CDC, AAP release algorithms on testing infants for Zika virus

The Centers for Disease Control and Prevention (CDC), in collaboration with the Academy,
released algorithms Tuesday on caring for infants whose mothers may have been infected
with Zika virus.
“This is critical step-by-step guidance for pediatricians in the care of infants and
families where there’s a question of exposure to the Zika virus,” said Fan Tait, M.D.,
FAAP, AAP associate executive director and director of the Department of Child Health
Dr. Tait, AAP staff and leadership of the AAP Committee on Infectious Diseases, Disaster
Preparedness Advisory Council, Committee on Fetus and Newborn, Council on Children
with Disabilities, Section on Neurology and Section on Neonatal-Perinatal Medicine
collaborated with the CDC in the development and review of the algorithms.
The interim guidelines published in a Morbidity and Mortality Weekly Report come as officials continue to study a possible link between Zika virus in pregnant
women and microcephaly in their babies. Officials are urging pediatric health care providers to work with
obstetricians to identify women who may have been infected while spending time in an affected country during their pregnancy.
Their infants should be tested for Zika if they are born with microcephaly or intracranial
calcifications. They also should be tested if these conditions are not detected prenatally
or at birth but their mother had a positive or inconclusive test for Zika. Pediatricians
should contact their state health department to facilitate these tests.
The guidelines also recommend numerous clinical evaluations for infants with possible
Zika infection or microcephaly.
The CDC has issued a travel advisory urging women who are pregnant to avoid traveling to areas in Latin America and the
Caribbean where the virus is spread by mosquitoes. On Tuesday, it added the U.S. Virgin
Islands and Dominican Republic to that list, bringing the total number of countries
and territories to 24. If women who are pregnant or trying to become pregnant do travel,
they should take steps to avoid mosquito bites. There are no vaccines to protect against Zika virus.
“As the implications of exposure to Zika virus become a greater threat to the health
of newborns and mothers, pediatricians have an increasing role in the identification
and testing of infants that have been exposed,” said AAP President Benard P. Dreyer,
M.D., FAAP, who encouraged members to refer to this new algorithm.
Zika is a Flavivirus like West Nile and dengue and can be tough to diagnose. Roughly
one in five people will develop symptoms that may include fever, rash, joint pain
and conjunctivitis. Some people also may experience headache, muscle pain or vomiting.
