Some studies, especially in the southern hemisphere, were quite sold on ivermectin, but there is a lot of suspicion that the good results are actually due to worms increasing the risk of Covid death.

So if you're from the US and your aunt from Florida/Louisiana tells you Ivermectin work, you can honestly respond: Yes.

Is there any reason why worms would increase the severe morbidity/death rate?

The only thing I can think off is that (some) parasites tend to have a suppressive impact on the immune system but it also seem that could also prevent the cytokine storm that initially was reported as a major cause of severe illness and death.
