The rubella outbreak in Macau doesn’t appear to be over yet. The most recent case involves a pregnant staff member of StarWorld Casino, reports GGRAsia.

This comes from a June 1 announcement from the Macau Health Bureau. The woman tested positive for rubella, also known as German measles, in a May 31 test. Doctors are closely monitoring the woman’s health, and keeping an eye on those she was in close contact with. She’s currently 14 weeks pregnant.

Galaxy Entertainment Group operates the StarWorld resort where the woman worked. The same resort was one of the hot spots for rubella outbreaks in April, when the outbreak first hit Macau hard with twelve staff infected in total.

Just in the months of April and May, Macau saw a total of 50 rubella cases, with many of them affecting casino staff. Besides StarWorld, staff at the MGM Macau and City of Dreams Cotai has also been impacted.
