Suspected Female-to-Male Sexual Transmission of Zika Virus - New York City, 2016 Weekly / July 15, 2016
 
http://www.cdc.gov/mmwr/volumes/65/wr/mm6528e2.htm
 
A routine investigation by the New York City (NYC) Department of Health and Mental Hygiene (DOHMH) identified a nonpregnant woman in her twenties who reported she had engaged in a single event of condomless vaginal intercourse with a male partner the day she returned to NYC (day 0) from travel to an area with ongoing Zika virus transmission. She had headache and abdominal cramping while in the airport awaiting return to NYC. The following day (day 1) she developed fever, fatigue, a maculopapular rash, myalgia, arthralgia, back pain, swelling of the extremities, and numbness and tingling in her hands and feet. In addition, on day 1, the woman began menses that she described as heavier than usual. On day 3 she visited her primary care provider who obtained blood and urine specimens. Zika virus RNA was detected in both serum and urine by real-time reverse transcription-polymerase chain reaction (rRT-PCR) performed at the DOHMH Public Health Laboratory using a test based on an assay developed at CDC (1). The results of serum testing for anti-Zika virus immunoglobulin M (IgM) antibody performed by the New York State Department of Health Wadsworth Center laboratory was negative using the CDC Zika IgM antibody capture enzyme-linked immunosorbent assay (Zika MAC-ELISA) (2).
 
Seven days after sexual intercourse (day 6), the woman's male partner, also in his twenties, developed fever, a maculopapular rash, joint pain, and conjunctivitis. On day 9, three days after the onset of his symptoms, the man sought care from the same primary care provider who had diagnosed Zika virus infection in his female partner. The provider suspected sexual transmission of Zika virus and contacted DOHMH to seek testing for the male partner. That same day, day 9, urine and serum specimens were collected from the man. Zika virus RNA was detected in urine but not serum by rRT-PCR testing at the DOHMH Public Health Laboratory. Zika virus IgM antibodies were not detectable by the CDC Zika MAC-ELISA assay performed at the New York State Department of Health Wadsworth Center. The CDC Arbovirus Disease Branch confirmed all rRT-PCR results for urine and serum specimens from both partners.
 
During an interview with DOHMH on day 17, the man confirmed that he had not traveled outside the United States during the year before his illness. He also confirmed a single encounter of condomless vaginal intercourse with his female partner (the patient) after her return to NYC and reported that he did not engage in oral or anal intercourse with her. The man reported that he noticed no blood on his uncircumcised penis immediately after intercourse that could have been associated either with vaginal bleeding or with any open lesions on his genitals. He also reported that he did not have any other recent sexual partners or receive a mosquito bite within the week preceding his illness. Independent follow-up interviews with the woman and man corroborated the exposure and illness history. The patients were consistent in describing illness onset, symptoms, sexual history, and the woman's travel. This information also was consistent with the initial report from the primary care provider.
 
The timing and sequence of events support female-to-male Zika virus transmission through condomless vaginal intercourse. The woman likely was viremic at the time of sexual intercourse because her serum, collected 3 days later, had evidence of Zika virus RNA by rRT-PCR. Virus present in either vaginal fluids or menstrual blood might have been transmitted during exposure to her male partner's urethral mucosa or undetected abrasions on his penis. Recent reports document detection of Zika virus in the female genital tract, including vaginal fluid. A study on nonhuman primates found Zika virus RNA detected in the vaginal fluid of three nonpregnant females up to 7 days after subcutaneous inoculation (3), and Zika virus RNA was detected in specimens from a woman's cervical mucous, genital swab, and endocervical swab collected 3 days after illness onset, using an unspecified RT-PCR test (4). Further studies are needed to determine the characteristics of Zika virus shedding in the genital tract and vaginal fluid of humans.
 
This case represents the first reported occurrence of female-to-male sexual transmission of Zika virus. Current guidance to prevent sexual transmission of Zika virus is based on the assumption that transmission occurs from a male partner to a receptive partner (5,6). Ongoing surveillance is needed to determine the risk for transmission of Zika virus infection from a female to her sexual partners. Providers should report to their local or state health department any patients with illnesses compatible with Zika virus disease who do not have a history of travel to an area with ongoing Zika virus transmission, but who had a sexual exposure to a partner who did travel.
 
Persons who want to reduce the risk for sexual transmission of Zika virus should abstain from sex or correctly and consistently use condoms for vaginal, anal, and oral sex, as recommended in the current CDC guidance (5). Guidance on prevention of sexual transmission of Zika virus, including other methods of barrier protection, will be updated as additional information becomes available (http://www.cdc.gov/zika).

Woman found to spread Zika virus through sex for first time
 
NEW YORK -- A New York City woman has infected her male partner with Zika virus through sex, the first time female-to-male transmission of the illness has been documented. Zika is usually spread by mosquitoes, and health officials have known for some time that men can spread it through sex.
 
In most people, the Zika virus causes only a mild illness, and often there are no symptoms at all. But infection during pregnancy can lead to severe brain-related birth defects in the baby.
 
The New York woman was not pregnant.
 
The CDC said the woman and her partner had unprotected intercourse the day she returned from travel to a country where Zika is spreading. The disease is widespread in many countries in Latin America and the Caribbean. The following day, the woman developed fever, fatigue, a rash, muscle and joint pain, and other symptoms and went to the doctor. Blood and urine tests confirmed she was infected with Zika.
 
The CDC reports her partner, who had not traveled to the region, developed symptoms about a week later and also tested positive for Zika.
 
The new finding prompted the Centers for Disease Control and Prevention to update its advice in a report issued Friday. The CDC now advises pregnant women to use protection if their sex partner has traveled to a Zika-infected region, whether the partner is a man or a woman.

Mosquitoes suspected in more Florida Zika cases

Florida counties ordered to stop blood collections amid Zika fears....http://www.cbsnews.com/news/zika-us-cases-pause-blood-bank-collections-two-south-florida-counties/
 
Florida Gov. Rick Scott will hold a press conference in Orlando Friday to discuss the ongoing Zika investigation in South Florida. There's currently no vaccine for the virus, but this week, a pharmaceutical company administered its first dose of an experimental Zika vaccine to a volunteer.
 
Parts of South Florida are being asked to stop collecting blood because of the latest Zika fears. The FDA warning Thursday affects blood banks in two counties. Beginning Friday, one of Florida's largest blood banks - OneBlood -- will start testing every blood donation it receives for Zika.
 
The FDA asked blood centers in Miami-Dade and neighboring Broward counties Thursday to immediately stop collecting donations, until each unit of blood can be screened for the virus, reports CBS News correspondent David Begnaud. The precaution follows four cases of Zika that may not have been transmitted by mosquitoes abroad - possibly the first mosquito-borne transmissions in the continental U.S.

Basics of Zika Virus and Sex.....http://www.cdc.gov/zika/transmission/sexual-transmission.html
 
Transmission
 
⋅ Zika can be passed through sex from a person who has Zika to sex partners.
⋅ Sex includes vaginal, anal, oral sex, and the sharing of sex toys.
⋅ Studies are underway to find out how long Zika stays in the semen and vaginal fluids
 
of people who have Zika, and how long it can be passed to sex partners. We know that Zika can remain in semen longer than in other body fluids, including vaginal fluids, urine, and blood.
 
Prevention Basics
⋅ Condoms and other barriers* can reduce the chance of getting Zika from sex.

Tallahassee, Fla.-In an effort to keep Florida residents and visitors safe and aware about the status of the Zika virus, the Florida Department of Health will issue a Zika virus update each week day at 2 p.m. Updates will include a CDC-confirmed Zika case count by county and information to better keep Floridians prepared.
 
There are 17 new travel-related cases today with three in Palm Beach, two in Brevard, two in Broward, two in Orange, one in Escambia, one in Osceola, one in Polk, one in Seminole and four involving a pregnant women. According to CDC, symptoms associated with the Zika virus last between seven to 10 days.
 
The department is expanding its ongoing investigations with two additional possible non-travel related Zika virus cases in Miami-Dade and Broward counties. This pattern is consistent with other mosquito-borne virus investigations, such as the 2013 dengue response.
 
The investigations into the new cases will begin today and door-to-door outreach and sample collection are ongoing in all cases. The department will share more details as they become available. Residents and visitors are urged to participate in requests for urine samples by the department in the areas of investigation. These results will help the department determine the number of people affected.
 
Zika prevention kits and repellent are being distributed in the areas of investigation, through local OBGYN offices and at both DOH-Broward and DOH-Miami-Dade.
 
Residents and visitors with questions regarding Zika are reminded to call the Zika Virus Information Hotline at 1-855-622-6735.
 
CDC recommends that women who are pregnant or thinking of becoming pregnant postpone travel to Zika affected areas. According to CDC guidance, providers should consider testing all pregnant women with a history of travel to a Zika affected area for the virus. CDC recommends that a pregnant woman with a history of Zika virus and her provider should consider additional ultrasounds.
 
Florida has been monitoring pregnant women with evidence of Zika regardless of symptoms since January. The total number of pregnant women who have been monitored is 53, with 17 having met the previous CDC case definition.
 
The Council of State and Territorial Epidemiologists and CDC released a new case definition for Zika that now includes reporting both asymptomatic and symptomatic cases of Zika. Prior to this change, states reported only symptomatic non-pregnant cases and pregnant cases regardless of symptoms. This change comes as a result of increased availability for testing in commercial laboratories.
