“this cold virus the most important is, flu virus Is it a virus? relatively common; generally Víctor Jiménez Cid, professor at the Department of Microbiology and Parasitology at the Complutense University of Madrid, detailed the impact of autumn and winter on humans.

“he cold is essential because reduce A series of defense of our organismmaking it easier to get infected by any of these viruses. enter and cause infection», highlighted Dr. Diego García Martinez de Artola, spokesman for the organization Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC)

factors that increase infectivity

this increased factors he risk of infection The incidence of these diseases is usually low temperaturethis low relative humidityhe overcrowding exist interior spacea major contact directly between people in offices and other spaces Public transit and lack of ventilation exist working environment Or at home.

«Breathing cold air slows down some of the defensive functions of our airways, but The most decisive thing is that we conduct more of our social lives indoors», emphasizing that Jimenez should spend less time outdoors and spend more time in enclosed spaces.
