Officials in Alabama have shut down an elementary school for the rest of the week and are conducting a deep clean after 773 of the school’s 974 students were absent Wednesday amid an explosive outbreak of gastrointestinal illness.

Local media reported that only 29 students were absent from Fairhope West Elementary School on Tuesday. However, the situation escalated quickly on Wednesday as word spread of a stomach bug going around the Gulf Coast school. A spokesperson for the county school district told AL.com that 773 students and 50 staff were absent Wednesday. It’s unclear how many of the absences were due to sickness or precaution.

Health officials are now investigating the cause of the gastrointestinal outbreak, collecting specimens for testing. So far, officials are working under the assumption that it is norovirus, a highly infectious gastrointestinal bug that can survive hand sanitizer and transmit easily from surfaces, food, and water. The symptoms of the unidentified illness align with norovirus: vomiting, diarrhea, abdominal cramps, and nausea.

On Wednesday, Baldwin County Schools Superintendent Eddie Tyler sent a message to parents saying that the county had decided to shut the school down for the rest of the week. “Due to the amount of staff and students who are absent, the number who are experiencing symptoms, and in an effort to help contain the contagion, we unfortunately need to shut the building down,” Tyler wrote. “While out, we will be conducting a deep cleaning of the school so when students return next week, it will be sanitized to the fullest extent.”

But local outlet WKRG reported Thursday that the outbreak has already spread beyond Fairhope West. On Thursday, 1,231 students from four other area schools were also absent, including 721 students at Fairhope East Elementary School, 136 at a third elementary school, 170 at a middle school, and 204 at a high school. These are in addition to the 974 students at Fairhope West who are out of school while it is shut down.

Norovirus activity is high across the country, with the northeastern region seeing the largest surge, according to surveillance by the Centers for Disease Control and Prevention. The agency notes that outbreaks are commonly linked to health care settings, restaurants or catered events, cruise ships, as well as schools and childcare centers. “Close quarters, shared spaces, and high-touch surfaces make it easy for norovirus to spread in schools,” the CDC points out.

In 2022, the COVID-19 pandemic flipped the script on standard norovirus outbreaks. People who were hoping to avoid close contact and share indoor air with strangers headed to the great outdoors, which led to a large outbreak of norovirus in the Grand Canyon.

Measles is “growing global threat,” CDC tells doctors in alert message

Alert —

Since December, there have been 23 measles cases in the US, including two outbreaks.

The Centers for Disease Control and Prevention is putting clinicians on alert about the growing risk of measles cases and outbreaks amid a global surge in transmission.

In an outreach message sent Thursday, the CDC told clinicians to look out for patients who have a rash accompanied by a fever and other symptoms of measles, as well as patients who have recently traveled to countries with ongoing measles outbreaks.

Between December 1, 2023, and January 23, 2024, there have been 23 confirmed measles cases in the US, including seven direct importations by international travelers and two outbreaks with more than five cases each, the CDC noted. Most of the cases were in unvaccinated children and teens.

Measles outbreaks in the US are typically sparked by unvaccinated or undervaccinated US residents who pick up the infection abroad and then, when they return, transmit the disease to pockets of their communities that are also unvaccinated or undervaccinated.

Globally and in the US, vaccination rates against measles—via the measles, mumps, and rubella vaccine (MMR)—have fallen in recent years due to pandemic-related health care disruption and vaccine hesitancy fueled by misinformation.

“The increased number of measles importations seen in recent weeks is reflective of a rise in global measles cases and a growing global threat from the disease,” the CDC’s outreach message, titled “Stay Alert for Measles Cases,” read.

According to data from the World Health Organization, the European region saw an over 40-fold rise in measles cases in 2023 as compared with 2022. The region tallied over 42,200 measles cases last year, compared with just 941 in 2022.

This week, the WHO reported a rapid escalation of measles cases in Kazakhstan (which the WHO considers part of the European region). Kazakhstan has recorded the highest incidence of measles cases in the region, with 13,677 cases in 2023. That corresponds to over 639 cases per million in the population. In the news release Tuesday, Kazakhstan’s health minister reported that there are “currently 2,167 children in hospital with measles, 27 of them in a serious condition.”

The outbreak is largely spurred by unvaccinated children who missed their routine immunizations during the pandemic. Sixty-five percent of the reported measles cases are in children under age 5, the WHO noted. The country is now trying to catch children up on their vaccines to curb the outbreak.

“Measles is highly infectious, but fortunately, can be effectively prevented through vaccination,” WHO’s Regional Director for Europe, Hans Henri P. Kluge, said in the news release. “I commend Kazakhstan for the urgent measures being taken to stop the spread of this dangerous disease.”

Meanwhile, measles is flaring up in many other places. Last week, the UK Health Security Agency warned of the potential for an ongoing measles outbreak to spread. As of January 18, there were 216 confirmed cases and 103 probable cases in the West Midlands region since October 2023. Authorities warned that any areas with low MMR vaccination rates are at risk of an outbreak.

The vast majority of Americans have received their MMR vaccines on schedule. In this case, the two standard, recommended doses are considered 97 percent effective against measles, and the protection is considered for life. But anyone who is unvaccinated or undervaccinated is at high risk of infection in the event of an exposure. The virus can linger in air space for up to two hours after an infected person leaves the area, the CDC notes, and is highly infectious—up to 90 percent of unvaccinated people exposed will fall ill. Once infected, people are infectious from four days before the telltale measles rash develops to four days afterward.
