Pandemics happen often in the animal world, and not even little insects can avoid them. Researchers have discovered that one of the greatest creatures on the Earth, the humble bumble bee, practices social distancing during a pandemic. By keeping far apart it reduces the likelihood of other members of the group getting infected and prolonging the suffering of the whole. Bees figured this out thousands of years ago. That’s right even beings as small as the bee are smarter than anti-maskers.
Social insects are particularly vulnerable to pathogens and parasites owing to the dense network of contacts among highly related nestmates and the large amounts of food stored in a nest under relatively stable environmental conditions (1). To counteract disease pressure, social insects have evolved, in addition to individual immune responses, many forms of social immunity, i.e., strategies based on the cooperation of the individual group members (2). The latter occur at the behavioral, physiological, and organizational level and can act synergistically to avoid invasion, establishment, and replication of pathogens or parasites inside the colony (2, 3).
