FOR ALL IN-PERSON COLLOQUIUM ATTENDEES:

1. Everyone in attendance MUST wear a mask at all times when indoors. Cloth masks are unacceptable, surgical masks are barely passable, and we would like you to wear an N95 or equivalent mask.
2. No eating or drinking will be allowed indoors. Period. No tucking down your mask for a sip or a nibble. We will be serving lunchboxes outside and expecting everyone eating to do so in the ample outdoor spaces next to the conference center. If you want a drink or refreshment in the afternoon, please step outside. The reception at the end will be outside.
3. Unless you have had a COVID infection in the past 30 days, we expect everyone to have a negative COVID test by either of these methods: 1. A PCR or Color test collected the morning before the Colloquium (5/25) with a negative result returned by the start of the Colloquium, OR a rapid antigen test that can be done at home or work the morning of the Colloquium. We will have some rapid test kits available at the registration table for anyone unable to have a test done prior to arriving. TESTING IS ON AN HONOR SYSTEM. We will not be asking for documentation of test results.
4. If you have had a recent COVID infection, I regret that you cannot attend the Colloquium if it has been less than 10 days since the onset of symptoms or date of a positive test if asymptomatic, regardless of whether you may have had a subsequent negative antigen test on day 5 or thereafter. If it has been more than 10 days since onset of infection, you may attend the Colloquium without taking a pre-conference COVID antigen test if you meet the criteria listed at the bottom of my email.
5. [Addendum from Christine] All attendees are required to take the UCSF COVID health screener the morning of May 26th prior to arrival at the colloquium. UCSF employees and learners must take the daily health screening, which can be found on the following website link or through the UCSF app: https://www.ucsfhealth.org/daily-health-screening. Non-UCSF guests must also take the visitor daily health screening, which can be found through the following website link or through the UCSF mobile app: https://ucsf.co1.qualtrics.com/jfe/form/SV_d6elP7DE78J4oFT

Policy for people with a recent COVID infection

If a person has had a COVID infection within the past 30 days, they do not need to complete a COVID test just prior to the Colloquium and may attend the Colloquium in person if all the following conditions are met:

• The COVID illness was mild to moderate and did not require hospitalization, AND
• It has been at least 10 days since the onset of symptoms or the initial positive COVID test if asymptomatic (with first day of symptoms constituting day 0), AND
• At least 24 hours have passed since last fever without the use of fever-reducing medications (e.g., acetaminophen, ibuprofen, aspirin), AND
• 48 hours have passed since last episode of diarrhea, AND
• Symptoms are improving, AND
• No concurrent immunocompromising conditions; a person with an immunocompromising condition must wait 20 days after onset of illness or a positive test to be able to attend the Colloquium if all the other criteria above are also met
