Shepherd Independent School District is reporting a chickenpox outbreak at Shepherd High School, with three confirmed cases and four suspected cases among the school's 573 students. The district sent a note to parents on Tuesday alerting them to the outbreak and said it is monitoring the situation closely.

According to FOX 26 Houston, the district said an outbreak of chickenpox, or varicella, has been reported at the high school and that officials are “monitoring the situation and taking appropriate precautions to help prevent further spread.” The seven combined confirmed and suspected cases represent about 1.2% of the student body, according to figures reported by ABC13, which cited the district superintendent.

Homecoming Dance Possibly Linked to Spread

The outbreak may have stemmed from the school's homecoming dance on Oct. 3, the same outlet reported, though the exact source of transmission has not been confirmed. The district's earlier announcement on Oct. 8 said a student who attended that school-sponsored event was later reported to have chickenpox, per the same account.

The district said the State Department of Health Services has officially confirmed the outbreak, the station's report noted. Shepherd ISD provided the information used in FOX 26's reporting on the situation.

What Symptoms to Watch For

District officials have advised parents to watch their children for possible symptoms over the next 10 to 21 days, including fever, tiredness, headache, and an itchy rash or blisters, per the same account from ABC13. Fox 26 Houston reported that chickenpox commonly causes fever, tiredness, headache, and loss of appetite, and that those symptoms may begin one to two days before the rash itself appears.

The rash often starts on the face, scalp, or trunk before spreading to other parts of the body, developing into an itchy, fluid-filled set of blisters that eventually scab over, the outlet reported. Health officials note that children who have already been vaccinated can still develop chickenpox, though their symptoms tend to be milder.

Broader Context on Varicella Outbreaks

Collin County Health Care Services has also issued a health alert due to an increase in chickenpox cases, according to Cook Children's. Federal guidance from the CDC notes that varicella outbreaks in settings like schools can last months, particularly where vaccination coverage is low, and that vaccination should still be offered even when an outbreak is identified late.

Texas health guidance outlined by the Texas Department of State Health Services calls for children to receive two doses of the varicella vaccine, the first between 12 and 15 months of age and the second between ages 4 and 6. For now, Shepherd ISD says it continues monitoring the outbreak and taking precautions intended to protect students and staff as the district awaits word on whether additional cases emerge.
