Young infants with temperature higher than 400 °C are at increased risk for SBI (ncbi.nlm.nih.gov)

I think you may have a typo in your title.

Must be a mistake to say 400 in the conclusion. I see 40 thrown around, but 400 twice.

Also likely to spontaneously combust!

I'm not sure which is more likely: threecoins is pointing out how poor the proofreading is on the NIH website, or he himself is careless like so many who post on Hacker News.

That baby is too hot

I'm fairly certain an infant at 400°C has bigger problems than SBI.
