End of Summer Travelers Urged to Take Precautions to Prevent Zika
SACRAMENTO – Travelers coming back from the Olympic Games in Rio and other vacation spots where the Zika virus is spreading are urged to take precautions upon return to help prevent the spread of the virus in California. While the virus is primarily transmitted by Aedes mosquitoes, it can also pass from one person to another during sex.
"Summer travelers who spent time in Brazil or any other region with Zika-infected mosquitoes can protect themselves, their families and community members by taking a few simple steps,” said California Department of Public Health Director and State Health Officer Dr. Karen Smith. “Continue using insect repellent to prevent spreading the virus to mosquitoes in your community upon your return and refrain from unprotected sex so you don’t pass the virus to your partner."
Men and women should use condoms for at least eight weeks after travel, and men who have tested positive for Zika should use condoms for six months to prevent transmission to their partners. Travelers returning from an affected region should also continue using insect repellent for three weeks to prevent the virus from spreading to mosquitoes, which might then infect others.
"Pregnant women and couples planning to have children need to be especially cautious because Zika can cause significant harm to a developing fetus," said Dr. Smith. "Pregnant women who have traveled to an area with Zika should inform their doctor upon return, and couples returning from an affected area should speak with a doctor before getting pregnant."
Zika virus infection during pregnancy can cause severe birth defects, including microcephaly. Two infants with Zika-related microcephaly have been born in California this year to women who had Zika virus infections during pregnancy after spending time in an area where the virus is circulating in mosquitoes.
While mosquitoes that can carry the virus have been found in 12 California counties, there is no evidence these mosquitoes are transmitting Zika in the state at this time. A team of experts across several disciplines at CDPH is working closely with local public health departments, vector control agencies and the medical community to ensure that California is responding aggressively and appropriately to the emerging threat of Zika virus.
As of August 19, CDPH has confirmed 170 travel-associated Zika virus infections in 26 counties. A total of 24 infections have been confirmed in pregnant women.

NEWS RELEASE - August 4, 2016
CDPH Reports Two Cases of Zika-Related Birth Defects in California
SACRAMENTO – The California Department of Public Health (CDPH) reported today that two infants with Zika-related microcephaly have been born in California to women who had Zika virus infections during pregnancy after spending time in a country where the virus is endemic. While mosquitoes that can carry the virus have been found in 12 California counties, there is no evidence these mosquitoes are transmitting Zika in the state at this time.
"This is a sobering reminder for Californians that Zika can cause serious harm to a developing fetus," said CDPH Director and State Health Officer Dr. Karen Smith. "We join the Centers for Disease Control and Prevention (CDC) in urging pregnant women to avoid travel to areas with known Zika transmission. Pregnant women who must travel to one of these areas should strictly follow steps to prevent mosquito bites and speak with a health care provider upon return."
"Zika virus can also be transmitted to sexual partners by both males and females. Both men and women of childbearing age should take precautions if they have recently traveled, or plan to travel, to a location where Zika is spreading," added Dr. Smith.
A team of experts across several disciplines at CDPH is working closely with local public health departments, vector control agencies and the medical community to ensure that California is responding aggressively and appropriately to the emerging threat of Zika virus. CDPH is actively monitoring all pregnant women with Zika infection in California. The Department is also collaborating with local health departments to provide assistance to families with infants born with Zika-related birth defects to ensure they receive appropriate medical care. Infants born to mothers with confirmed infections will be monitored for one year.
As of July 29, CDPH has confirmed 114 travel-associated Zika virus infections in 22 counties. A total of 21 infections have been confirmed in pregnant women. This information is updated every Friday on the CDPH Zika website.
While Zika infection is often asymptomatic, those who do have symptoms report fever, rash, joint pain and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting for several days to a week after being bitten by an infected mosquito. There is currently no vaccine or treatment for Zika other than supportive care, rest, fluids and fever relief. People traveling to areas with known Zika transmission should take steps to avoid mosquito bites:
Sexually active adults who travel to areas with Zika transmission should use condoms or other barriers in order to avoid getting or passing Zika during sex. Couples planning pregnancy should speak with a health care provider about a safe time to wait before trying to get pregnant.
CDPH provides Zika-related pregnancy outcome data to the U.S. Zika Pregnancy Registry maintained by the CDC. The CDC is collecting this information to better understand the risks posed by Zika infection during pregnancy.
In order to protect privacy, CDPH is not releasing additional details or the locations of the mothers and children. Infants born with birth defects, including microcephaly, as a result of maternal Zika infection do not pose a public health risk to their communities.

CDC encourages following guidance to prevent sexual transmission of Zika virus
CDC has committed to sharing the latest information on Zika virus as it becomes available. On February 5, 2016, CDC published interim recommendations for protecting people against sexual transmission of Zika virus. This guidance was issued after lab confirmation of the first case of Zika virus infection in a non-traveler in the continental United States, which was linked to sexual contact with an infected partner.
CDC and state public health departments are now investigating 14 new reports of possible sexual transmission of Zika virus, including several involving pregnant women. In two of the new suspected sexual transmission events, Zika virus infection has been confirmed in women whose only known risk factor was sexual contact with an ill male partner who had recently traveled to an area with local Zika virus transmission; testing for the male partners is still pending. For four additional suspected sexual transmission events, preliminary laboratory evidence (IgM antibody test) is available for the women, but confirmatory tests are pending. For eight other suspected events, the investigation is ongoing. In all events for which information is available, travelers were men and reported symptom onset was within 2 weeks before the non-traveling female partner's symptoms began. Like previously reported cases of sexual transmission, these cases involve possible transmission of the virus from men to their sex partners. At this time, there is no evidence that women can transmit Zika virus to their sex partners; however, more research is needed to understand this issue.
Although sexual transmission of Zika virus infection is possible, mosquito bites remain the primary way that Zika virus is transmitted. Because there currently is no vaccine or treatment for Zika virus, the best way to avoid Zika virus infection is to prevent mosquito bites.
Because these new reports suggest sexual transmission may be a more likely means of transmission for Zika virus than previously considered, CDC issued a Health Advisory Notice (HAN) today to underscore the importance of adhering to the interim guidance published on February 5.
The CDC's February 5 interim guidance includes:
Recommendations for pregnant women and men with pregnant sex partners who live in or have traveled to Zika-affected areas:
Recommendations for non-pregnant women, and men with non-pregnant sex partners who live in or have traveled to Zika-affected areas:
These investigations are preliminary, and CDC will continue to update its guidance as more information becomes available.

California Department of Public Health Reminds Public to Guard Against Mosquito Bites
SACRAMENTO - California Department of Public Health (CDPH) Director and State Public Health Officer Dr. Karen Smith today advised that although there is no evidence of mosquitoes carrying Zika virus in California, people should always take steps to avoid mosquito bites, including removing standing water and wearing insect repellant when necessary. Californians should also be advised of international travel alerts for the countries where Zika virus is circulating.
"Although no one has contracted Zika virus in California, mosquito bites can still be harmful and the public should take steps to protect themselves,"" said Dr. Smith. "Help reduce the risk of mosquito bites by removing standing water from around your home and wearing mosquito repellant when appropriate."
As of Jan. 29, 2016, there are six confirmed cases of Zika virus in California, all of which were contracted when traveling in other countries with Zika virus outbreaks in 2013 (1), 2014 (3) and 2015 (2). CDPH will continue monitoring for any confirmed cases in California and will provide weekly updates every Friday. To protect patient confidentiality, specific locations of infected patients cannot be disclosed.
Zika virus is primarily transmitted to people by Aedes aegypti and Aedes albopictus mosquitoes, the same mosquitoes that can transmit dengue and chikungunya viruses. These mosquitoes - which are not native to California - have been identified in 12 California counties, although there are no known cases where the mosquitoes were carrying the Zika virus in this state. The six confirmed cases of Zika virus in California were acquired in other countries.
The Centers for Disease Control and Prevention (CDC) have issued a travel alert (Level 2-Practice Enhanced Precautions) for people traveling to regions and certain countries where Zika virus transmission is ongoing: American Samoa, Brazil, Colombia, Costa Rica, Curacao, El Salvador, French Guiana, Guatemala, Haiti, Honduras, Martinique, Mexico, Nicaragua, Panama, Paraguay, Suriname, Venezuela and Puerto Rico.
People traveling to these and other countries with known Zika virus risk should take steps to avoid being bitten by mosquitoes, including:
The CDC and CDPH have also issued guidance for pregnant women recommending they avoid countries where Zika virus is circulating. Pregnant women who cannot avoid travel to these countries should talk to their health care provider and take steps to avoid mosquito bites. The CDC and CDPH have also provided guidance for physicians on the evaluation of pregnant women and infants who may have been exposed to Zika virus.
Most people infected with Zika virus will not develop symptoms. If symptoms do develop, they are usually mild and include fever, rash and eye redness. If you have returned from an affected country and have fever with joint pain, rash within two weeks, or any other symptoms following your return; please contact your medical provider and tell the doctor where you have traveled. While there is no specific treatment for Zika virus disease, the best recommendations are supportive care, rest, fluids and fever relief.
There is concern that Zika virus may be transferred from a pregnant woman to her baby during pregnancy or delivery. Preliminary reports suggest that Zika virus may cause microcephaly (abnormal fetal brain development). This possibility has not been confirmed and is being actively investigated. CDPH has requested that health care providers report suspected Zika virus disease or associated conditions of microcephaly to local health departments. Local health departments will report cases to CDPH, which is coordinating referral of any specimens to CDC for diagnostic testing.

Chikungunya
Chikungunya virus (ChikV) (chik-un-GOON-ya) is transmitted by mosquitoes and causes joint pain and severe arthritis. It’s not normally fatal, but is extremely painful and symptoms can last for weeks or even months. In elderly people with compromised health, it can be a contributing factor to fatality.
