Yes, Zika virus can be sexually transmitted and is considered a sexually transmitted infection (STI) or sexually transmitted disease (STD).
While Zika virus is primarily known for its transmission through the bite of infected Aedes species mosquitoes, sexual transmission is a significant route of spread. An individual infected with the Zika virus can transmit it to their sex partners, even if they are asymptomatic and show no signs of illness.
The virus has been found to persist in bodily fluids, notably persisting longer in semen than in other fluids, which contributes to its potential for sexual transmission. This means that an infected person might be able to spread the virus sexually for an extended period after their initial exposure or symptoms have resolved.
Preventing Sexual Transmission of Zika
To protect sex partners from Zika virus infection, especially those concerned about exposure or who have traveled to areas with active Zika transmission, the following measures are recommended:
- Using condoms consistently and correctly during any sexual activity (vaginal, anal, or oral).
- Abstinence from sexual activity.
Understanding all routes of transmission, including sexual transmission, is crucial for preventing the spread of Zika virus and for public health efforts. For more comprehensive information on Zika virus, including symptoms, prevention, and travel advisories, you can visit the Centers for Disease Control and Prevention (CDC) website.
