*
Two-week pause due to hurricanes.
**
For more information on the number samples for which IgG data was successfully collected see van den Hoogen et al. (15).
***
The large decrease in samples is due to the exclusion of participants recruited at church venues from further analyses due to practical and logistical restraints of this sentinel group (16).
