premise: The frequency of MRSA bemg given as the cause of death on death certificates has been increasng significantly for several years. MRSA 1s an infection-causing bacterium that has developed a resistance to penicillin and many other antibiotics. MRSA infections represent a particular danger for hospital patients with weakened immune systems or open wounds. Scientific trials are testing whether MRSA develops resistance after exposure to new drugs. A research breakthrough would herald a cure for the MRSA threat.
hypothesis: MRSA-related deaths are now more common.
