Ministry of Health confirms 89 deaths due to yellow fever

According to a new bulletin released by the Ministry of Health, Brazil has 89 confirmed deaths of yellow fever. Among them, 77 occurred in Minas Gerais, nine in Espírito Santo and three in São Paulo.

The agency received 1,258 suspected cases, most of them 1,032 in Minas. Of this total, 263 infections were confirmed, 882 still need investigation and 113 records were discarded. The state of Minas Gerais, Espírito Santo, São Paulo, Bahia, Tocantins, and Rio Grande do Norte continues to be investigated and confirmed.

This is an acute febrile infectious disease of short duration (maximum 10 days), and of varying severity. It has two cycles of transmission: the wild and the urban (eradicated in Brazil since 1942). The last outbreak of wild yellow fever in the State of São Paulo was in 2009, with 72 cases and nine deaths confirmed. Two deaths from the virus were also confirmed in 2008 and two more in 2002. According to the Ministry of Health, about 20% to 50% of people develop the disease in its most severe form, and can die. earlier this year, the Ministry of Health has sent extra doses of the yellow fever vaccine to states that are registering suspected cases of the disease, as well as others located in the border with areas that have reported cases. In total, 12.7 million extra doses were sent to five states: Minas Gerais (5.5 million), São Paulo (2.75 million), Espírito Santo (2.5 million), Rio de Janeiro million) and Bahia (900 thousand).

Causes

The transmission of the disease is not made directly from one person to another. For this, it is necessary that the mosquito prick an infected person and, after the yellow fever virus (belonging to the genus Flavivirus, family Flaviviridae) has multiplied (nine to 12 days), chop an individual who has not had the disease and has not been vaccinated. The virus and the clinical course of the disease are identical for cases of urban yellow fever and wild yellow fever, differentiating only the disease transmitter. Wild yellow fever occurs mainly through mosquitoes of the genus Haemagogus. Once infected in the wild, the person can, on his return, serve as a source of infection for the Aedes aegypti (also dengue vector), the main transmitter of urban yellow fever.

Prevention

The only way to avoid Yellow fever is vaccination. The yellow fever vaccine is free and available at health clinics at any time of the year. It is given as a single dose from 9 months of age and is valid for 10 years. Must be applied 10 days before travel to areas at risk of transmission of the disease. Aedes aegypti proliferates in the vicinity of dwellings, in containers that accumulate clean and still water. To prevent mosquitoes from proliferating, simple measures should be taken, such as placing sand in the plant cups, covering containers that collect water - trash cans, tires, water tanks, casks, removing water from slabs, unclogging gutters, storing glass or pet bottles , empty buckets and vessels and face down

Treatment of yellow fever

There is no drug to combat the yellow fever virus. Treatment is only symptomatic and requires care in patient care, which, when hospitalized, should remain at rest with fluid replacement and blood loss when indicated. In severe forms, the patient should be treated in an Intensive Care Unit.


Soft drinks: a problem for the teeth

Soft drinks: a problem for the teeth

Soft drinks stand out as one of the most important sources of dental caries in the diet, reaching people of all ages. Acids and acidic byproducts of sugar present in soft drinks demineralize the tooth enamel, contributing to the formation of caries. In extreme cases, demineralized enamel combined with inadequate brushing, bruxism (grinding habit) or other factors can lead to tooth loss.
