Tracking individual swine flu cases is too overwhelming for countries where the virus is spreading widely, the agency says in a statement. WHO will no longer issue global totals of swine flu cases, although it will continue to track the global epidemic.

WHO says countries should look for signs the virus is mutating, such as changes in the way swine flu is spreading, surges in hospital visits or more severe cases.

The agency asks countries to report their first confirmed cases, then provide weekly case numbers with a description of their outbreaks.

WHO had reported nearly 95,000 cases including 429 deaths worldwide. But the numbers are outdated, with Britain estimating it had 55,000 new cases last week alone.

There are now 93 cases of the H1N1 flu virus throughout Ohio — up from 63 a week ago.

Twenty-five Ohio counties have reported residents diagnosed with the flu virus — known as swine flu — including three counties in the Dayton area.

Montgomery County has three cases, Clark County has six cases and Butler County has two.

In Ohio, Cuyahoga County has the most diagnosed cases with 24.

There are also 43 suspected cases throughout the state and three probable cases.

The virus was declared a global pandemic two weeks ago by the World Health Organization. The last pandemic, in 1968, originated in China and killed 1 million people.

There are now about 60,000 cases of H1N1 globally, with the U.S. having the most with 21,449 cases and 87 deaths. Every state, as well as Washington, D.C., and Puerto Rico have had diagnosed cases, according to the federal Centers for Disease Control and Prevention. Mexico, where the strain originated, has 8,279 cases but the most deaths with 116.

In the United States, the most deaths have occurred in New York with 35, followed by California with 16 and Texas and Utah with 10.

Seven children and three adults at a summer camp in Minnesota for kids with muscular dystrophy contracted swine flu this month, contributing to the decision by the national Muscular Dystrophy Association to cancel dozens of its remaining summer camps across the country.

The national MDA also reported swine flu cases at camps in Utah and Pennsylvania. None was fatal.

The MDA of Minnesota wrapped up the one-week session at Camp Courage on Maple Lake, about 50 miles west of the Twin Cities, on June 12.

The Minnesota camp ran the full week because “the cases didn’t show up until the camp was complete,” MDA national spokesman Bob Mackle said Saturday. “None of the cases in Minnesota required hospitalization. They weren’t severe.”

All 10 people who fell ill — among them three adult MDA staff members or volunteers — have recovered, Mackle said.

Golden Valley-based Courage Center, the rehabilitation organization that operates Camp Courage and a similar facility on Lake George in northern Minnesota, “has no intention of closing either of our camps” because of the outbreak, spokeswoman Mary Small said Saturday night.

Small said that four of the 10 who fell ill were in the same cabin. She said camp officials were notified of the outbreak three days after the MDA group left, and the entire camp was immediately “sanitized,” a disinfecting process that it already does on a regular basis. Other groups that use the facility were notified of the outbreak, but there were no cancellations, she said.

The state Health Department confirmed the “cluster of cases” coming from the MDA camp. “We are investigating it with the camp,” said John Linc Stine, assistant commissioner for health protection.
