So far this year, she said, the infection rate is running at 80 percent.

For the age group overall, the new infection rate was 4.4 percent.

The infection rate there is now one new person per minute.

Southern African infection rates are 30 times those in the north, he said.

Infection rates for people under 20 held steady at about 16 percent.

Health officials say the infection rate may surge past 30 percent if nothing is done.

Another potential reason is a high infection rate in Haiti.

Without that first line of defense, experts can only guess at the reasons for the low infection rate.

Haiti does not provide data but probably also has a high infection rate.

However, subsequent research has shown a much lower infection rate.

The disease has a morbidity rate of 2-10%, and affects 100-500 people annually.

"The South Carolina virus had a zero morbidity rate."

Second, mortality rates have sometimes been used as a proxy for morbidity rates.

What does the maternal mortality and morbidity rate mean?

There is no comparable paternal mortality or morbidity rate.

Surprisingly, the morbidity rate was low, while mortalities were nonexistent.

In endemic areas the morbidity rate is 70-90% and the mortality rate is 5-10%.

The morbidity rate has slowed by nearly 72.0091 percent!

At least two million people annually die of these diseases, and the morbidity rates are many times higher still.

There is a low morbidity rate, and no complications have been documented, other than those typical of any type of back surgery.
