Brief Summary:
This study will determine the frequency of Staphylococcus aureus carriage in household contacts of individuals with clinical infection due to this pathogen It will also assess the frequency of transmission events over the following three months Finally it will aim to identify predisposing characteristics both on a demographicsocial level as well virulence characteristics of the identified strains
Detailed Description:
This is a prospective cohort study based at Anuradhapura Teaching Hospital Sri Lanka Potential index study participants will have clinical infection caused by Staphylococcus aureus and will be identified from hospital microbiology laboratory records within 48 hours of admission With consent the investigators will approach up to 4 household members for participation in the carriage study With their consent household members will have swabs collected on 2 occasions 3 months apart All hospitalised patients will receive standard-of-care treatment in accordance with local practice and national guidance Clinical demographic and sociallifestyle data will be collected from index patients and households by scheduled interview performed by local investigators Bacterial isolates from the initial index patient infection and those identified through household member screening will be assessed for antimicrobial susceptibility virulence factor repertoire and analysed by whole genome sequencing While infection with the cc5 MRSA clone has been described in several hospital and hospital-associated settings in South Asia a major unresolved issue is whether transmission and circulation of this clone is occurring in community settings In this study the investigators will investigate and characterise the household circulation of Staphylococcus aureus strains exploring differences in bacterial virulence characteristics and host susceptibility factors associated with increased risk of carriage Understanding these factors and estimating the burden of disease which may be occurring in the community setting will allow more accurate assessment of the risk posed by cc5 PVL-MRSA to similar Low and Middle Income Countries LMIC settings and signal potential routes to mitigation through treatment optimisation and disease prevention including infection control or vaccination
