The Zika virus has gained significant attention due to its association with a surge of cases in Brazil, where there has been a notable increase in infants born with microcephaly and other serious brain abnormalities. Microcephaly is characterized by an abnormally small head size, indicating that the brain has not developed properly during pregnancy or after birth. This condition can also lead to various complications, including vision impairments, hearing loss, and growth deficiencies in affected infants.
Dr. Lisa Grant, a leading expert in the CDC’s birth defects division, mentioned in a recent interview that it remains uncertain how many babies born to the 279 affected women will experience brain defects due to Zika. The virus is primarily transmitted through bites from infected Aedes mosquitoes, but pregnant women can also acquire it through sexual contact with male partners who have traveled to areas where the virus is prevalent. Notably, there have been no documented cases of Zika transmission via mosquito bites within the continental U.S. thus far; individuals typically contract the virus during travel or through sexual intercourse.
Although Zika rarely results in fatalities, its symptoms—such as mild fever, rash, joint pain, and red eyes—are often so subtle that individuals may not seek medical attention. This poses challenges in accurately tracking the prevalence of the virus. It is essential to acknowledge that our understanding of Zika and its effects is still evolving, but there are preventative measures that can be taken. Travelers are advised to avoid regions currently experiencing Zika outbreaks, particularly in South America and Africa.
CDC Recommendations to Minimize the Risk of Zika Infection
To minimize the risk of Zika infection, the CDC recommends the following precautions:
- Utilize Environmental Protection Agency (EPA)-registered insect repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus, or para-menthane-diol. These products have been evaluated for safety and efficacy, even for those who are pregnant or breastfeeding.
- Adhere strictly to the instructions on product labels and reapply repellent as necessary.
- Avoid applying repellent on skin that is covered by clothing.
- If using sunscreen, apply it prior to the insect repellent.
- Wear long-sleeved shirts and long pants to reduce skin exposure.
- Seek accommodations with air conditioning and window/door screens to keep mosquitoes at bay.
- If outdoors in high-risk areas, consider sleeping under a mosquito bed net.
Additional Precautions for Infants
For the safety of infants, it is important to take additional precautions:
- Do not use insect repellent on babies under 2 months old.
- Avoid products containing oil of lemon eucalyptus or para-menthane-diol for children younger than 3 years old.
- Dress children in protective clothing that covers their arms and legs.
- Utilize mosquito netting over cribs, strollers, and baby carriers.
- Adults should apply repellent to their hands first before applying it to a child’s face.
