Collin County officials on Monday identified the second confirmed case of measles in the county, according to the Department of Health Services.
The measles sufferer spent "little time" in public while she was contagious at the Kroger on North Preston Road Friday between 9:00 and 10:00, depending on the county.
Collin County Health Services stated that the person did not report being contagious in other public places.
The first confirmed case of measles in north Texas in 2019 occurred in Denton County in early February.
Measles is highly contagious and is transmitted primarily from person to person by air, said Collin County Health Services. People with measles are contagious from four days before the onset of symptoms to four after the onset of symptoms.
Officials urged people who thought they were infected with measles to call their doctor or emergency care facility before they arrived so that health care providers could take the appropriate precautionary measures.
