As of Dec. 1, there have been 619 cases in California, with 10 just this month, according to the Stanislaus County Health Services Agency. So far in California, Zika virus infections have been documented only in people who were infected while traveling to areas with ongoing Zika transmission, through sexual contact with an infected traveler, or through maternal-fetal transmission during pregnancy.
Zika is carried by the Aedes aegypti mosquito, which is known to be in the San Joaquin Valley. The Centers for Disease Control and Prevention says this type of mosquito is an aggressive day biter, but also known to bite at night. An Aedes mosquito can only transmit Zika virus after it bites a person who has this virus in their blood. Most people testing positive for Zika will have mild to no symptoms. The most common symptoms include fever, rash, conjunctivitis (red eyes), and joint pain and begin three to seven days after being bitten. Severe illness requires supportive car…
Colombia has confirmed the first three deaths of patients infected with the Zika virus
Health officials in the country’s second city, Medellín, reported on Thursday that a man and a woman admitted from other areas died in the past week after presenting symptoms of Guillain-Barré, which include muscle weakness and paralysis. Another man died in late November. All three tested positive for the Zika virus.
Gaviria said Colombia has registered about 100 cases of GBS that are believed to be related to the Zika virus. Overall, Colombia has recorded more than 20,500 confirmed cases of Zika infection.“Mortality is high,” Gaviria said in a phone interview a day after meeting with health ministers from around Latin America in Montevideo to address the crisis caused by the spread of Zika.
L.A. County officials said Thursday that a woman had been infected with the Zika virus by her partner in the first case of sexually transmitted Zika virus in the county.
A man who lives in L.A. County traveled to Mexico and became infected with the Zika virus in early November, and shortly afterward his female partner, who didn’t travel to Mexico, also developed the infection, officials said.“This case is a reminder to take precautions during sex or avoid sex if you or your partner have traveled to an area with risk of Zika,” said Dr. Jeffrey Gunzenhauser, L.A. County’s interim health officer.Since 2015, there have been 122 cases of Zika infection in L.A.

County or elsewhere in California.In California overall, there have been 619 cases of Zika virus since 2015, eight of which were sexually transmit…
the Zika virus can develop a number of serious neurological conditions, a new study finds
Until now, the most troubling Zika-related illness in adults has been Guillain-Barre syndrome, which causes muscle weakness and paralysis.
A review of 35 Zika-infected patients in Brazil with neurological symptoms found that most had Guillain-Barre. But other neurological conditions were also discovered, most often inflammation and swelling of the brain and spinal cord.
"Now we're realizing that adults may be impacted," he said. "There are clinical implications, as was well demonstrated in this paper."
During the Zika epidemic in Brazil in 2015-16, admissions at this hospital for Guillain-Barre increased more than fivefold, Frontera said. On average, doctors there saw one case of Guillain-Barre a month before the outbreak; that rose to more than five a month as Zika raged through the country.
