Is it stressful to be surrounded by infected individuals, even if you're not infected yourself? Might this even increase mortality (if others could have performed work but now won't)? Sounds plausible, but we don't have evidence from very many systems. Here's one! academic.oup.com/evolut/advan...

Parasite prevalence in a social host has colony-wide impacts on transcriptional activity and survival

Abstract. Parasites pose significant challenges not only to individual hosts but also to entire social groups. We investigated the effects of parasitism by

Examining the correlation between body condition and parasite infections is a common approach for identifying the negative effects of parasites, but causality is unknown (parasites reduced body condition? poor body condition caused infections?)(continued).
