Parasites have got a lousy deal and a PR problem

In an increasingly politically correct world, there are scarcely any words or epithets that do not invite a pushback from activists who point out inherent biases in their use.

The ongoing pandemic has ensured that the word virus will take some time to be rehabilitated, but it is about time that someone speaks up for the billions of living creatures that are unthinkingly vilified by the disparaging use of words such as tick, slug, worm, leech, louse and, indeed, parasite.

As we strive to create a world where there is respect for all, there is a crying need to speak up for these marginalised creatures.


It is heartening that the journal Biological Conservation has devoted an entire issue to pointing out they are eco-warriors too and play a role in the survival of many of their host species. But they have a PR problem given that they have become involuntary stand-ins for allusions to freeloaders, bloodsuckers and bottom feeders.

The need for a global parasite conservation plan is as essential as, say, the Indian government’s recent announcement of projects to protect the dolphin and lion.

Just as cuddly and cute endangered species must be safeguarded, so must the parasites they carry, although people will take time to alter their attitude on this. Suitable alternatives to the current use of leech, worm, tick, slug and parasite would help.
