CDC warns of rise in Cyclospora cases
The US Centers for Disease Control and Prevention (CDC) today warned health providers about an increase in the number of Cyclospora cases in the United States, with 206 infections in 27 states reported so far in people who were sick on or after May 1.
Most US Cyclospora cases are reported in the spring and summer, and earlier outbreaks have been tied to imported fresh produce, such as basil, cilantro, raspberries, and snow peas. However, the number of cases at this point in the year is higher than for the same time in 2016 when 88 infections had been reported.
In the middle of July, Texas reported increasing numbers of Cyclospora cases, and as of Aug 1, 160 illnesses had been reported in the state, most of them from Bexar and Harris counties. The CDC said most other states have relatively few cases. Eighteen patients have been hospitalized, and no deaths have been reported. So far no specific food source has been identified, and investigations are under way to determine the possible sources of infection.
Canada has also reported a Cyclospora outbreak, with 104 cases so far in Ontario and British Columbia.
Cyclosporiasis is an intestinal illness caused by ingesting food or water contaminated with the Cyclospora cayentanensis parasite. Symptoms include watery, profuse diarrhea along with fatigue, muscle pain, and low-grade fever. The infection is treated with trimethoprim/sulfamethoxazole; without treatment, the illness can last days to more than a month, with possible relapse.
The CDC urged health providers to consider cyclosporiasis in patients who have prolonged or relapsing diarrhea, to order specific Cyclospora testing if indicated, and to report cases to local health departments.

Another papaya brand recalled in Salmonella outbreak
The Food and Drug Administration (FDA) warned consumers to avoid both Caribena and Cavi brands of Maradol papayas, as well as any papayas packed and grown by Carica de Campeche in Mexico. The fruit are tied to an ongoing multistate Salmonella outbreak.
The move prompted New York distributor Agroson's LLC to stop importing papayas from Carica de Campeche. "As of today no illness has been reported from our Maradol Papaya Cavi Brand but we are doing a voluntary recall in cooperation with the FDA," the company said in an FDA press release.
Agroson said the papayas in question were distributed to wholesalers in New York, Connecticut, and New Jersey from Jul 16 to 19.
According to the FDA, papayas from the Carica de Campeche farm tested positive for Salmonella Kiambu, Salmonella Thompson, Salmonella Agona, Salmonella Senftenberg, and Salmonella Gaminara. So far, Salmonella Kiambu and Thompson have been implicated in 109 infections across the United States.
