The updates, health officials said, come "after careful consideration of all available scientific evidence, consultation with other public health agencies, and taking into consideration the potential serious health consequences of Zika virus infection to pregnant women and children born to women exposed to Zika virus during pregnancy".
The greatest concern is for unborn babies when the mother is infected with the Zika virus, which can cause small head syndrome, brain damage and other birth defects. In March, the U.S. Food and Drug Administration approved an experimental test to check blood donations for the Zika virus.
The department had confirmed eight cases at the beginning of the month.
Developed symptoms suggestive of Zika virus infection during the past four weeks.
In Maryland, there have been 77 travel related cases, according to the state Department of State and Mental Hygiene.
Zika is typically spread through the bite of the Aedes aegypti mosquito, but evidence has been accumulating that it can also be transmitted through sexual contact and blood transfusions, officials have said.
Blood testing began last month in parts of Florida after the first cases of homegrown Zika occurred in Miami.
"The finding may be important for women, not only pregnant women", said Iwasaki.
Dr Chan Fuk-woo, a clinical assistant professor at the Department of Microbiology of the University of Hong Kong, said the symptoms shown by the patient are typical of Zika virus infection, which is sometimes hard to detect.
This new twist in the myriad ways Zika can spread should strengthen warnings to couples hoping to start a family if either one plans to travel anywhere the virus is active, health officials said.
"The Zika virus appears to have a niche within the vagina", study senior author Akiko Iwasaki, an immunobiologist at Yale University, said in a journal news release. No such cases have been reported in the United States.
Partners of pregnant women are advised to use a condom to guard against sexual transmission during pregnancy.
Brazil is the country hit hardest by Zika, with thousands of cases of microcephaly reported so far.
The American Red Cross has also asked potential blood donors who have traveled to Zika-affected areas to wait 28 days before giving blood. Those infected by Zika rarely need to go to the hospital and very few die from the virus, according to the Atlanta-based Centers for Disease Control and Prevention.
