Anyone got any thoughts on why Van is constantly getting site infections. We've changed nothing about how we do his sites yet suddenly, they're all ending up with pus. We get on to them quickly, they don't need antibiotics and heal nicely and once the site is out his numbers get back to normal pretty quickly. We use a metal site, change it every 3 days immediatly after a shower. Dont' use a prep (we found it game him infections) and have been fine for 4 years but suddenly, it all changes. Could it be summer and swimming? How much infection can find its way in from the outside world when a site is in. Just thinking about all the public pools he's been in over the holidays. Any thoughts why it's all gone haywire?
