Watching your child suffer from a bad case of strep throat is center-wrenching, only it's a nightmare when the infection occurs over and over.

There are many theories why some kids go strep throat repeatedly and lots of communication on how to prevent it. Merely according to a recent study, this could be something that can't be controlled.

According to the Centers for Disease Control and Prevention, strep throat is caused by a bacterial infection called grouping A Streptococcus.

When grouping A strep is a recurring problem, the issue can be utter misery. It's one reason why children may have their tonsils removed.

Now researchers at the La Jolla Institute for Immunology (LJI) take uncovered the starting time clues as to why some children may oftentimes contract group A strep.

In a study published in the journal Science Translational Medicine on Feb. six, researchers examined the surgically removed tonsils of 26 children between the ages of five and xviii years who had recurrent tonsillitis. They too looked at the tonsils of 39 children who had their tonsils removed for other reasons, such as sleep apnea.

What they found is that tonsils from kids with repeat infections had a genetically based poor immune response to group A strep bacteria. When the medical histories of these children were checked, the researchers confirmed the problem did run in some families.

The study found two specific gene variations that make it harder for someone who has them to fight strep throat. These gene variations were associated with the children who got recurrent tonsillitis.

The researchers as well found one cistron variation that protected against group A strep infection.

They hope this discovery volition atomic number 82 to a new vaccine that prevents recurring tonsillitis. This could hateful finding relief for young people without the risks of having a tonsillectomy.

"Having a vaccine that trains the allowed system in accelerate might be able to stimulate a protective response that tin prevent recurring bouts of tonsillitis," said the study's senior author, Shane Crotty, PhD, a professor in the sectionalisation of vaccine discovery at LJI, in a argument.

Strep throat may be a common childhood illness, simply it's still a serious one.

But ii weeks without treatment can exist enough for information technology to spread to other organs, like the kidneys or heart.

"More serious complications of untreated strep infection include acute rheumatic fever, which tin can bear upon the heart and cause kidney impairment," said Dr. Ashanti Wood, attention pediatrician at Mercy Medical Center in Baltimore.

But serious complications are rare, considering almost children are treated with antibiotics long before this tin happen. It's of import to accept the symptoms of strep pharynx seriously and seek medical attention promptly.

"Symptoms include sore throat, fever, and white pus pockets on very ruby tonsils in the back of the pharynx," said Woods, who wasn't associated with the study.

Wood says antibiotics are typically taken for about 10 days, depending on the person and the medication. Sometimes, antibiotics can be taken for only five days.

For many years, tonsillectomy was viewed as a solution to recurrent tonsillitis from strep. Merely the cure may come at the cost of respiratory health.

"Fifty years agone, a tonsillectomy was done at the drop of a hat," Ron Marino, Practice, vice chairman of pediatrics at NYU Winthrop Hospital, told Healthline. "Now a person has to take vii or viii strep infections in a flow of one to two years for tonsillectomy to be a viable pick."

And people may even so get strep infection after having their tonsils removed. There can exist complications, too.

"It'due south a surgical procedure, so you're going to the hospital. Anesthesia is involved with its own risks, and the procedure itself can crusade excess bleeding," Marino said.

Recent research that looked at over i million children establish there may exist long-term health risks from removing tonsils or adenoids (immune glands in the roof of the mouth).

These organs play an important role in the development and part of our immune systems.

According to the study, tonsillectomy was associated with near triple the long-term risk of upper respiratory tract diseases. Removing the adenoids was linked with an almost doubled risk of developing a chronic obstructive lung disorder afterward in life.

According to Forest, the circumstances surrounding recurrent strep throat usually involve close contact with others.

"This is why it's especially prevalent among households, schools, and mean solar day cares," he said.

Wood adds there are clear steps people can accept to lower their risk for strep infection.

"Proper manus-washing, covering of coughs, sneezes, and other respiratory droplets, and staying home when sick are means to reduce recurrent strep pharynx," he said.

Strep throat is a painful condition that's potentially life-threatening if not treated promptly. Research has found that children who have multiple strep infections in a twelvemonth may have a genetic trait that makes it hard for them to fight the infection.

Having identified the genes that make some people more susceptible to strep infection than others, researchers think it's possible to develop a vaccine that tin prevent repeat infections in this population.

While a tonsillectomy is 1 way to treat recurrent infections, information technology may not be the best solution. In addition to the adventure of complications from surgery, a recent report constitute that the procedure tin can increase long-term gamble of respiratory illness.

Strep throat is transmitted from person to person. To avoid this infection, practise good hand-washing and cover your mouth when coughing or sneezing. Avoid transmitting strep to others by staying home when you're ill.
