Anyone else getting forwarded that ******** info claiming to be from Stanford hospital? Just had to tell my sister in law that she was spreading potentially dangerous info. Few others in work also received it from otherwise intelligent people.
Apparently you only need to hold your breath for 10 secs to prove that you haven't contracted it!!
Apparently the ten seconds is accurate, but it's not proving you haven't got it. It's giving an indication of whether you are developing a cough connected with corona virus before you get it. It doesn't account for any other symptoms or if you are infected.
