My sister asked me to ask this as she's not on mumsnet. (I know!) 
Her baby aged just under 10 months has a temperature. So do the family need to isolate? Temp is 38.6 previously 39. I don't know if the advice is same for under 1year?
Normally I assume the protocol is isolated until a negative test. But is it the same with a baby? Also how do you test a baby? Anyone got any experience of this?
Sorry if this is a stupid question! She's freaking out a bit and I said I'd ask here.
