A growing number of schools are relaxing their restrictions and opening their doors to kids with coughs, sore throats and other symptoms.

This is a marked difference from the strict guidelines during the COVID-19 pandemic — when parents were advised to keep students home at any sign of illness.

California is one of the states that has relaxed its restrictions, as outlined on the state health department’s website.

Students may attend school or child care even if they have cough and cold symptoms, including a runny or stuffy nose, sneezing, congestion or body aches — with the exception of those who also have a fever, uncontrolled coughing fits or difficulty breathing.

Kids who have a headache or a stiff, painful neck may also come to school in the absence of a concussion or infection, according to the California Department of Public Health (CDPH).

The Golden State also allows kids to go to school with pink eye, as long as they don’t have vision problems, pain or injury.

Stomach pain is also OK, unless it involves an injury, vomiting, diarrhea or fever.

In some cases, students may even attend with an earache, diarrhea or wheezing, according to the health department’s guidelines.

California has also updated recommendations for individuals who have tested positive for COVID-19, the CDPH said in an email to Fox News Digital.

Although those who test positive are still advised to monitor symptoms and stay home if they have a fever and feel ill, the days of mandated quarantines appear to be over.

“Instead of staying home for a minimum of five days, individuals may return to work or school when they start to feel better, meaning that their symptoms are mild and improving, and they have not had a fever for a full day (24 hours) without the use of fever-reducing medication,” the CDPH told Fox News Digital. 

The department does still recommend 10 days of masking for students who have tested positive for COVID or have respiratory symptoms.

“Instead of staying home for a minimum of five days, individuals may return to work or school when they start to feel better.”

The state has also relaxed its COVID testing guidance.

“People who have been exposed to a confirmed case of COVID-19 and do not have COVID-19 symptoms are only recommended to test if they are at higher risk of severe disease and would benefit from treatment OR if they have contact with people who are at higher risk for severe COVID-19 infection,” the agency said.

“The reason for these changes is that we are now at a different point in time with reduced impacts from COVID-19 compared to prior years due to broad immunity from vaccination and/or natural infection, and readily available treatments for infected people,” the CDPH added.

The city of Boston, Massachusetts, also has relaxed its stay-at-home restrictions for sick kids.

On the Boston Public Schools website, the district states that students can attend with “common” respiratory infections.

“If the child does not have fever, does not appear to have decreased activity or other symptoms, it is not necessary for the child to stay home,” the guidance says.

Students may also attend if they have vomited once in the past 24 hours — but vomiting two or more times is grounds for staying home, the district stated.

Public health agencies’ recommendations

The Centers for Disease Control and Prevention (CDC) still adheres to stricter guidelines, stating that people with symptoms of respiratory or gastrointestinal infections, including cough, fever, sore throat, vomiting or diarrhea, should stay home.

The CDC also recommends that anyone who experiences symptoms of COVID-19 should be tested for the virus right away.

The American Academy of Pediatrics (AAP) states on its website that children should be kept home from school if they’ve had a fever above 101 degrees Fahrenheit within the past 24 hours, if they’ve had episodes of vomiting or diarrhea within the past 24 hours, or if they are not well enough to participate in class.

“If your child has been ill and is feeling better, but still wakes up with minor problems such like a runny nose or slight head­ache … you can send them to school if none of the three circumstances listed above is present,” the AAP stated. 

The AAP also warned of the dangers of “chronic absenteeism” — including lower literacy levels in young children and a higher risk of failing, getting suspended or dropping out among older students.

“Chronic absenteeism is also linked with teen substance use, as well as poor health as adults,” the organization added.

Doctors’ input on school policies

Dr. Shana Johnson, a physical medicine and rehabilitation physician in Scottsdale, Arizona, said that more relaxed school policies reflect “a better balance” between illness prevention and the impact of absences.

“Sick policies in schools have evolved to reflect the transition from a COVID public health emergency to COVID being endemic, or ever-present, in our communities,” she told Fox News Digital.

“Current policies better balance limiting the spread of disease with the harms of excessive absences.”

“Current policies better balance limiting the spread of disease with the harms of excessive absences, which include detriments to children’s education, social development and mental health,” she added.

The “hard-lined” COVID policies that were enacted in many states resulted in “tremendous harm” to children, Johnson said — including substantial learning loss, arrested social development and a spike in mental health crises.

“Now, four years following the emergence of COVID, we understand the virus better and have vaccines and treatments that reduce the severity of illness it causes,” she said. 

“Also, a large portion of the population has been exposed to COVID and has a level of protective immunity,” the doctor added. “All of the above lowers the risk of harm from the virus.”

Sick policies in schools are now more reflective of those in place before the pandemic, according to Johnson. 

“Before the pandemic, children attended school with a mild cold; they stayed home with moderate or severe symptoms such as fever and excessive cough,” she said.

“Some children have back-to-back colds for six months out of the year, especially younger children,” the doctor went on. “The hard-line policies would have these kids out of school for half the year.”

She added, “For a virus that causes mild symptoms in kids, missing half the year is not reasonable.”

Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Center and a Fox News medical contributor, said that kids with infectious-type symptoms, especially frequent upper respiratory symptoms, should not attend school at all.

“An occasional cough or sneeze or a confirmed allergy is one thing, but sore throat, cough, body aches or congestion are consistent with an ongoing contagion that is easily spread at school,” he warned. 

“Not only that, but there is the issue of the child recuperating and being at full strength.”

During what Siegel described as a particularly bad flu, RSV and COVID season, he stressed the importance of “doing our best to not spread these bugs at school.”
