[h=3]US shigellosis cases resistant to ciprofloxacin increase dramatically[/h] Shigellosis, until recently resistant to first-choice drug ciprofloxacin in only 2% of US cases, has been found resistant nearly 90% of the time in recent outbreaks, according to a study published online today in the Centers for Disease Control and Prevention's (CDC's) Morbidity Mortality Weekly Report (MMWR).
The authors evaluated 243 cases of shigellosis that occurred from May 24, 2014, to Feb 28, 2015, in 32 states and Puerto Rico. Of these, 95 occurred in a homeless population in San Francisco. About half of the remaining cases were linked with international travel. Resistance to ciprofloxacin was present in 109 (87%) of 126 isolates tested.
In an accompanying news release, the CDC recommends that physicians consider and discuss with patients whether illness is severe enough to warrant antibiotic treatment. When antibiotics are deemed necessary, providers should determine antibiotic susceptibility through laboratory testing.
Travelers should take extra precautions to prevent the disease through such actions as eating and drinking only safe foods and beverages (eg, cooked, boiled, bottled), washing hands frequently, and following meticulous hygiene regimens when ill, the agency added.
Shigella sonnei causes about 500,000 cases of diarrhea each year in the United States, many of them mild, the CDC said. Antibiotics are often used in the latter cases to shorten the illness even though it would likely resolve without treatment, say the study authors.

[h=3]Saudi Arabia reports its first April MERS case[/h] Saudi Arabia's Ministry of Health (MOH) today reported a MERS-CoV infection in a man in Jeddah, the first case this month.
The man with MERS-CoV (Middle East respiratory syndrome coronavirus) is a 51-year-old expatriate healthcare worker. He is listed in stable condition and had contact with a MERS patient.
The MOH also reported today that a 20-year-old male expatriate in Jeddah has recovered from the disease. He is not a health worker and had preexisting disease.
The new case brings the country's total to 974 MERS-CoV cases, including 422 deaths; in addition, 534 patients have recovered from their infections, and 18 patients remain hospitalized or in home isolation. The MOH confirmed 75 MERS cases in February and 53 in March.
