Article Synopsis
  • - The first confirmed case of SARS-CoV-2 in Tunisia was reported on March 3, 2020, leading to a rise in both imported and local cases, prompting a study on the virus's genetic diversity and epidemiology in the region.
  • - Researchers utilized whole genome sequencing on six highly positive SARS-CoV-2 samples from the early outbreak phase, uncovering distinct viral strains with a 0.1% nucleotide divergence rate clustered into six clades.
  • - The findings suggest that the virus was introduced multiple times in Tunisia and contribute valuable genomic data that could inform diagnosis and vaccine development globally.

Background: The epidemiological pattern of hepatitis A infection has shown dynamic changes in many parts of the world due to improved socio-economic conditions and the accumulation of seronegative subjects, which leads to possible outbreaks and increased morbidity rate. In Tunisia, the epidemiological status of hepatits A virus is currently unknown. However, over the past years higher numbers of symptomatic hepatitis A virus infection in school attendants and several outbreaks were reported to the Ministry of Health, especially from regions with the lowest socio-economic levels in the country.
