As of October 12 this year, there have been 689 dengue deaths nationwide, according to the latest Ministry of Health epidemiological bulletin, nearly 5.4 times higher than the 128 deaths reported in the same period in 2018.

In all, 1,489,457 million reported cases of dengue were reported in 2019 by 12 October, about 690% higher than the 215,585 cases in 2018. Dengue now has 708.8 per 100,000 inhabitants. The region with the highest incidence rate is the Midwest, with 1,235.8 for each group of 100,000 inhabitants, despite having a smaller number of cases.

The states of Minas Gerais (482,739), where there were 154 confirmed deaths, and São Paulo (442,014), with 247 confirmed deaths, concentrate 62% of the probable cases. In the Southeast, the incidence rate is 1,151.8 for each group of 100,000 inhabitants.

In the period, 2019 is the third year with the highest notification of dengue cases in Brazil since the beginning of the historical series in 1998, behind only 2015 (1.68 million) and 2016 (1.5 million).

Among the possible causes for the advance of dengue fever is the return of a serotype of the disease that had not circulated in Brazil for years, as highlighted yesterday (1) Health Minister Luiz Henrique Mandetta.

“We had serotype 2 reentry two years ago, and last year it did a lot of damage in the state of São Paulo, in the Bauru region. Then dengue re-entered Goiás, Tocantins – it was a very large number of cases, because serotype 2 had not circulated in Brazil for many years, so now it comes back in full force, ”said the minister.

Other factors that contribute to the return of Aedes aegypt mosquito-borne disease are concentrated in increased rainfall in some regions and also less prevention.

The ministry survey also gathers information on chikungunya fever. In all, the states already accounted, by October 12 this year, 123,407 cases, compared to 78,978 of the same period in 2018.

According to the ministry, the prevalence rate of infection, which is also transmitted by the mosquito Aedes aegypti, is much lower than dengue fever: 58.7 cases per 100,000 inhabitants. The states of Rio de Janeiro (83,079) and Rio Grande do Norte (12,206) concentrate 77.2% of the probable cases.

By the close of the balance sheet, 75 deaths from Chikungunya had been confirmed.

The epidemiological report also follows the situation of Zika. The survey, in this case, runs until September 21, when 10,441 reported cases of the disease were recorded. This year, the Zika virus was the cause of the death of three people.


To reduce the spread of disease-vector mosquitoes, the Ministry of Health advises the population to take preventive actions, such as checking if there is any kind of water deposit in the yard or indoors. Another recommendation is to wash weekly, with soap and water, containers such as pet water canisters and potted plants.

Not letting piles of rubbish or rubbish form in open places such as yards, squares, and vacant lots is another important point. Another habit that can make a difference is regular cleaning of the gutters, with proper removal of leaves that can accumulate during the winter.
