After identifying more than 1,000 dengue foci, Blumenau epidemiological surveillance issues an alert

On Wednesday 16, the Epidemiological Surveillance Service of the Blumenau Health Promotion Department (Semus) issued a warning note for health units in primary care. The announcement was made due to the increase in the number of dengue fever cases recorded in the commune.

From January to today, officers have identified 1,608 outbreaks of the Aedes aegypti mosquito, responsible for transmitting dengue fever, yellow fever, zika and chikungunya. During the same period last year, there were 1,177 outbreaks, representing a 35% increase over the period.

Confirmed cases

To date, the municipality has registered 269 notifications. Of these, 65 are confirmed cases, with six imported cases and 59 autochthonous, that is to say contracted in Blumenau.

Two inhabitants of Blumenau diagnosed with dengue fever are hospitalized in the city’s hospitals. On March 7, a 33-year-old woman was diagnosed with the disease. On March 9, a 35-year-old man was diagnosed with the disease. The two patients are hospitalized in a ward, in a stable state of health.

Currently, of the 35 neighborhoods in the city, 17 are considered infested and are being monitored daily. They are: Água Verde, Centro, Do Salto, Escola Agrícola, Garcia, Fortaleza, Itoupavazinha, Itoupava Norte, Itoupava Seca, Jardim Blumenau, Ponta Aguda, Salto do Norte, Tribess, Velha, Velha Central, Vila Nova and Victor Konder.

The Escola Agrícola district concentrates 50% of the contamination sites in the municipality. However, transmission also occurs in the neighborhoods of Garcia, Velha Itoupava Norte, Água Verde and Vila Nova.

Elimination of mosquito epidemics

In January, endemic disease agents stepped up the application of Ultra Low Volume (ULV), popularly known as smoke, in neighborhoods where there is a combination of two factors – the presence of the infected mosquito and the patient with a confirmed diagnosis.

Dressed in a specific uniform that guarantees the safety of professionals, they apply a “cloud” of smoke with a low dose of a pesticide that eliminates most adult mosquitoes. The action is recommended by the National Epidemiological Surveillance Council (DIVE) in the fight against the Aedes aegypti mosquito.

The municipality’s dengue program has about 60 professionals who work in the supervision and guidance of residents. The agents are identified by a uniform and a badge with the name and registration of the professional hired by the city of Blumenau. Photos of all agents are available at Town hall website.

Signals and Symptoms

The first manifestation of dengue is a high fever (39° to 40°C) of sudden onset, which lasts from two to seven days, associated with headaches, weakness, body, joint and back pain. .

In addition, spots on the body are present in 50% of cases, and can affect the face, trunk, arms and legs. Loss of appetite, nausea and vomiting may also be present.

People who show symptoms of the disease must seek treatment in the units of the Family Health Strategy (ESF) or the General Ambulatory (AG). Seeking care in the event of suspicion helps to avoid the aggravation of the condition and even the evolution towards death.

denunciations

The population can also report places where there are possible mosquito outbreaks, by contacting the dengue fever program, via OuvidorSUS on telephone 156 (option 4) or by telephone 3381-7770.

Tips and precautions to prevent the proliferation of Aedes aegypti:

– Remove standing water from all containers

– Leave the water tanks always sealed, without any openings, especially the water tanks
– Plants such as bromeliads should be avoided as they accumulate water
– Treat the pool water with chlorine and clean it once a week
– Keep drains covered with daughter mesh screens to prevent mosquitoes from entering the site
– Wash containers with water deposits, such as pet food and water jars, with a brush or sponge and detergent, at least once a week
– If it is necessary for the container to be filled with water, as in the case of drains, use hypochlorite
– Remove the water accumulated on the slabs
– Flush at least once a week in little used toilets
