Transmission risk 1. Goes up with humidity and down with more ventilation and warmer temperatures 2. Higher with smaller distances and fomites
Infectivity 3. Increases with greater viral inoculate (which goes up with more shedding), which is also greater with 4. reduced hygiene and direct contact with mucous membranes. Even at smaller inoculates, 5. an immune incompetent host has higher chances of infection. Happy to provide citations for anything you’re specifically curious about.
Thanks. The thing I’m ultimately looking for though is more like “at humidity X, your likelihood is Y”. I know roughly how the variables fit together, but not enough to decide “do I let a random person who might have covid into my house or not?”
Answer depends on several things
1. Where you met, temperature, humidity, degree of ventilation
2. Distance and intensity of interaction and exchange of fomites
3. Degree of infectivity (were they coughing and their viral shedding; where they are in illness course)
4. Hygiene, theirs and yours, including hygienic behaviors
5. Your level of immunity (are you already immune, are you immunocompromised, etc)
Do you have a sense on how it depends on any of those things?
