MORBIDITY PATTERNS


Although infectious diarrhea and severe respiratory infections have declined significantly as causes of mortality, they remain major illnesses in the early 1990s. Reported cases of infectious diarrhea escalated dramatically from 1,661 per 100,000 residents in 1980 to 2,906 in 1990, and to 4,685 in 1991. During the same period, severe respiratory infections climbed from 3,334 cases per 100,000 residents in 1980 to 10,800 in 1990, and to 13,732 in 1991.

Mexican health officials reported substantial progress in relation to several illnesses controllable by vaccination. Pertussis declined from 122.6 cases per 100,000 residents in 1930 to 4.4 cases in 1980, to 1.3 cases in 1990, and to only 0.2 cases in 1991. Chiapas's rate in 1991 stood at ten times the national average, however. The total number of cases of poliomyelitis declined from 682 in 1980 to seven in 1990 and to zero in 1991. The government recorded only a single case of diphtheria in 1991. Measles epidemics continued to occur, with rates surging from 24.2 cases per 100,000 residents to 80.2 in 1990 before falling sharply to 5.9 in 1991. Even here, however, improvement over past decades could be noted because epidemics occurred only every four or five years as compared with the previous pattern of occurring every other year. Somewhat less progress was apparent in the campaign against tuberculosis, with rates declining from 16.1 cases per 100,000 residents in 1980 to 14.3 in 1990.

Vector-transmitted illnesses remain major public health challenges, especially in southern Mexico. Malaria increased dramatically from 36.9 cases per 100,000 residents in 1980 to 171.5 cases in 1985, before dropping to 31.1 in 1991. Chiapas, Oaxaca, Guerrero, Michoacán, and Sinaloa are priority areas for government antimalarial campaigns. After not a single case of onchocerciasis was reported in 1980 and 1985, the disease reemerged in the late 1980s. Health officials identified 2,905 cases in 1987 and 1,238 cases in 1991, most of them in Oaxaca and Chiapas. In contrast, significant progress occurred in the reduction of dengue, with cases per 100,000 residents declining from 73.8 in 1980 to 6.9 in 1991. The disease is found along the Gulf of Mexico and Pacific coastal regions, the mouth of the Río Balsas, and central Chiapas.

Although most sexually transmitted diseases declined throughout the 1980s, acquired immune deficiency syndrome (AIDS) proved a glaring and deadly exception. Mexico reported its first cases of AIDS in 1983. Both the total number of cases and the ratio increased annually through 1993. In 1993 the government reported 5,095 new cases, or 5.4 cases per 100,000 residents.
