Mystery illness remains undiscovered by Minas authorities after 24 days
The small town of São Francisco in Minas Gerais, Brazil, is currently under investigation after reports of a mysterious disease outbreak. At least two people have lost their lives, and another 20 have shown symptoms of respiratory and hemorrhagic issues.
Authorities are taking immediate action to contain the outbreak, intensifying measures such as active case finding, sample collection, and contact monitoring. The public is advised to avoid close contact with sick people and to use masks if they have flu-like symptoms or when visiting healthcare units.
While the exact nature of the disease remains unknown, clinical samples are being examined to confirm the etiology and rule out other diagnostic hypotheses. So far, no cases of hantavirus, leptospirosis, or bacterial meningitis have been detected. Laboratory results for influenza, rhinovirus, parainfluenza type 4, and respiratory syncytial virus have been detected and are being considered in the ongoing analysis.
The first cases were reported after social events on June 23, 24, and 27 in both rural and urban areas. The outbreak has been classified as an Event of Importance to Public Health (EISP). The public is also advised to avoid crowds and poorly ventilated places, especially if they have respiratory symptoms.
In light of the ongoing investigation, the State Health Secretariat of Minas Gerais (SES-MG) is conducting investigations through the Strategic Information Center for Health Surveillance (CIEVS Minas). The investigations are being carried out in partnership with the Ministry of Health, through the Advanced Training Program in Epidemiology Applied to Services of the Unified Health System (Episus Advanced).
The mystery disease in São Francisco is not the first health challenge Minas Gerais has faced. The region has experienced significant cases of Chikungunya, another mosquito-borne disease, since 2014. During the Chikungunya epidemic in Minas Gerais in 2023, there were 890 excess deaths attributed to the disease, resulting in a mortality rate of 35.1 per 100,000 inhabitants.
Chikungunya is caused by the Chikungunya virus, transmitted primarily through the bite of infected mosquitoes. The disease is characterized by symptoms like fever, joint pain, and swelling, and can lead to severe complications.
Ongoing research and investigations are directed towards understanding and controlling vector-borne diseases. The newly established Center for Advanced and Innovative Therapies at the Universidade Federal de Minas Gerais (UFMG) as part of the Global Virus Network may contribute to ongoing efforts to study and combat these diseases. Additionally, studies on Dengue in Brazil highlight the importance of integrating epidemiological and climate data to optimize preventive strategies, which could be applied to other vector-borne diseases.
In the meantime, the public is advised to cover their nose and mouth with their arm or disposable tissue when coughing or sneezing, keep their flu vaccination up to date, especially for priority groups, and seek medical attention if they experience symptoms such as fever, cough, body aches, difficulty breathing, or bleeding.
As the investigation continues, the people of São Francisco and Minas Gerais await answers and solutions to this mysterious disease outbreak. The local health authorities and scientific research networks are working tirelessly to identify the cause and find a way to stop the spread of the disease.
