Municipal health departments in Jundiaí and Juiz de Fora have launched intensive testing and vaccination campaigns throughout July, marking the national “Julho Amarelo” (Yellow July) initiative. These efforts aim to increase public awareness, encourage early diagnosis, and promote the prevention of viral hepatitis, which officials identify as a significant public health challenge due to the often-silent nature of the diseases.
The Silent Threat of Viral Hepatitis
Viral hepatitis infections, which cause inflammation of the liver, can range from mild conditions to severe complications such as cirrhosis and liver cancer. According to health officials, a major obstacle in combating these infections is that they often evolve without symptoms for years, leading many individuals to discover the disease only after the liver has already been compromised. Data from the Ministry of Health’s 2025 Epidemiological Bulletin indicates that Brazil registered over 826,000 confirmed cases of viral hepatitis between 2000 and 2024. Hepatitis C accounted for 41.5% of these diagnoses, followed by Hepatitis B at 36.6%. Experts emphasize that early identification is the most critical factor for successful treatment and the prevention of long-term health decline.

Strategic Testing Initiatives
In Jundiaí, the Municipal Secretariat for Health Promotion and the Municipal Program for STI, HIV/AIDS, and Viral Hepatitis are coordinating free testing and orientation sessions at various locations. Scheduled events include: * Friday, July 17: UBS Pitangueiras (8h to 15h) and UBS Tamoio (14h to 16h). * Saturday, July 18: The Testing and Counseling Center (CTA) and the Integrated Health Center (NIS) from 8h30 to 11h. In Juiz de Fora, a “Day D” event is scheduled for Saturday, July 18, at the Center for Health Surveillance (Avenida dos Andradas, 523). From 8h to 15h, the facility will provide free, confidential rapid tests for Hepatitis B and C, as well as syphilis and HIV. No prior appointment is required, though participants must present an official photo ID.
Transmission and Practical Prevention
Health authorities highlight that different hepatitis viruses have distinct methods of transmission. Hepatitis A and E are primarily transmitted via the fecal-oral route, often through contaminated water or food and poor hygiene. Conversely, Hepatitis B, C, and D are linked to contact with infected blood, shared needles, or unprotected sexual activity. The Hepatitis D virus only manifests in individuals already infected with Hepatitis B. To mitigate risks, experts advise the following preventative measures: * Hygiene: Frequent hand washing and consumption of treated water. * Personal Items: Do not share items that can cause small cuts or contact with blood, such as nail clippers and razor blades. * Professional Services: Ensure that procedures like tattoos and piercings are performed in regulated establishments that utilize sterilized or disposable materials. * Protection: Use condoms during sexual intercourse. * Vaccination: The SUS offers free vaccines for Hepatitis B to the general population, with Hepatitis A vaccines available for children and specific groups.

Vaccination and Clinical Support
Beyond testing, the July campaigns focus on updating adult immunization records. In Juiz de Fora, individuals utilizing Pre-Exposure Prophylaxis (PrEP) for HIV will have the opportunity to update their vaccinations for Hepatitis A, Hepatitis B, and HPV, pending individual clinical assessment. For those diagnosed with the virus, the SUS provides free treatment. In Jundiaí, specialized care is managed through the Ambulatory of Infectious Diseases (AMI). While symptoms are often absent, potential indicators that warrant immediate medical attention include extreme fatigue, jaundice (yellowing of the eyes and skin), dark urine, and pale stools.
