Best Answer

You use at risk.

At risk is an idiom that means "to be in a situation where something unpleasant might happen." (Collins Dictionary)

For example (nhlbi.nih.gov):

However, two age groups are at greater risk of developing pneumonia

If you check .gov sites, you can see, they usually say someone is "at risk of developing" a disease and not "in risk of developing" a disease.

"In risk" is not wrong, but the idiomatic usage is "at risk."
