Shigellosis – Sweden
Sweden reports 30 cases of shigella infection with a travel connection to Cape Verde since mid-November.
Eleven bacterial isolates have so far been determined to species: nine Shigella sonnei and two Shigella boydii. The spread of infection in Cape Verde has also been noticed by several other European countries.
Among Swedish travelers, infections with other intestinal pathogens, for example EHEC, Campylobacter, Cryptosporidium and Giardia, have also been noted. Infection with Shigella in connection with trips to Cape Verde has been a recurring problem. This and the presence of various Shigella species and other intestinal pathogens suggest contamination via food.

Shigellosis is an infection of the intestines caused by Shigella bacteria. Symptoms generally start one to two days after exposure and include diarrhea, fever, abdominal pain, and feeling the need to pass stools even when the bowels are empty. he diarrhea may be bloody. Symptoms typically last five to seven days and it may take several months to fully recover. There is no vaccine and Shigellosis usually resolves without specific treatment.
Globally shigellosis occurs in at least 80 million people and results in about 700,000 deaths a year. Most cases occur in the developing world. Young children are most commonly affected.
