Brazil recorded 757,068 suspected dengue fever cases in the first 18 weeks, representing a 151% increase from the same period in 2021. The country has an incidence of 354.9 cases per 100,000 people, according to the epidemiological bulletin of the Ministry of Health. released this Monday (16).

Dengue fever information refers to reports occurring between epidemiological weeks (ES) 1 and 18 (January 2 to May 7), available on the online Notifiable Diseases Information System (Sinan).

Among the entities of the federation with the highest incidence of the disease are the Federal District, with 37,856 cases, Goiânia (GO), with approximately 36,000 cases, Joinville, with 11,373 cases, Palmas, with 10,523 cases and Aparecida de Goiânia/GO, with 10,346 cases. case.

Until SE 18, 504 cases of severe dengue (DG) and 6,730 cases of dengue with warning signs (DSA) have been confirmed. Another 524 cases of GD and ASD are still under investigation. So far, 265 dengue deaths have been confirmed, 241 by laboratory criteria and 24 by clinical epidemiological criteria.

The states with the highest number of dengue deaths were São Paulo (99), Santa Catarina (28), Goiás (28) and Bahia (22). Another 300 deaths are under investigation.


Based on reports between epidemiological weeks (ES) 1 and 18 (January 2 to May 7), the ministry estimates that there were 70,092 probable cases of Chikungunya, with an incidence rate of 32.9 cases per 100,000 people in the country. . These figures correspond to a 74.6% increase in cases compared to the previous year.

Among the municipalities with the highest records of probable cases of the disease are Juazeiro do Norte (CE), with 4,027 cases, Fortaleza (CE), with 3,615 cases, Salgueiro (PE), with 2,462 cases, Crato ( CE), with 2,457 cases. and Barbalha (CE), with 1,926 cases.

The Northeast region concentrates the majority of cases (97.6 cases/100,000 inhab.), followed by the Midwest (21 cases/100,000 inhab.) and the North (14.2 cases/100,000 inhab.).

The record has already confirmed 14 deaths from the disease, nine in Ceará, two in Paraíba, one in Maranhão, one in Alagoas and one in Mato Grosso do Sul. 16 other deaths are under investigation.


The country had 5,787 probable cases of Zika through SE 17 (January 2 to April 30), corresponding to an incidence rate of 2.7 cases per 100,000 population. Compared to 2021, the data represents a 214.5% increase in the number of cases in the country. During the observed period, no deaths due to the disease were recorded.

mosquito breeding

The Rapid Index Survey of Aedes aegypti (LIRAa), carried out by the Ministry of Health, indicated that 42% of dengue mosquito breeding sites are in reservoirs of water intended for human consumption. . These figures reinforce the importance of the participation of the population in the fight against the proliferation of Aedes aegypti, the mosquito being more and more accustomed to the domestic environment.

The survey also highlighted that mobile, fixed and natural depots appear as the second breeding ground for mosquitoes, with 32%, while garbage depots have an incidence of 25%.

With high temperatures and rainy seasons, the number of breeding sites is expected to increase. Therefore, the Department of Health suggests people set aside at least 10 minutes a week to inspect their homes. It is necessary to check the roof, clogged gutters, swimming pool, bottles, tires and other objects that could become the breeding grounds of the transmitter. The leaflet warns that water tanks should not be left uncovered.

Among the main measures that people must take to eliminate breeding sites is washing barrels with soap and water, as well as gallons or water tanks, which must be closed. In addition, it is necessary to keep the water tanks tightly closed; cleaning and removing leaves from gutters; remove accumulated water from the slabs; unclog drains and keep them closed or screened; put sand or putty on broken glass walls; wash plants that accumulate water twice a week; fill hollows in trees and bamboos with sawdust, cement or sand; avoid using dishes on the plants or keeping them with sand to the brim.

The population must also treat the pool water with chlorine and clean it once a week; remove the water and wash the outer shelf of the refrigerator with soap; wash the support of the mineral water bottles at each change; wash animal bowls with a sponge or loofah, soap and running water, change them once a week; keep fish tanks clean and covered or screened; keep toilets clean and lids tightly closed; store empty bottles and buckets upside down; throw away objects likely to accumulate water, such as: cans, bottle caps, eggshells, disposable cups; always keep garbage cans well covered and plastic bags tightly closed; drill holes in the bottom of the outer bins; discard or recycle old tires or puncture them and store them in dry, covered places.

The Ministry of Health recommends that anyone who has dengue fever symptoms, such as fever, headaches and body aches, go to the nearest health center to their home for treatment.


To provide protection against the mosquito vector of arboviruses, the Ministry of Health sends biolarvicide to states and municipalities, depending on the local epidemiological situation and demand. The product represents an effective alternative in the control of mosquito larvae, as it can be added wherever water collects and has the potential to be a breeding ground for insects.

The new technology guarantees a lower environmental impact, since it is a biological product with a low impact on human health. The treatment of certain breeding sites with the biolarvicide must be considered complementary and target deposits that cannot be eliminated or managed in any other way, mechanical control always being the first alternative.

The great advantage, compared to traditional insecticides, is that the biological product only kills mosquito larvae, without affecting people or pets, including fish, birds and other beneficial insects. It also does not affect the environment, since it is neither cumulative nor polluting.
