By increasing the number of dengue 2 serotypes in countries such as São Paulo and Rio de Janeiro, health authorities in Rio Grande do Norte have strengthened recommendations for network doctors to require isolation of the dengue virus. in order to determine the possible entry of this virus typing into the country. So far, the authorities have said that there is only a serotype 1 that has been circulating in Brazil for a long time.

At present, only the serotype 1 denge circulates in the RN, but a warning is returned to 2, with records in Rio de Janeiro and Sao Paulo to reach the state

According to the latest epidemiological bulletin issued by the State Secretariat for Public Health (Sesap), 2019 represents a significantly smaller number of cases reported and confirmed than in 2018. In 2727 cases, suspected cases of dengue were reported in 2019, of which 624 confirmed. Of these, 18 were treated as dengue "with warning signs", the other being "severe denga", according to the bulletin.

In 2018, out of 4682 reported cases, 1,509 cases were confirmed in the first 13 weeks of the year, which is 41% more than this year. During the confirmations, there were 49 "denga with alarm signals" and 5 "heavy denge". Dengue definitions with alarm signs and severe dengue are defined on the basis of the symptoms of each patient.

There are 5 identified dengue serotypes in the world that circulate around the world. Of these, four are driving in Brazil, and one in Malaysia alone. Serotype 2, explains Kléber Luz, who infects a doctor, eventually circulates from time to time. "Type 2 always returns, year after year is again isolated. An increase in the number of cases in the southeast warns you because it can represent this return," he explains.

Although the symptoms of serotype 1 and 2 do not differ, the so-called "sequential infection" is the one that can pose a greater risk to a patient who has had a dengue earlier, says the doctor. "It does not have to be more aggressive, but it usually happens that this will happen, and this will show this function, especially if it is present in a consecutive form of infection," he says.

Dengue infection causes permanent resistance to contract serotypes. The sequential infection theory explains that, to the extent that antibodies obtained – active or passive – prevent re-infection with the same serotype of the disease that promotes their production, they also facilitate the infection of other serotypes and may impair their symptoms.

The time when it is possible to isolate the virus to accurately identify the serotype of the dengue or even the arbovirosis that the person has received is short. This should be done preferably within 5 days after the onset of symptoms. After 10 days, the virus becomes impossible to identify.

Other arboviruses present in RN

In the epidemiological bulletin, besides dengue, data for chikungunya and zico in the country are also included – both diseases were reduced in the number of applications and confirmation compared to the same period in 2018.

In 2019, 297 cases of chikungunya were reported, of which 98 were confirmed. There were no reported or registered deaths in the country due to illness. In 2018, 647 reports were made up to the 13th epidemiological week, of which 127 confirmed cases of disease. During this period, 19 deaths were reported, of which 2 were confirmed as a consequence of chikungunya.

Zika has not yet submitted confirmed cases this year, despite 54 notifications. In 2018 there were 209 notifications, the highest incidence in the municipality of Jucurut, in the 4th region of health, out of 209, 22 were confirmed.

Figures

624 This year, cases of dengue threat were confirmed, with 18 alarm signs.

1.509 Dengue fever cases were confirmed in the RN last year over the same period.

41% is the rate of decline of confirmed cases between two years in the US. t 13 first weeks.

98 Chikungunya cases were confirmed this year 290 notifications.

54 suspect Zika were informed this year, although no confirmation has yet been made.
