Announcing a new article publication for Zoonoses journal. The objectives of this study were to characterise the epidemiology of human and animal brucellosis in the eastern Algerian province of Constantine, and to identify the interactions between humans and animals, to establish strategies from a unique health perspective considering the context of endemicity and eradication challenges.
Data collected from official institutions regarding brucellosis in humans and animals in Constantine and seven other provinces from 2015 to 2023 (until August 2022 for animals) were analysed to estimate temporal trends, alert thresholds, and correlations between humans and animals.
A total of 163 brucellosis cases in humans were recorded in Constantine between 2015 and 2023, and the annual average was 1.47/100,000. The epidemic threshold was exceeded in 2021 and 2022. Males and residents 20–44 years of age were the most affected groups. In cattle, the prevalence was 1.32%, and the screening rate was below 7.5%. The only significant correlation was observed between humans and goats (r = −0.747, p = 0.03). The southern Constantine region was the most affected.
Brucellosis is an underestimated public health threat in Algeria. Gaps in its management include inadequate screening of goats, insufficient vaccination coverage and underreporting. The implementation of more comprehensive surveillance programmes is imperative.

For well over a decade, in my capacity as a researcher, broadcaster, and producer, I have relied heavily on Alphagalileo.
All of my work trips have been planned around stories that I've found on this site.
The under embargo section allows us to plan ahead and the news releases enable us to find key experts.
Going through the tailored daily updates is the best way to start the day. It's such a critical service for me and many of my colleagues.
Koula Bouloukos, Senior manager, Editorial & Production Underknown
We have used AlphaGalileo since its foundation but frankly we need it more than ever now to ensure our research news is heard across Europe, Asia and North America. As one of the UK’s leading research universities we want to continue to work with other outstanding researchers in Europe. AlphaGalileo helps us to continue to bring our research story to them and the rest of the world.
Peter Dunn, Director of Press and Media Relations at the University of Warwick
AlphaGalileo has helped us more than double our reach at SciDev.Net. The service has enabled our journalists around the world to reach the mainstream media with articles about the impact of science on people in low- and middle-income countries, leading to big increases in the number of SciDev.Net articles that have been republished.
