If you look at the number of cases, the risk is quite low.

Officials said they expected the number of cases to increase.

The number of cases reported in the state was always small.

"Why didn't they give us a case number after what happened last night?"

By 1991, the total number of cases is likely to hit 270,000.

The total number of reported cases, however, was only 37.

But they said the number of such cases was no greater than in the past.

There are a significant number of cases where the answer is no.

County health officials report that the number of cases in 2001 was 646.

Perhaps a bit more ability in a number of cases.
