Google Mountain View, CA headquarter measles outbreak

Google employees may have been exposed to measles after a San Mateo resident diagnosed with the virus "spent some time" at the Mountain View headquarters.

Dr. Sara Cody, Santa Clara County health officer and public health director, would not confirm that the San Mateo resident was an employee of Google.

"The person was a resident of San Mateo County, but the exposure occurred in Santa Clara (County), so we took the lead in ensuring that anyone in Santa Clara County got proper follow," Cody said at a press conference Wednesday.

Buzzfeed reported that a physician at Google had a letter to employees who had visited the tech giant's office at 1295 Charleston Road on April 4 had been diagnosed with measles.

"We have been working with the Santa Clara County Public Health Depart- ment and they would like to share this measles advisory, which contains information on measles, exposure risks, and actions to be taken," Buzzfeed reported that physician wrote to employees on April 13.

So far this year, four measles cases have been confirmed in Santa Clara County and San Mateo County respectively.

In Santa Clara County, vaccination rates among children are high, with over 97 percent on average in public schools and over 94 percent on average in private schools, according to the county's website.

Therefore, Cody said the vast majority of residents do not have anything to be concerned about. "It's unusual to see the spread of the disease because of these vaccinations," she said.

"The reason county health departments are so seriously because of infants," Cody said. "Infants are usually not vaccinated until they are a year old, so the way to protect infants is to ensure the community is vaccinated."

At least 555 measles cases, including 21 in California, have been confirmed in this country – the second highest number of cases reported in a single year since the disease was declared domestically eradicated in 2000, according to the Centers for Disease Control .

The CDC attributes the uptick in measles cases to the international community and to the United States.
