The most popular medical treatments for diverticulum infections are known as a sponge, a mask, and a bandage, but they all contain some risk, according to a new study.

Diverticulum infection, which causes painful blisters and pain on the skin, affects about 4.5 million people worldwide, according the Centers for Disease Control and Prevention.

About a third of those are children.

Divers are the most common source of diverticula infections.

There are also reports of other types of infections in children, including respiratory infections, skin infections and other skin conditions.

The new study looked at data from more than 6,000 adults and 1,000 children from four countries, including the United States, Australia, Canada and England.

The researchers compared their results with data from an earlier study that looked at diverticulent skin infections in patients who received a sponge treatment.

The researchers used the same criteria as the earlier study, which identified three main factors that could explain the difference between the three treatments: the severity of the infection, whether the patient had prior diverticulation, and whether the person had been treated with a mask or a bandaged mask.

The third factor, called the “risk factor,” was considered most important in predicting which treatment was better for diverts.

It’s based on whether there was a history of diverting or a history with a history.

The risk factor for diverting was less than 1 percent in all three countries, and the risk factor was lower in England.

The risk factor also had a stronger effect on the treatment of divert-associated erythema migrans, the authors wrote.

The study was published online May 1 in the journal PLOS ONE.
