Britain's health minister Andy Burnham says the country could have 100,000 new cases of swine flu every day by August.

The World Health Organization has said that 2 billion people could be infected with swine flu worldwide. Most cases are mild and require no medical treatment to get better. More than 77,000 cases, including 332 deaths, have been reported worldwide.

Burnham announced in the House of Commons Thursday that Britain was going to stop liberally giving out Tamiflu to all cases and their contacts, and that the antiviral would only be used to treat patients. Many experts have criticized Britain's approach to the outbreak for wasting resources and drugs.
