The US Department of Health and Human Services declared that govt mail carriers would deliver antibiotics to people in the US in case of an anthrax attack. The mail carriers would be escorted by the local police. Supplies for a few days prescribed dose of antibiotics shall be delivered at the residence of the affected areas. 

Seattle, Philadelphia and Boston have already been tested for the new system. A pilot program will soon begin in Minneapolis – St Paul in Minnesota.

HHS Secretary Mike Leavitt, “The intentional release of anthrax spores is one of the most significant biological threats we face.”

"We have stockpiled millions of doses of antibiotics -- enough to meet the needs of several large cities. But terrorists attack without warning, and many people could fall ill from inhalation anthrax before we get them the stockpiled drugs," Leavitt added.

"We have found letter carriers to be the surest way of getting pills to whole communities of people anywhere in the country," Leavitt said. 

After supplying the initial stock of the antibiotics, public health authorities would set up centers to replenish supply in the infected areas.
