A number of hospitals have reintroduced masks in all departments. Also soap and water is better than any hand gel, particularly since norovirus is unaffected by alcohol gel. If I wear a mask, that doesn’t protect me from you, but it does protect you from me. The problem is that you can be infected and contagious up to 24 hours before you develop symptoms, as the incubation period is of the same order as the innate immune response (those first symptoms are actually due to your immune response). The other issue is that the vaccines cannot prevent you becoming infected neither can they prevent you from being infectious.

I would suggest that pregnant women are not at risk themselves, but their newborn will be. Pregnant women are vaccinated against pertussis and now RSV in the third trimester to provide passive antibody protection to the baby. Any neonate is at high risk from all respiratory tract infections, however preterm babies are at a significantly higher risk as their airways are very narrow. Their innate immune system is also likely to be underdeveloped.
