Zika Virus Infections in Maryland

In recent months, Zika virus has spread from Brazil to the southern U.S. and northward. It generally causes mild symptoms, including rashes and aches, and those who are infected may not even feel ill enough to visit a doctor. However, the virus can cause birth defects when a pregnant woman contracts it.

Zika in Maryland

As of June 3, there have been 17 reported cases of Maryland residents infected with the Zika virus. All of them contracted the virus while traveling outside the country, but Zika can be transmitted both by mosquitoes and through sexual contact.

Symptoms and Birth Defects

Most of the Zika virus’s symptoms are fairly non-serious. They may include rash, fever, joint pain, aches, fatigue, headache, and conjunctivitis, and can last from several days to a week.

But the CDC has confirmed that Zika can cause birth defects in fetuses when a pregnant woman becomes infected. One of the most serious potential birth defects is microcephaly, where an infant is born with an unusually small head. Zika can also cause severe fetal brain defects. Other potential birth defects include eye defects, impaired growth, and hearing loss. Not all babies born to infected mothers will have birth defects, but microcephaly and brain defects are very serious, so it is wise to take preventive measures.


Zika virus is transmitted through the bite of an infected Aedes species of mosquitoes. This species of mosquito breeds in pools of standing water and can breed in as little water as fits in a bottle cap. Aedes mosquitoes bite during the day and are the same mosquitoes that spread dengue and chikungunya viruses.

Uniquely, the Zika virus can also be sexually transmitted. The live virus has been found in semen up to two months after symptoms have abated and after the period during which it is detectible in the blood.

There have also been reports of transmission through blood transfusions in Brazil, but none in the U.S.


Zika can be prevented by avoiding mosquito bites. Preventive measures include:

  • Using insect repellent;
  • Staying indoors as much as possible and wearing long sleeves and pants while outdoors in Zika endemic areas;
  • Sleeping under mosquito netting; and
  • Treating clothing and gear with permethrin.

Pregnant women especially should avoid travel to Zika endemic areas in South and Central America and the Caribbean, and women who have traveled to these areas may want to delay pregnancy. Since Zika can be spread sexually by an infected man, it is essential to always use condoms.

The rate of Zika virus infection is low in the U.S., and preventive measures are possible. But potential consequences for pregnant women and their babies are extremely serious. If you have become infected with Zika, and your doctor has failed to diagnose or properly treat the virus, you may have a medical malpractice claim for any resultant birth defects.
