Dengue fever cases increase by 28% in Paraná and the secretary reveals answers to doubts

Elimination of the dengue mosquito is essential, as is information about the disease, how it is acquired and how to avoid its transmission. Activities with endemic control agents, data collection, field work by specialized teams, educational actions with the population, qualification and training of servers and health agents are behaviors that mobilize the public health system. However, public participation is essential for the elimination of mosquito breeding sites, since most are located on land and houses.

In this context, so that everyone can contribute to the fight against dengue, the Department of State for Health (Sesa) takes questions and answers questions related to the disease. Currently, Paraná has 150,752 reported cases, with 56,191 confirmations. There are 12,440 more cases, an increase of 28.43% compared to the figures of the previous report. The data comes from the 38th epidemiological report, of the new seasonal period of the disease, which began on August 1 and is expected to continue until July 2022, published on Tuesday (17).

Of the 380 municipalities that have registered dengue fever notifications, 328 have confirmed the disease, and in 286 of them they are autochthonous cases, that is, dengue fever was contracted in the municipality residence of the patient. Sesa’s weekly dengue bulletin reports the deaths of nine more people. The disease has already caused 21 deaths across the state since the start of the epidemiological period.

Doubts and some myths about dengue can help prevent new cases:

How do you recognize the Aedes aegypti mosquito?

The mosquito has: dark body, with white stripes on the trunk, head and legs and has a habit of biting, mainly during the day.

How can people help?

Avoid the presence of breeding sites, both at home and in the place of work and study, by properly disposing of garbage, waste and recyclable materials. The elimination of any container that can accumulate water is essential to prevent mosquito breeding.

What are the most common dengue mosquito breeding sites?

Tires, gutters, vases, flat vases, bottles, water tanks without lids or with broken lids, cans, canvas or plastic, drains, bromeliads, swimming pools without treatment, disused toilets, cisterns without adequate sealing and containers that can accumulate water.

Can an infected person transmit the disease to another?

There is no transmission by direct contact of a patient or his secretions. The person is also not contaminated by the sources of water, food or the use of personal objects of the dengue patient. Transmission occurs only through the bite of an infected mosquito.

What are the main symptoms of dengue fever?

High fever (above 38.5 ºC), severe muscle pain, pain when moving the eyes, malaise, lack of appetite, headache and red spots on the body. Other more serious symptoms such as severe abdominal pain, persistent vomiting, dizziness (hypotension), decreased urine output and severe fatigue may also occur.

How long do the symptoms appear?

From three to fifteen days after the bite of the infected mosquito.

How to distinguish dengue fever from other febrile illnesses such as influenza?

The two conditions are similar because both have among the possible symptoms of fever, headache and in the rest of the body, fatigue and malaise. But dengue does not have respiratory symptoms such as a runny nose (runny nose), nasal obstruction (stuffy nose) or cough. The patient must avoid trivializing febrile cases and as soon as symptoms appear, consult a doctor.

When should you see a doctor?

It is necessary to consult a doctor whenever there is a manifestation of any kind of signs or symptoms.

Why are some drugs contraindicated in dengue fever?

Medications derived from acetylsalicylic acid (ASA) are totally contraindicated in all or suspected cases of dengue because they interfere with platelet function and thus increase the risk of bleeding and hemorrhage. Anti-inflammatories can produce digestive bleeding in predisposed patients. People who use chronic medication must report this situation during the medical appointment for a readjustment if necessary (AAS for children, anticoagulants, among others). Avoid self-medication.

Why do some people develop the severe form of dengue and others do not?

Dengue is not a trivial disease and immobilizes the patient for several days. Most cases progress to recovery, but some people can progress to severe forms of the disease and this can occur due to individual predispositions, especially those with other comorbidities, children, the elderly and women pregnant. And even if the person contracts or becomes infected with another serotype.

Can cases of dengue fever occur during the winter months?

Yes, as long as favorable conditions for vector proliferation are maintained. Even under low temperature conditions, mosquito eggs remain viable in breeding sites for about a year, hatching as soon as environmental conditions are favorable. It is therefore important to carry out the work to remove all containers that can accumulate water, even in winter.

Does putting bleach in the water help prevent larvae?

Not. The only way to prevent the proliferation of the mosquito is the removal and removal of water deposits. .

How is dengue fever diagnosed?

The diagnosis is based on a medical evaluation, based on the clinical examination of the patient and the epidemiological link. Additional tests, such as complete blood counts, may be done to identify disease severity and stage dengue fever. The tests are indicated to monitor the epidemiological situation in Paraná and carried out in patients classified as having warning signs and severe dengue fever. They are sent by the Ministry of Health and are also available for pregnant women and for suspected dengue deaths – 100% of examinations are guaranteed in these cases, for the criterion of surveillance of the disease in the state.

In what cases is the so-called “smoke” made?

The use of “smoke” is carried out as a last resort to control the vector and has a complementary character to other control actions, due to its limited scope and its great environmental impact. It should only be used in emergency operations to try to contain outbreaks or epidemics.
