Dengue and Zika showed a significant setback in Yucatan, during 2018, to the point of establishing historical records. However, a health department report highlighted the reappearance of Chikungunya, an illness that has been absent for more than two years.

Likewise, it was demonstrated that these diseases that are present in the State are transmitted by three vectors, the Aedes aegypti, the Aedes albopictus, better known as “tiger mosquito”, and Culex quiquefasciatus mosquitoes.

According to the federal Ministry of Health, the significant decrease in dengue was a remarkable success, demonstrating that this condition can be controlled.

Likewise, Yucatan was set as an example, since the pathology was absent for nine months, that is, it was until the first week of October when the first two cases were confirmed.

At the end of the year, 19 confirmed cases were registered in the State, with a decrease of 83.2 percent with respect to 2017, when the figure went up to 113 cases.

According to the statistics provided, this is the lowest figure from 2011 to the date, the highest incidence was in 2011, with 194 cases.

At the regional level, Quintana Roo is the most affected state in the Peninsula, with 204 cases, which is why it ranks eighth in the national incidence table, representing 1.6 percent of the national total.

Yucatán is number 23, with 0.15 percent of the total registered in the Mexican Republic, while in Campeche is among the five states in which no cases have been registered.


As for Zika, the same phenomenon of decrease occurred, because at the end of the year only 26 cases were recorded, the lowest amount of the three-year period.

After the appearance of this exotic disease that became endemic, there were already 1,325 registered cases (1,189 casess  in 2016 alone), there was a significant decrease in 2017, a year that registered only 110 cases. That is, 76.4 percent less than the previous year.

In Quintana Roo there were two cases, while in Campeche, along with 12 other states, the balance was zero cases.


After a two-year truce, Chikungunya reappeared in the State, an imported disease that also became endemic.

Four years after the prevalence of this pathology, in the state 1,683 cases were confirmed, and from the first year of its appearance, the incidence decreased significantly.

Only in 2015 1,669 were infected, the following year it reached 11 cases, none in 2017, but in 2018 there were three, all of them, male.

Last year, the disease only appeared in 11 states, and in Yucatán, as well as in Michoacán and Veracruz, only three cases were recorded, 7.7 percent of the national total, respectively.

In the first week of September 2016 the last case was recorded in Yucatan, until the first two of the year were confirmed in mid-October of 2018, and three weeks later, the third.
