You might remember getting chickenpox as a child or even as an adult.

The virus is best known for its red rash, blisters and itching. It also causes tiredness and fever.

Because chickenpox is contagious, siblings or students in the same classroom often spread the virus to one another. But researchers have found that the chickenpox virus may actually be a seasonal disease: Cases are discovered most often in the spring.

The study was published in the Proceedings of the National Academy of Sciences.

To investigate trends in chickenpox cases, researchers turned to the search engine Google. They looked at Google searches from 36 countries on five continents over an 11-year period, then confirmed their findings with clinical cases.

Previously, researchers have used Google to estimate and research rates of influenza.

Kevin Bakker is the lead author of the chickenpox study and a graduate student at the University of Michigan. He said countries that required a nationwide vaccination for chickenpox also saw a decrease in the number of Googles searches for “chickenpox.”

Dr. William Schaffner is an infectious disease expert at Vanderbilt University Medical Center in Nashville, Tennessee. He was not involved in the study, but he said the findings may be especially useful.

Schaffner thinks information will help in countries where the chickenpox vaccine is not common.

In the United States, chickenpox vaccinations began in 1996. Since then, the number of chickenpox cases declined by 92 percent, according to the Centers for Disease Control and Prevention.

The same virus that causes chickenpox can also cause a medical condition called shingles.
