Cold & Flu: When Are You Most Contagious?

About this video

In this short clip, Huberman explains the contagious window for colds and flu. He says people begin shedding virus, and are therefore contagious, about 24 hours before their first symptoms appear, so they can spread the virus while feeling fine. Huberman adds that anyone still showing symptoms remains contagious, and that with flu, people are most contagious during the three days when they feel worst, with fever, coughing, sneezing and headache at their peak.

Key takeaways

• Huberman says people are contagious about 24 hours before cold or flu symptoms begin.
• Huberman says you remain contagious while you still have symptoms.
• Huberman says flu is most contagious during the three days symptoms feel worst.
