A flu pill taken at home after exposure may shield the whole household, a new review finds

When one person in a home catches flu, everyone else holds their breath. A systematic review published in BMC Infectious Diseases weighed the evidence on baloxavir, a single-dose antiviral pill, and found that giving it to household contacts after exposure — doctors call this post-exposure prophylaxis — was linked to larger estimated reductions in household flu transmission than treating only the person who fell ill first. Treating the index patient still helped, with relative risk reductions of about 24–29% on most measures. It is a review of earlier trials rather than a new cure, but it sharpens a practical idea: protect the household, not just the patient.
