Relevant: The Only Social Network Built On Trust

*The US government’s Centre for Disease Control (CDC) has made official the emerging scientific evidence on Coronavirus transmission:* 1. *Very low risk* of transmission from surfaces. 2. *Very low risk* from outdoor activities. 3. *Very HIGH risk* from gatherings in enclosed spaces like offices, religious places, cinema halls, gyms or theatres. These findings that have been emerging for a while need to be applied by people to manage the situation in the best possible manner. Time to reduce panic about surface transmission, and not be too eager to go back to office. *LATEST FROM CDC, USA* *Q - Who is expected to catch CORONAVIRUS?* *Q - What does it take to infect?* TO SUCCESSFULLY INFECT A PERSON, THE VIRUS NEEDS A DOSE OF ~1000 VIRAL PARTICLES (vp) The typical environmental spread of activities: 😷 Breath: ~20 vp/minute 😷 Speaking: ~200 vp/minute 😷 Cough: ~200 million vp (enough of these may remain in air for hours in a poorly ventilated environment) 😷 Sneeze: ~200 million vp *FORMULA* SUCCESSFUL INFECTION = (Exposure to Virus x Time) *SCENARIOS* 1. Being in vicinity of someone (with 6 ft distancing): Low risk if limit to less than 45 minutes 2. Talking to someone face to face (with mask): Low risk if limit to less than 4 minutes 3. Someone passing you by, like walking/jogging/cycling: Low risk 4. Well-ventilated spaces, with distancing: Low risk (limit duration) 5. Grocery shopping: Medium risk (can reduce to low by limiting time and following hygiene) 6. Indoor spaces: HIGH RISK 7. Public Bathrooms/Common areas: HIGH FOMITE/SURFACE TRANSFER RISK 8. Restaurants: HIGH RISK (can be reduced to medium risk by surface touch awareness) 9. Workplaces/Schools (even with social distancing): VERY HIGH RISK, including high fomite transfer risk 10. Parties/Weddings: VERY HIGH RISK 11. Business networking/conferences: VERY HIGH RISK 12. Arenas/Concerts/Cinemas: VERY HIGH RISK *RISK FACTORS* The bottom line factors you can use to calculate your risk are: - indoors vs outdoors - narrow spaces vs large, ventilated spaces - high people density vs low people density - longer exposure vs brief exposure The risks will be higher for former scenarios. *STAY SAFE*
