At a time when the rains are returning in most of the country, concerns are growing about the proliferation of the Aedes aegypti mosquito, which transmits dengue, Zika and chikungunya.

Therefore, the Ministry of Health advises that to prevent diseases transmitted by the insect, it is essential to avoid the accumulation of stagnant water, where the proliferation of the mosquito occurs.

The period of the year with the highest transmission is the wettest months in each region, but it is important to maintain hygiene and avoid standing water every day, because Aedes aegypti eggs can survive for a year until they find the best conditions to develop.

Therefore, it is important to check that there is no standing water in tires, plant pots, bottles and other containers that may allow the mosquito to reproduce.

“It is important to remember to cover the water tanks, keep the gutters clean, leave bottles and containers upside down, weekly clean and fill the potted plant dishes with sand, keep trash cans well covered, drains clean, with application of screens, in addition to keeping tarpaulins for construction material and swimming pools always stretched so as not to accumulate water.

They are extremely simple measures, in a quick 15-minute scan, you can prevent the proliferation of the mosquito and do your part in the fight against dengue fever”, emphasizes the Secretary of Health Surveillance Arnaldo de Medeiros.

The Ministry of Health maintains continuous surveillance in the country throughout the year to prevent the proliferation of Aedes aegypti with research structures, use of insecticides and the action of health agents, among others.

With the escalation of health issues caused by Covid-19, inspections of people’s homes were suspended, but they are now returning.

“With the advance of vaccination and the considerable reduction in hospitalization by Covi-19, agents to combat endemic diseases and community agents are resuming visits, observing all the recommendations of the health agencies so that this resumption is safe for all”, concluded the Secretary of Health Surveillance Arnaldo de Medeiros.

Symptoms and Treatment

There are four types of dengue virus – serotypes 1, 2, 3 and 4. High fever is one of the main symptoms of the disease.

Others are severe muscle pain, pain when moving the eyes, malaise, lack of appetite, headache and red spots on the body.

Dengue infection may also cause no symptoms, be mild or severe. In the latter case, it can even lead to death.

Older people are at greater risk of developing severe dengue and other complications that can lead to death.

The risk increases when the person has a chronic illness, such as diabetes and hypertension.

There is no specific treatment for dengue. According to the medical evaluation, measures such as resting, drinking plenty of water and not taking medications on their own are recommended. Hydration with serum in the veins may also be recommended.

In case of suspicion, it is essential to seek a health professional to have the correct diagnosis.

Zika and chikungunya have dengue-like symptoms such as fever, headache, malaise, body aches and a lot of joint pain.

Treatment is also based on symptoms.

In the case of chikungunya, some people can develop a post-acute, chronic condition with joint pain that lasts for months or years.


According to the Ministry of Health, from January 3 to October 9, 2021, from the 1st to the 40th epidemiological week, the country registered 479,745 cases of dengue, a reduction of 47.7% compared to the same period last year.

In this same interval, 199 deaths from dengue were confirmed, a reduction of 64% compared to 2020.
