Cyclospora – August 15, 2014

DSHS is investigating an outbreak of cyclosproiasis, an illness caused by the parasite Cyclospora that causes prolonged watery diarrhea and other gastrointestinal symptoms. DSHS has identified at least 164 cases this year, including a surge of reported cases beginning in mid-June.

Though a source has yet to be identified, past outbreaks have been traced to fresh imported produce. DSHS encourages people to wash produce thoroughly, though that may not entirely eliminate the risk because Cyclospora can be difficult to wash off.

Chikungunya – August 26, 2014

DSHS has confirmed 14 Texas cases of chikungunya, a virus that can cause fever and severe joint pain and is transmitted by mosquitoes. All cases have been imported, meaning that travelers have acquired the illness while visiting areas where the virus is more common. However, those imported cases mean there is a potential for chikungunya to spread in Texas because the Aedes mosquitoes that transmit it are present in the state.

Cases have been confirmed in Bexar, Brazoria, Collin, Dallas, Gonzales, Harris (3), Midland, Montgomery, Tarrant, Travis (2) and Williamson counties.

West Nile in Texas – August 26, 2014

DSHS has confirmed 41 cases of human West Nile illness in Texas this year.

West Nile is a mosquito-borne virus. There are two forms of the illness, West Nile neuroinvasive disease (WNND) and West Nile fever (WN fever). The symptoms of severe infection from West Nile neuroinvasive disease include headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis. West Nile fever is the milder form of the illness. Symptoms include fever, headache, body aches, and occasionally a skin rash on the trunk of the body and swollen lymph glands.

DSHS reminds Texans to reduce the risk of exposure by eliminating standing water and other mosquito breeding areas; making sure door, porch and window screens are in good condition; and using a repellent that contains DEET, picaridin, oil of lemon eucalyptus, IR3535 or para-menthane-diol products when outdoors.

Flu Surveillance – 2013-2014

The 2013-2014 flu season has ended, but DSHS will continue limited influenza surveillance throughout the summer. Weekly reports are available via the link below. Full flu surveillance will resume in the fall.

DSHS has confirmed 18 influenza-associated pediatric deaths in Texas for the 2013-2014 season. There is always some flu circulating, so people should continue to protect themselves and others even during the summer months by covering coughs and sneezes, washing hands frequently and staying home if sick.
