If a different strain of a named contagion exists, at the moment, once a creature, player etc. has one of those strains they won't pick up another.
It'd be better if in these situations that whichever is the stronger/nastier of the strains is transmitted in each direction.
This requires comparing 2 strains and selecting the strongest.
It also requires modification of the "transmit" methods in contagion, creature, artefact, and player
