The advice of the Health Department of the Association of Municipalities of Mineira (AMM) alerts public managers and the entire population to the dangers of the proliferation of cases in Minas Gerais.

The population is focusing its efforts on the fight against the coronavirus, but cannot forget to take care to prevent the proliferation of the Aedes aegypti mosquito, which transmits Dengue, Chikungunya and Zika, as hospitalization cases may increase, causing health system problems.

Dengue fever

In Brazil, dengue fever was first identified in 1986. The main form of transmission is the bite of the Aedes aegypti mosquito. There are records of vertical transmission (pregnant woman – baby) and blood transfusion. Dengue infection can be asymptomatic, mild, or cause severe illness resulting in death. Usually, the first manifestation of dengue is a high fever (39° to 40°C), of sudden onset, which generally lasts from 2 to 7 days, accompanied by headaches, body and joint pains, prostration, weakness, pain behind the eyes, skin rashes and itching.


Chikungunya fever is a disease transmitted by Aedes aegypti and Aedes albopictus mosquitoes. The main symptoms are a high fever of rapid onset, severe pain in the joints of the feet and hands, in addition to the fingers, ankles and wrists. There may also be headaches, muscle aches, and red spots on the skin. Symptoms begin between two and twelve days after the mosquito bite. About 30% of cases have no symptoms.


Zika was first identified in Brazil in April 2015. The main symptoms are headache, mild fever, mild joint pain, red spots on the skin, itching and redness of the eyes. Other less common symptoms are body swelling, sore throat, cough and vomiting.


In case of symptoms, it is important to consult a health service. Control actions mainly take place at the municipal level. When the outbreak of the mosquito is detected and it cannot be eliminated by the inhabitants of a certain place, the municipal health department should be called.

And the population can help by fighting mosquito epidemics. What to do:

  • Cover water tanks and reservoirs.
  • Keep gutters clean at all times.
  • Always leave bottles upside down.
  • Keep bins well covered.
  • Leave drains clean and screened.
  • Clean weekly or fill pots of potted plants with sand.
  • Clean pet water pots with a brush or loofah.
  • Remove accumulated water from the service area behind the washing machine.
