Ever since COVID-19 hit, things have changed for people the world over. Many governments enforced lockdowns on their citizens, certain products are harder to get than before (looking at you toilet paper hoarders), and there has been an enormous and terrible loss of life. A wet market in China is suspected to be the source of the outbreak, but one thing to consider as we move forward is that the risk of another outbreak from other animal markets remains high.

Deer mice like the one above are small parts of a complex and interconnected world. When two pieces of their world work against them simultaneously, how are these mice affected? (Image Credit: USDA, CC BY 2.0).

Parasites are bad news for the organisms that host them. Some parasites are so bad, they can actually make the host kill itself. Despite these clear and obvious costs to infection, the common consensus is that parasites are not too big of a deal for the host, because of how rare parasitic infection is on average. For example, in my research system only one in ten animals have parasites.
But when these ill-effects of parasitism are combined with other detrimental factors, such as a harsh environment, an organism with parasites is forced to deal with not one but two stressors. The authors of today’s paper were interested in how these effects of parasites may change depending on the environment that the host lived in.
Parasites like this leech can be found all over the world, and anyone growing up near freshwater knows to check for them. But many consider these animals “gross”, so how can we motivate the public and scientists to care about them? (Image credit: John Douglas, CC BY-SA 2.0, Image Cropped)
