2-week Individual Risk calculated as ${multipleRisk(OneTimeRisk,Repetitions).toLocaleString(undefined, { style: "percent", maximumSignificantDigits: 3 })}

or about 1 in ${(Math.trunc(1/(multipleRisk(OneTimeRisk,Repetitions)))).toLocaleString()} chance.

Recommendation: Anything over 0.1% is considered moderate risk. Over 1% is risky. Over 4% is severe risk.

This assumes that each person in the room has ${(percentCurrentlyInfected).toLocaleString(undefined, { style: "percent", maximumSignificantDigits: 3 })} chance of carrying and spreading the virus. Your community may be higher or lower.

Overall, the number of expected cases is ${(outputTotalCases2Weeks).toLocaleString(undefined, {maximumSignificantDigits: 3})} over 2 weeks among the ${numberOfPeopleInSpace} people in the space

You gave a time duration of ZZZZ. Every hour, you are breathing NNN times. That comes out to ZZ gallons. If the air in those ZZZ gallons contains COVID particles, that will lead to possible illness. ## Activities and protections Using the parameters given below, in particular: * Activity: list * Protection/Masks: list * Time emitters emitting: list * Ventilation: list this means that the chance a dose of virus is in a gallon of air is QUANTACONCENTRATION. If you don't wear a mask, and only considering the aerosol risk (see aerosol risk vs droplet risk link), you would have a ZZZZ percent chance of getting sick if one person in the room is sick. Since you are wearing a mask (go you!), your risk is reduced to ZZZZ percent. ## Is someone infected in the room? There is generally no way to directly know if someone in the room is already infected just by looking at them. The majority of infections appear to come from people who do not show symptoms (presymptomatic or asymptomatic). Therefore, we have to use probability to estimate how many of the people have the infection. From the infectivity in the community, ${percentCurrentlyInfected} was used. Adjust to match your community by using the slider below. ## Overall Summary If someone is infected, your chance of infection (called secondary infection) is ZZZZ. This takes into account you wearing a mask of ZZZ protection efficiency. The chance someone is infected is ZZZZ. So, the combined chance that someone is infected AND you get infected is ZZZZ1 * ZZZZ2 = ZZZZZ3. `35:[] 2f:{"title":" Covid Individual Event Risk Calculator v0.2","cells":[{"id":0,"value":"html`
