Frequently Asked Questions

There are a number of factors that determine how serious a disease is:  

  • R0 Number an estimate of how many people will be infected by a person with the disease 

  • Incubation Timethe time from when a person was exposed to the disease and when they first show symptoms.  People can still transmit the disease to others during this time without even knowing they are sick. 

  • Hospitalization Rate: the percentage of people with the disease who will have severe illness that requires hospitalization.  

  • Case Fatality Rate: the percent of people with the disease who will die of it.  

To understand how serious COVID-19 is, it can be helpful to compare it to seasonal flu based on what we currently know about COVID-19:  




RO Number 


2 – 2.5 

Incubation Time 

1-4 days 

1 – 14 days 

Hospitalization Rate 



Case Fatality Rate 

.1% or less 

1 – 3.4%

INDOORS:  Yes, since they are currently ineligible for vaccines and are therefore "unvaccinated." This requirement is subject to forthcoming CDC guidance addressing schools and youth settings. "Youth settings" include K-12 schools and child care, and also cover day camps for youth, youth sports and other youth activities, including theater and music performances and band. The California Department of Public Health (CDPH) is closely monitoring anticipated updates from the CDC regarding K-12 and other youth settings and will update recommendations at that time.

OUTDOORS: In general, unvaccinated children and youth do not need to wear a mask outdoors, even if they cannot maintain physical distancing. However, per CDC recommendations, in areas of substantial to high transmission, people who are not fully vaccinated are encouraged to wear a mask in crowded outdoor settings or during activities that involve sustained close contact (including high-risk contact sports) with other people who are not fully vaccinated.


Marin County issued a Public Health Order for the wearing of face coverings in workplaces and public settings on August 2, 2021. Additional information around masking and limited exemptions can be found within the Order.

Yes. Currently, Pfizer is authorized for use with patients age 12 and above, and has received full FDA approval for use in patients age 16 and above.

At this time, alternative COVID-19 vaccines are not available for children and teens until more studies are completed. Such studies are underway in older children and are planned in younger children. COVID-19 is generally less severe in children than adults; nevertheless, the risk of severe disease in children with underlying medical conditions, and the general desire to prevent COVID-19 in children remain compelling reasons for vaccine studies in children.

If you received the Pfizer vaccine, then you should receive your second dose 21 days later.

If you received the Moderna vaccine, then you should received your second dose 28 days later.

Both injections must be from the same vaccine company (e.g. you cannot mix Moderna and Pfizer).  While the 1st injection begins priming the immune system, the 2nd solidifies and sustains a more robust immune response.  You are only partially protected with just one shot of Pfizer or Moderna.  If you miss your second dose appointment, schedule one as soon as you can.
