, the paper reported in its morning edition today. Yucatán has 106 municipios, each with an administrative center (county seat) and commonly other towns as well.
As the state health department chart below illustrates, Yucatán easily leads Mexico's 32 entities in HEP A statistics, with 1,015 cases to date in 2014, or roughly 45 per 100,000 residents. The national average is 8.2.
Hepatitis A can easily be transmitted by contact with an infected person, even by one who presents without symptoms.
