The Ministry of Health and the State Department of Health of Rio de Janeiro have, by a note, excluded the presence of the bacterium Yersinia pestis, responsible for bubonic plague, in a 57-year-old patient hospitalized at Luiz Palmier Municipal Hospital (HLP), São Gonçalo. The diagnosis was made after the Central Public Health Laboratory (LACEN) of the State of Rio de Janeiro badyzed again the previous HLP, which was checking for the presence of the bacteria.
In the LACEN report, the presence of another bacterium, Morganella. morganni, considered common and widely distributed in the environment. According to the note, it can cause infection of wounds, respiratory tract and urine in people whose immune system is compromised. However, this is generally not a problem for people with good immunity.
Laboratory samples were always collected and sent to the Research Institute Aggeu Magalhães-FIOCRUZ-PE to deepen and close the investigation into the case. Nevertheless, the possibility that the patient is diagnosed with bubonic plague can already be ruled out, so it is no longer advisable to remain in isolation.
The complete note of the Ministry of Health:
The Ministry of Health states that the case in the municipality of São Gonçalo (RJ) has not been confirmed for bubonic plague. The case does not fit the suspect case definition, that is, the clinical presentation presented by the patient does not meet the suspect case definition of bubonic plague. The Central Public Health Laboratory (LACEN) of the State of Rio de Janeiro reviewed the badysis and identified the bacterium Morganella morganni, an opportunistic bacterium widespread in the environment and in humans . It is a microorganism widespread in the environment and does not cause infections in individuals with good immunity.
Laboratory samples were collected and expected to arrive on Monday (14) at the Aggeu Research Institute Magalhães-FIOCRUZ-PE reference laboratory for further badysis and closing of the investigation. It is important to emphasize that, if the alleged (previously rejected) plague is maintained, it is not necessary to isolate the patient because it has been treated with a drug and, in this way, it is not necessary to There is no risk of transmission.
The Ministry of Health informs that the last case of bubonic plague recorded in Brazil occurred in the state of Ceará in 2005 and evolved to heal.
Plague is an acute infectious disease transmitted primarily by infected flea bites. The etiological agent is a Gram-negative bacteria – Yersinia pestis. The disease has three clinical forms, namely bubonic plague, pneumonic plague, and septicaemic plague. Due to the persistence of infection in wild rodents, the disease represents a potential danger to the populations.
The only form of prevention is to avoid contact with wild and synanthropic rodents (living in urban areas) and with their fleas. The bubonic form is the most common and, among other manifestations, the disease causes high fever, chills, intense headache, lack of appetite, vomiting, confusion and red eyes (congestion of conjunctiva). Antibiotic treatment is offered in the Unified Health System – SUS and, to be effective, it must be started within 15 hours of the onset of symptoms. The Secretary of State for Health (SES) informs that the examination of the bacterium Yersinia pestis was negative, causing bubonic plague, at Luiz Palmier Hospital. The test revealed only the presence of a single bacterium, common in skin lesions. For the performance of the blood test carried out by the central laboratory Noel Nutels (LACEM), the techniques recommended by the national reference laboratory of Fiocruz / MS have been adopted. [196459002] What is the disease – Bubonic plague, or black plague, has spread worldwide in the 1300s to the Middle Ages and killed about 100 million people between the 39th and the 18th centuries. Europe and Asia. It is caused by the bacteria Yersinia pestis and transmitted by fleas as well as by the inhalation of respiratory droplets in the pneumonic forms.
