Published today. We found that hepatitis B was the leading cause of cirrhosis and HCC in southern Malawi. HCC is diagnosed at a very late stage. Huge opportunity to prevent liver-related death with community hepatitis B test and treat programmes. #hepsky #idsky

🧡 Dengue is no longer just a tropical disease - it's showing up in Europe.

This season, France, Italy, and Portugal (Madeira) have already reported locally acquired dengue cases.

Neurocysticercosis school outbreak in Belgium Human cysticercosis results from ingesting microscopic Taenia solium eggs shed by a tapeworm carrier, forming cystic larvae (ie, cysticerci) in tissues. These larvae normally encyst in the pig, the natural intermediate host. Upon consumption by humans, they develop into a new intestinal tapeworm. Affecting the human brain, neurocysticercosis is responsible for a third of epilepsy cases in endemic tropical and subtropical regions.1,2

Welcome to the wildest, most unexpected outbreak Belgium has seen. And no, this isn’t an episode of House MD but it reads like it.

Key public health message

What did you want to address in this study and why?

The parasite Toxoplasma gondii can cause severe disease in humans. People can acquire the parasite by eating raw or undercooked infected meat or unwashed fruits or vegetables contaminated with the parasite. We wanted to investigate T. gondii in commercial ready-to eat (RTE) salads in European countries to estimate the importance of these food products as sources of T. gondii.

What have we learnt from this study?

Using a molecular method, we detected T. gondii in 4.1% of 3,293 RTE salad samples from 10 European countries. Sampling in winter season, sampling and packaging of salad in Northern Europe and salad grown in Western Europe were associated with detection of T. gondii from salad samples.

What are the implications of your findings for public health?

As RTE salads are intended to be consumed raw without further processing, T. gondii in salad from European countries may lead to infections in humans. Measures to prevent and control contamination of salads are necessary. Further washing of RTE salads might be recommended for specific risk groups such as pregnant people.

πŸ₯— Washing your salad before you eat it is always a good idea, even if it is a "ready-to-eat" product
