Background: Chad with 7,698 confirmed cases of infection and 194 deaths since the beginning of the COVID-19 pandemic, is one of the African countries with the lowest reported case numbers. However, this figure likely underestimates the true spread of the virus due to the low rate of diagnosis. The high rate of asymptomatic infections reflects the reality of SARS-CoV-2 transmission in Chad.

After several reported outbreaks, the current extent of infections caused by this orthoflavivirus in the Sahel remains to be explored. We investigated the prevalence of neutralizing antibodies against ZIKV in the general population, in HIV-infected individuals and in livestock in Chad using a seroneutralization assay that ensures high specificity level.

- Q fever (QF) and Rift Valley fever (RVF) are prevalent zoonotic diseases in Africa that pose health and economic challenges, and accurate prevalence estimates are essential for effective disease control.
- The study assessed the agreement of diagnostic test results for QF and RVF in both humans and livestock across various labs and test types, using samples collected from rural Chad.
- Findings indicated fair to moderate inter-laboratory agreement in test results, highlighting that demographic factors such as age and location significantly influence test outcomes, emphasizing the importance of considering these variables in future epidemiological research.
Introduction: Tuberculosis (TB) is an infectious zoonotic disease caused by bacteria belonging to the complex. In sub-Saharan African countries such as Chad, TB is endemic and causes a high burden on humans and animals through morbidity, mortality, and reduced productivity in livestock. To effectively prevent and control the disease, strong coordination between policymakers, health and veterinary services, civil society organizations, and communities is needed.

This case-control study aimed to evaluate serum levels of various immunological markers in patients with COVID-19 compared to those with bacterial pneumonia and a healthy control group. Serum samples were collected from adult participants across various COVID-19 isolation centers, including Kassala State and Ahmed Gasim Hospital, between April and June 2021.
