A Salmonella outbreak in Latvia has sickened at least 120 people.
The Center for Disease Prevention and Control (SPKC) initially received information about 40 cases of acute intestinal infection in two preschools in Riga.
An epidemiological investigation was started to find the source, and laboratory examination of stool samples was organized.
The number of registered cases has now reached 120. Efforts are continuing to ensure that stool samples from ill people and their contacts are sent for lab analysis.
Authorities in Riga have asked for an explanation from the catering provider to help identify possible causes of sickness. Safety measures include increased disinfection of the two premises.
Patients include children and adult employees. Recommendations and information have been sent to the relevant authorities and parents of children, as well as the Latvian Food and Veterinary Service (PVD).
Symptoms are mostly characterized as moderate, with fever and diarrhea but local media reported a few children have needed hospital treatment.
Initial results of laboratory examinations show that in most cases Salmonella has been identified as the causative agent. However, other agents have also been detected, including norovirus, rotavirus and yersiniosis.
In all of 2024, Latvia reported 211 salmonellosis cases compared to 101 in 2023.
About Salmonella
Food contaminated with Salmonella bacteria does not usually look, smell, or taste spoiled. Anyone can become sick with a Salmonella infection. Infants, children, seniors, and people with weakened immune systems are at higher risk of serious illness because their immune systems are fragile.
Anyone who has developed symptoms of Salmonella infection should seek medical attention. Sick people should tell their doctors about the possible exposure to Salmonella bacteria because special tests are necessary to diagnose salmonellosis. Salmonella infection symptoms can mimic other illnesses, frequently leading to misdiagnosis.
Symptoms of Salmonella infection can include diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating contaminated food. Otherwise healthy adults are usually sick for four to seven days. In some cases, however, diarrhea may be so severe that patients require hospitalization.
Older adults, children, pregnant women, and people with weakened immune systems, such as cancer patients, are more likely to develop a severe illness and serious, sometimes life-threatening conditions. Some people are infected with Salmonella without getting sick or showing any symptoms. However, they may still spread the infections to others.
