/1 Thread about evidence & logical consistency of @RIVM advice on official FAQ (20-04).
I have some questions about evidence and possible inconsistencies.

/2 (Q1) @RIVM says vast majority of those who get #covid19 will not get it again. What is evidence for this?
I ask because @WHO says that it is very much unsure whether someone who has had covid19 is thereafter immune.

/3 (Q2) I find this difficult to follow.
It says:
(i) vast majority of those who get #covid19 will not get it again; and
(ii) those w/ mild symptoms develop fewer antibodies may get it.
However, it is assumed vast majority of those who get #covid19 have mild symptoms.

/4 Seems to be:
(i) Most Cs (infected) are immune;
(ii) Those Cs w/ mild symptoms might not be immune;
Seems to assume:
(iii) Most Cs have mild symptoms.
Is it then the case that most Cs are immune but might not be immune?
Or have I missed smthg (e.g. re general quantifiers)?

/5 (Q3) @RIVM recognises that *maybe* people without symptoms are contagious, but it:
>frequently assumes no or little asymptomatic transmission;
> undersells evidence on asymptomatic transmission (which is stronger than evidence for other claims)

Why?

Why?
/6 (Q4) @RIVM says no point in wearing a mask even if you are ill; says homemade masks are not effective.
What is evidence for this?
I ask because there is evidence against that homemade masks can be effective or even extremely effective

/7 (Q5) @RIVM this says that you may go outside after having no symptoms for 24 hours.
Other countries say 3 days (e.g. https://www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/steps-when-sick.html).
Does anyone know state of evidence on these matters (and has links)?
