I would like to know the risk to my husband and possible mitigation approaches regarding an upcoming visit by my daughter's family for a 1 week visit starting April 1. Her husband came down with Covid after a trip. He first felt symptoms on March 22. He tested positive on March 25 and immediately started on Paxlovid and isolated from the family. He tested negative on March 27. My daughter and 2 preschool children are symptom free and test negative. The entire family is fully vaccinated. My husband is 77 years old, has in-remission CLL, is fully vaccinated and has been getting gamma globulin infusions (last one 1 week ago). He had Covid last June and had to be hospitalized twice. He is fully recovered now. We would like to know how risky a visit would be from my daughters family provided they all remain asymptomatic and test negative the day before coming. Thank you.
Testing negative is the best strategy, however since you could be exposed to Covid while en route (e.g., air travel) you may need to consider re-testing at designated intervals during your visit. Covid levels are relatively low throughout the U.S., but low is not zero and for some people this could be interpreted as “risk”. Having the visiting family members wearing a well-fitting mask can help to further mitigate the risk of transmitting Covid to your husband. You may also reduce risk through increasing ventilation by opening windows and allowing more outdoor air into the enclosed indoor spaces. If springtime allergens are a problem for family members, then you can alternatively use HEPA filtration of air to improve indoor air quality.
