BBlimey - don't fancy that much:

"Fungi of the genus Ophiocordyceps — so-called zombie ant fungi — need ants to complete their life cycle. When an ant comes across fungal spores while foraging, the fungus infects the insect and quickly spreads throughout its body.Fungal cells in the ant's head release chemicals that hijack the insect's central nervous system. The fungus forces the ant to climb up vegetation and clamp down onto a leaf or twig before killing its hapless drone. It then grows a spore-releasing stalk out of the back of the victim's head to infect more ants on the ground below"​

If you catch it you'll still be declared fit to work by DWP.
