Thank you all for your advice, I am ringing the Cat and Rabbit first thing in the morning. I panic a bit over the girls, I suffer with anxiety and didn't sleep last night worrying about Abigail. Sorry I will keep all information on this thread. x
Take a deep breath!
The time between infection and actual outbreak is 10-14 days. This means that you have also got all this time to break the cycle and stop any further spread (including any potential transmission to yourself) as long as you can start ringworm treatment at some point during this period.
With oral (if not cheap) itrafungol you usually get on top of the acute symptoms in the affected piggy within a week; but it is worth the expense as treatment is a lot less stressful than baths for everybody every three days!
Give the companion and yourself an all body nizoral shampoo during this time to stop any spores that may have landed on your bodies from causing an infection. Alternatively give the companion some itrafungol, too, and only yourself a nizoral bath.
With another deep clean once the fungal has been stopped and another nizoral all-body shampoo for all your piggies and yourself once the itrafungol has done its work on your affected piggy, you also make sure that there are no tiny spores left anywhere (including in the fur coat) that can be carried around and cause any later outbreaks, so you all can start with a totally spore-free clean slate into the observation period.
With the practical tips in our ringworm hygiene guide you can get on top of it within 1-2 weeks with another 2 weeks observation period afterwards to make sure that there is no further outbreak. Please take the time to read the guide at every stage. I have made it as clear and precise as possible.
If it helps you, I have managed to keep my last outbreak two years ago in a room of 30 piggies to just the one affected piggy with practising my own ringworm care tips, so I know from my own experience that it can be done!
Ringworm: Hygiene And Pictures
Most of the ringworm trouble in pet guinea pigs comes from inadequate treatment and lack of hygiene because it is the single most contagious issue between species. If you get the two things right within your 'period of grace' (i.e. the time between infection and acute outbreak), you can get on top of it comparatively easily with the application of a little application - which is a pain in the neck but it is doable as long as you follow our advice and close off all possible ways the spores can be passed on.
I hope that this makes sense to you and calms you down a bit?
