That has essentially nothing to do with chickenpox.

Suppose the kid skins his knee. The scabs can allow skin bacteria to infect the child. This may present as a swelling around the scab. It can become life threatening as it can quickly progress to septicaemia (sepsis) in a matter of hours.

Yep. Same with mosquito bites, paper cuts, and slivers. You could DIE!!!!! Well, you could. You really could.

Think about: (a) the number of wounds, (b) the age of the child and (c) that they are already ill. Also consider the very serious consequences (death). That increase in the hazard and the potential for serious illness is what makes this a real risk.

In the UK we don't find it economic to vaccinate the whole population for chickenpox but if it's an option to pay for it then it would be sensible.
