Britt Ehrhardt, public health communications officer for the Santa Clara County Public Health Department, said in an email that there is “no additional risk to the community” and that the person who visited Google is not linked to the other cases in Santa Clara county.
She said the county health department conducts contact investigations when suspected cases of measles are reported to determine the whereabouts of the infected person while they’ve been contagious and who they were in contact with. This allows health officials to inform those who have been in the places where there has been a possible measles exposure.
CNN contacted Google for this story but had not heard back as of Wednesday evening.
Measles is a highly contagious, vaccine-preventable respiratory illness characterized by a rash of flat red spots. Symptoms may include fever, cough, runny nose and watery eyes. Measles can also lead to death when complications become severe, according to the CDC.
Outbreaks have been linked, in part, to the anti-vaccination movement and the spread of misinformation about possible side effects of vaccines proliferating online.
Critics have called on tech companies to take more responsibility for public health disruptions occurring on their platforms.
Schiff addressed a similar letter to Facebook. In March, Facebook, the world’s largest social media site, took aim against anti-vaxers by lowering the ranking of groups and pages that spread misinformation about vaccinations in its News Feed and Search options.
