When schools welcome students back this fall, they should be proactive about preventing
Zika virus and know how to respond if cases arise, according to federal health officials.
The Centers for Disease Control and Prevention (CDC) has released new guidance detailing the steps K-12 schools should and should not take.
“We want schools to feel informed and prepared for Zika virus whether it’s a travel-associated
case in a child or staff member, or planning for the possibility of local transmission,”
said Eric Dziuban, M.D., D.T.M., FAAP, team lead for the CDC’s Children’s Preparedness
Zika virus is spread primarily through infected Aedes mosquitoes, although it also can be sexually transmitted. There have been more than
1,300 cases in U.S. states among travelers or sexual partners of travelers, but none
yet caused by local mosquitoes. However, CDC leaders say that could change this summer.
When the virus is spread from a pregnant woman to her fetus, it can cause microcephaly
and other brain abnormalities in the baby. However, children and adults who contract
it from mosquitoes typically have no symptoms or mild symptoms such as fever, rash,
joint pain and conjunctivitis.
The CDC made the following recommendations to schools:
Proactively communicate with public health authorities and families about preventing
Prevent mosquito transmission by getting rid of standing water on the property, mowing
the grass and using window screens or air conditioning if possible.
Instruct students and staff spending time outdoors to wear long pants and sleeves
when possible and use insect repellent. Consider risks associated with outdoor field
trips, and modify staff responsibilities if necessary to reduce their exposure to
Provide age-appropriate education on using condoms or abstinence to prevent sexual
transmission of Zika and on the risk of birth defects if the virus is passed from
a pregnant woman to her fetus.
Manage symptoms according to school illness policies. Do not remove or isolate Zika-infected
students or staff members or issue schoolwide notification. Privacy should be maintained.
If transmission is occurring in the community, it is not necessary to cancel classes
or outdoor activities. However, students or staff who are pregnant or trying to conceive
may request their time outdoors be limited.
The CDC drafted its interim guidance for schools with input from the Academy and other
experts. Dr. Dziuban said the advice could be applied across the country, even in
areas where Zika is unlikely to be transmitted locally because the Aedes mosquitoes do not live there.
“Many of these are good commonsense approaches that will help reduce mosquito bites
and any associated diseases,” he said.
Pediatricians also should familiarize themselves with the guidance.
“We know schools often engage with pediatricians and communicate closely with them
for health-related matters … so we feel pediatricians can play a role in understanding
this guidance, communicating with schools about it and providing help in cases where
a child’s health may be of concern,” Dr. Dziuban said.
