Dengue virus during pregnancy may double the chance of stillbirth to die

Dengue virus during pregnancy may double the chance of stillbirth to die

To perform the study, a registry analysis of different (Sinasc), Mortality Information System (SIM) and National System of Notification Diseases (Sinan).

The researchers then compared data from 162,000 stillbirths and 1.5 million live births, of which 275 stillbirths and 1507 live births had been exposed to dengue.

The mechanisms by which dengue would cause the birth of stillbirths is unknown, but the researchers point out three hypotheses to explain the phenomenon : the symptoms of dengue would directly affect the fetus; dengue would cause changes in the placenta; or the virus itself would have a direct effect on the baby being born.

Although, since the 1980s, Brazil underwent systematic epidemics of dengue, the disease was considered lethal only when it reached its hemorrhagic form, which aggravated the infected and could lead to death. However, with the epidemic of congenital anomalies associated with zika in 2015, scientific research turned to the effects of viral infections during pregnancy.

How to prevent dengue

Avoid water accumulation

O mosquito lays its eggs in clean water, but not necessarily drinking. That's why it's important to throw away old tires, turn bottles upside down, and if the yard is prone to puddles, drain the land. It is also necessary to wash the water tank regularly and keep enclosures of water tanks and cisterns.

Place screen on windows

Placing screens on doors and windows helps protect your family from the mosquito dengue. The problem is when the breeding place is located inside the residence. In that case, the strategy will not succeed. Therefore, do not forget that the elimination of disease outbreaks is the most effective way to protect.

Put sand in pots of plants

The use of dishes in potted plants can generate water accumulation. There are three alternatives: eliminate this dish, wash it regularly or put sand. The sand preserves moisture and at the same time keeps the dish from becoming a mosquito breeding ground.

Be aware of your garbage

Do not dump garbage into ditches, ditches, banks of streams and streams. This ensures that they will remain clear, avoiding accumulation and even flooding. At home, leave the trash cans always well capped.

Put disinfectant in the drains

Small drains in kitchens and toilets rarely become a focus of dengue due to the constant use of chemicals such as shampoo, soap and bleach . However, some drains are shallow and retain stagnant water inside. In this case, ideally it should be closed with a screen or sanitized with disinfectant regularly.

Clean the gutters

Large reservoirs, such as water tanks, are the most productive breeding grounds for dengue, but the larvae of the mosquito can be found in small amounts of water as well. To avoid even these small puddles, gutters and pipes should be checked every month, as a slight clogging can create ideal reservoirs for the development of Aedes aegypti.

Pools and aquariums

Pools can become the focus of dengue - so attention should be redoubled with cleaning in times of outbreak. In the case of aquariums, fish are great predators of aquatic forms of mosquitoes.

Can pregnant women take dengue vaccine?

Pregnant women are contraindicated to take the dengue vaccine because it is a vaccine with attenuated virus, or (even if theoretical) to cause illness in people with the poorest immune system, such as the fetus.

Dilated cardiomyopathy: Excessive tiredness is the main symptom

After a light walk, Cadu tells his son that "he feels like he has raised the sugar loaf." As in most novels today, the insertion of some special group is very important for public awareness. The character created by Manoel Carlos in the novel "In the Family" shows signs and symptoms of a problem that was responsible for 231,964 hospitalizations in Brazil in 2013.

With low inventories, Ministry of Health calls population to donate blood

With low inventories, Ministry of Health calls population to donate blood

In Brazil, about 3.4 million blood donations are made per year. Data from 2016 indicate that 1.6% of the Brazilian population - 16 per thousand inhabitants - donates blood. Although the percentage is within the parameters of the World Health Organization (WHO)? of at least 1% of the population? the Ministry of Health has been struggling to increase the rate.
