A drug-resistant stomach disease, known as shigellosis, has witnessed an uptick in the number of cases reported last year, according to the US Centers for Disease Control and Prevention (CDC).
A CDC study, which was released on Thursday, showed 243 people were tested positive for multi-drug resistant shigella sonnei bacteria across 32 states and Puerto Rico from May 2014 to February 2015.
The experts said all the reported cases of last year were resistant to the antibiotic ciprofloxacin, a traditional medication for the stomach infection which is often prescribed to the people in the US who are traveling abroad and develop diarrhea.
Not only ciprofloxacin, Shigellosis has been proven resistant to several other antibiotics, such as trimethoprim/sulfamethoxazole and ampicillin.
Calling the treatment of drug-resistant infections tougher, CDC Director Tom Frieden said, “These outbreaks show a troubling trend in shigella infections in the US. As Shigella spreads so easily between people, the potential for more and even larger outbreaks is a real concern.”
“We’re moving quickly to implement a national strategy to curb antibiotic resistance because we can’t take for granted that we’ll always have the drugs we need to fight common infections,” Frieden said.
Clusters of the ailment were uncovered in California, Massachusetts and Pennsylvania. 90 percent of the cases were resistant to ciprofloxacin.
Nearly half of the cases identified by the CDC’s PulseNet labs were detected among people who had traveled to India and the Dominican Republic. A large uptick in cases was reported in San Francisco, especially among those people who were homeless or living in hotels with single-room occupancy.
The US reports an estimated 500,000 cases of shigellosis each year.
Some of the common symptoms of shigellosis include bloody or watery diarrhea, fever, abdominal pain and malaise.
