Public health authorities are investigating a cluster of four Hepatitis A cases linked to a food establishment in Qormi. In a statement, health officials said the cases have been associated with Deli & Co, with investigations and contact tracing currently underway. Public health measures have also been put in place. Hepatitis A is a viral infection that affects the liver and is most commonly spread through contaminated food or water, or through close contact with an infected person. Health authorities are reminding the public that good hand hygiene, particularly after using the toilet and before handling food, remains one of the most effective ways to prevent transmission.
