Deadly MRSA spread by coughs and sneezes

2nd February 2012

A warning has been issued over a new strain of MRSA that has been identified in the UK.

MRSA1

The strain, called USA300, has been described as a flesh-eating form of pneumonia and can be easily passed between healthy people on public transport, passing through skin-to-skin contact.

The form of MRSA was first seen in America but is now being seen in hospitals and in the community in Britain.

Dr Ruth Massey, from the Department of Biology and Biochemistry at the University of Bath, said: “These community-acquired strains seem to be good at affecting healthy people - they seem to be much better than the hospital ones at causing disease. They don't rely on healthcare workers moving them around, which the hospital ones seem to.”

USA 300, which is resistant to treatment by several front-line antibiotics, can cause large boils on the skin and even lead to fatal blood poisoning or a form of pneumonia that can eat away at lung tissue.

In England last year, there were 1,000 cases of PVL-positive community acquired MRSA, of which 200 were USA300 strains.

Dr Massey and her team are working on the strain and have been analysing it to understand it better and avoid it becoming a major issue in the UK.

The new research is published in the Journal of Infectious Diseases.

A spokeswoman for the Health Protection Agency said: “The paper highlights some important observations which helps us understand at the molecular level why hospital strains of MRSA are less virulent than the so-called community MRSA strains.”

Active UVC based technologies when placed in a building's infrastructure will kill any of bacteria & viruses regardless of it's type/variant constantly bathing the occupied space with natural oxidisers that kill airborne and surfaces 24/7. When will the HPA wake up to the widespread use this simple & low cost technology.
