One positive case means significant chance others are infected, warn scientists amid Omicron wave
Whole households should cancel gatherings and visits to events if a single member tests positive for Covid, because the others are probably infected too, according to government scientific advisers.
The highly transmissible Omicron variant spreads so fast that even if only one person in a house or a close-knit work team tests positive on a lateral flow device, there is a “significant chance that others are already infected”, the scientists warn.
