The increased attention of the international community to the occurrence of repeated outbreaks of avian influenza infections worldwide has highlighted several knowledge gaps in the field. Among these, within the EU funded project Fluresist, we addressed the resistance of selected H7 subtype strains at 37°C. In general terms resistance was greater than expected, although some strains were more resistant than others, remaining viable after 15 days at 37°C. Our results should be considered when designing guidelines for outbreak management.
