This January, Rio de Janeiro reached the record number of hospitalizations for dengue in the city’s history. The information was given by the Secretary of Health, Daniel Soranz, during a press conference promoted by the city hall, this Friday, 2, to announce a contingency plan against the dengue epidemic experienced by the city.

According to Soranz, 362 people were hospitalized this month alone. Regarding the number of infected people, the secretary said that only in January did the number come close to that recorded in the previous year.

“We see the upper limit clearly marked, much higher than what we expected. And this constitutes an epidemic situation. We have an increase in the number of cases sustained in the historical series, with repercussions on patients’ clinics and the care network. It also constitutes an epidemic it is necessary for us to have the number of cases spread across more than one region of the city. And this happens in the city of Rio. In the last 90 days, the curve is upward, we have had, in a single day, 569 cases reported”, said Daniel Soranz.

Check out some dengue numbers in Rio below:

  • In January, there were more than 10 thousand cases of dengue in Rio de Janeiro;
  • The value represents an incidence rate of 160.68 per 100 thousand inhabitants;
  • Throughout 2023, there were 22,959 cases;
  • Across the country, the numbers are also high. There are 43.7 thousand registered cases, with 24 confirmed deaths and 163 under investigation.

The three states with the highest rates of occurrence are the Federal District, Minas Gerais and Acre. The state of Rio de Janeiro appears in seventh place, with 17,700 cases of the disease. The highest incidence is in the adult population, especially in the age groups of 30 to 39 years and 40 to 49.

Alert on: dengue cases spike in several states

Mayor Eduardo Paes asked for the population’s collaboration to reduce the outbreaks of dengue mosquitoes.

“The absolute majority of cases are caught at home or near the place where they live due to absolute carelessness due to the history of stagnant water. We are presenting the measures that we are going to take, but I make an emphatic appeal to the population that there is no point in just pointing out the finger the governments or blame the mosquito. We, as citizens, end up creating the environment conducive to the proliferation of dengue,” he said.

City hall measures

The city hall announced some strategies to combat dengue. Among them are:

  • Creation of the Emergency Operations Center (COE-Dengue);
  • Opening of ten service centers for the disease distributed throughout the municipality;
  • Dedication of beds for dengue patients in municipal hospitals;
  • Use of smoke cars in regions with the highest incidence of cases;
  • Compulsory entry into closed and abandoned properties.

Next Monday, the 5th, the first service center for dengue patients will be opened at CMS Raphael de Paula Souza, in Curicica, in the West Zone.

Dengue vaccine

Rio de Janeiro is part of the 521 municipalities that will receive and administer dengue vaccines through the Unified Health System (SUS). Immunization is scheduled to begin this February, as announced by the Ministry of Health.

There will still be a definition of the audience and priority regions. However, in the first phase of immunization, citizens from 16 states and the Federal District that have municipalities that meet the requirements for the immediate start of immunization will be vaccinated.

The states are:

  • Goiânia;
  • Bahia;
  • Acre;
  • Paraíba;
  • Large northern river;
  • Mato Grosso do Sul;
  • Amazon;
  • São Paulo;
  • Tocantins;
  • Roraima;
  • Holy Spirit;
  • Rio de Janeiro;
  • Paraná;
  • Minas Gerais;
  • Santa Catarina.

Initially, the Qdenga lots will be allocated to municipalities that have more than 100 thousand inhabitants and high rates of transmission of the disease in the last ten years. Qdenga, which will be applied by SUS, has been shown to be effective against three dengue serotypes: DENV-1 in 69.8% of cases; DENV-2 in 95.1%; and DENV-3 in 48.9%.

It was not possible to evaluate the effectiveness of the dengue vaccine for DENV-4, as there were few cases of dengue caused by this serotype. These data were released by the Brazilian Society of Immunizations (SBim).

Who can get the dengue vaccine?

In the first phase, the dengue vaccine will only be offered to children and adolescents aged 10 to 14. This group was chosen because this is the age group that presents the highest risk of worsening the disease.

However, Qdenga is recommended for people aged 4 to 60, from those who have already had dengue fever to those who have never been infected — unlike Dengvaxia, which is only recommended for people who have already been infected with the dengue virus.

Qdenga is not recommended for the following groups:

  • People over 60 years old;
  • Are you allergic to any of the components of the vaccine;
  • Has a compromised immune system;
  • Have an immunosuppressive condition;
  • Pregnant and breastfeeding women.

In the case of Dengvaxia, available only on the private network, it is also not recommended for people over 45 years of age.
