The reasons for the activity were not clear: either the virus is especially strong in cold weather, or frost weakens the immune system, so the body cannot resist the microbe.

Helen Foxman, an assistant professor at Yale University, conducted a study of the immune system: she tested the reaction of cells to rhinovirus at different temperatures.
