CDC’s New ’15 Minutes of Exposure’ Guidance
The previous guidance suggested that a close contact occurred when a person was within six feet of an infectious individual for 15 consecutive minutes. Now, the CDC is acknowledging that even brief contact can lead to transmission. Specifically, the new guidance suggests that those spending a total of 15 minutes of contact with an infectious person over the course of a 24-hour period should be considered in close contact.The new guidance suggests that there is more of a dose-response relationship between viral exposure and risk of disease. Which is to say, the more virus you are exposed to, the higher your risk, even if the exposure doesn’t happen all at once.This change by CDC suggests that we need to be more careful about brief interactions – for example, in the office or at school.The importance of wearing masks at all times to protect others has never been more clear,even a brief, unmasked encounter could spread the virus.
face coverings (nose &mouth) should be part of new normal.
Smoking in any form at this time should be banned in public places as it may increase the spread of virus
Teamwork and feeling of openness is important for winning this Corona war
