Doznes of Texas spring breakers test positive for coronavirus

A group of spring breakers who defied public officials' coronavirus warnings are now dealing with the consequences of not canceling non-essential travel and practicing social distancing. About 70 people in their 20s traveled in a large group from Austin, Texas, to Cabo San Lucas in Mexico in mid-March. On Tuesday, the Austin Public Health Department announced 28 of them have tested positive for COVID-19. By Wednesday night, the number infected had risen to 44.

The group flew to Mexico on a charter flight about a week and a half ago and some of the vacationers returned on separate commercial flights, the City of Austin said in a press release.

"Austin Public Health and UT Health Austin and University Health Services have made contact with every spring breaker onboard the plane using flight manifests from the Center for Disease Control and Prevention (CDC)," the press release reads, adding that the "confirmed cases are self-isolating at this time. Others are under quarantine while being monitored and tested."

Four of the confirmed cases did not present any symptoms, officials said.

According to the University of Texas, many of those on the trip were UT Austin students, with all of the 44 positive cases being students, CBS Austin reports.

A federal travel advisory was not in place for Mexico when the students traveled there; however the city says all residents should follow the CDC's recommendations that all non-essential international travel should be avoided. "A leisure vacation of any kind is not considered essential," the press release reads.

Nearly half of the positive COVID-19 cases in Austin-Travis County are in people between the ages of 20 and 40, the city says. The for his remarks. "I would like to sincerely apologize for the insensitive comment I made in regards to COVID-19 while I was on spring break," he said. "I wasn't aware of the severity of my actions and comments. Like many others, I have elderly people who I adore more than anything in the world and other members who are at risk, and I understand how concerning this disease is for us all."

Many millennials and even younger people may be ignoring these social distancing warnings because they think coronavirus won't affect them — but they're wrong. While patients age 60 or older or those with underlying health issues face the highest risk of death from the virus, younger people are also getting seriously ill. The CDC reports 20% of those hospitalized with the virus are in the 20-to-44 age group.

"This big idea of social distancing, we can't hammer it home enough," CBS News medical contributor Dr. Tara Narula said on "CBS This Morning" in March. "This comes down to something we call the reproduction factor — that's how infectious I am. So if I [hypothetically] have the disease, I can spread it, we think with coronavirus, to three people."

"That reproduction number is affected by the virus properties itself, who is susceptible, but also the duration of contact with individuals and the number of people you contact," Narula said. Decreasing the number of people you contact and the duration can significantly slow down the spread of the virus, she said.
