 How Diseases are Seasonal: Viruses for Winter, Bacteria for Summer

A new study has revealed the "seasonal factor" affecting the onset of infectious diseases. It claims that while winter witnesses a spurt in viral infections such as influenza or common cold, summers belong to 'bacterial infections'.

Researchers from Oregon State University have discovered that serious infections caused by gram-negative bacteria can go up as much as 17 percent with every 10 degree increase in seasonal temperature.

The study suggests that the incidence of some of the illnesses might be up to 46 percent higher in summer than in winter.

"Everyone knows there is a seasonality to some viral infections such as influenza or the common cold, but we're now finding that some of these bacterial infections peak in the heat of summer," said Jessina McGregor, an assistant professor in the College of Pharmacy at Oregon State University

"Gram-negative bacteria are a frequent cause of urinary tract, gastrointestinal and respiratory infections, as well as more serious things like pneumonia, wound or blood infections," she added.

The researchers suggest that identifying these seasonal trends can help improve disease diagnosis, prompt treatments and better interventions to prevent the infections.

During the study, the researchers examined infections caused by several gram-negative bacteria, including E. coli, Pseudomonas aeruginosa, E. cloacae, and Acinetobacter baumannii.

The greatest increases in infection due to higher temperatures were found with P. aeruginosa, a common cause of burn, external ear, urinary tract and lung infections; and A. baumannii, an opportunistic pathogen that can cause death and serious illnesses, particularly in people with compromised immune systems.

The researchers believe P. aeruginosa is an aquatic organism, and infections caused by it could be linked to more people swimming in lakes or pools during the summer.

"Bacterial infections in general have been rising for some time, probably due at least in part to increased antibiotic resistance," said McGregor.

"The more we can learn about what is causing them and when they are most likely to occur, the better we can treat or prevent them," she added.

"Regardless of the mechanisms responsible for infections, recognition of the link between the physical environment and the incidences of pathogenic infection could aid in infection prevention interventions or the selection of optimal empirical antimicrobial therapy," the researchers wrote in their report.

The study is published in Infection Control and Hospital Epidemiology, a professional journal.
