Frequently,
only supportive care required.
Replenishment of fluids and electrolytes with juices, water, and caffeine-free
soda will help prevent dehydration from the diarrhea. However, for more
severe cases, the only known treatment of Cyclospora infection is
Trimethoprim/sulfamethoxazole (TMP/SMX).
Typically, adults receive TMP orally twice a day for 7 days. Children
receive TMP twice a day for 7 days. Patients with AIDS may need higher doses
and long-term maintenance treatment. |

There is a plethora of information about the structure and chemical properties of various medicines including Trimethoprim on the web. For the chemically inclined, they even have IR spectroscopy! |

Epidemiology |
|||
|
|
By and large, the epidemiology of Cyclosporiasis has yet to
be determined. Cyclosporiasis has
been reported in many countries, but it is endemic only in tropical and
subtropical areas (Haiti, Nepal, and Peru). The prevalence is strongly
associated with the seasons, and predominates during the rainy spring or summer
months. Cases also have been reported in travelers returning from Mexico,
Southeast. |
||
|
Asia, Puerto Rico, Indonesia,
Morocco, Pakistan, and India.
Since1990, there have been many outbreaks of cyclosporiasis in the
United States and Canada which affected approximately 3600 persons. Many
cases involved Guatemalan raspberries, or the consumption of food that
contained fresh basil. An additional two clusters of cases in Florida were
linked with eating mesclun lettuce.
It should be noted that the chances for foodborne
transmission are greatly reduced by washing fruits and vegetables before
consumption. Ultimately, the
prevalence of Cyclospora in North America is estimated at levels lower
than .5%. |

Public Health and Prevention Currently, there is no vaccine available for Cyclospora infection. However, given the lack of other hosts and a reservoir, many cases of Cyclospora in endemic areas could be prevented with proper hygiene, treatment, sanitation and filtration of water. Additionally, simply washing and rinsing fruits before serving has been shown to significantly decrease the amount of oocysts on the fruit. Also, all cases should be reported to the CDC so that the incidence of Cyclospora infection can be properly monitored. |
