CHICAGO — It’s the story of the new infections, the new pathogens and the old infections.

The new infections have already surpassed those of the last few decades.

More than 4 million U.P. children have been infected in the last five years, according to the Centers for Disease Control and Prevention.

About 10 percent of those children have developed bacterial infections that are now severe or life-threatening.

Those infections can cause pneumonia and pneumonia-like symptoms.

The new bacteria, which can be deadly, can be transferred through close contact with infected blood, soil, water or food.

Some of the newly infected are getting better, but others are still battling the infection.

“We are now at a point in time where we are seeing increases in infections, and we’re seeing a rise in the number of people who are experiencing infections and they have died,” said Dr. Scott Gorton, a pediatrician in the Chicago Department of Public Health.

There is also evidence of a link between antibiotic use and more severe infections.

Dr. Gortons group analyzed data from the CDC and the University of Chicago to examine the incidence of antibiotic-resistant infections in the United States.

The group found that the average age of infection has increased from 14 to 17 years.

The percentage of people with antibiotic-resistance is also increasing.

And the number with infections has increased more dramatically than the number infected with the new bacteria.

In 2014, more than 11 million children were treated for bacteria, and the number treated with antibiotic drugs increased to 1.9 million, the CDC said.

The numbers of antibiotic prescriptions and prescriptions for antibiotic drugs has also increased significantly.

But there are other signs of the bacteria’s impact.

The CDC also said that the number and type of infections have increased.

There were 4.7 million new infections last year, a nearly 50 percent increase from the previous year.

And more people are getting sick.

About 2.7 percent of U.L.A. students have reported infections and a higher percentage of children who had a serious infection have been hospitalized.

In the last three years, the rate of infections among children in the Los Angeles area has increased by over 70 percent.

In a statement, the Los Angelas Unified School District said the new data shows that the district is working to provide more care and support for students who are at risk.
