Influenza is often regarded as an illness of the elderly portion of the population because most of the excess mortality associated with influenza epidemics occurs in that age group. However, evidence derived from a large number of clinical studies carried out in different countries and various settings has clearly demonstrated that the burden of influenza(More)
The sensitivity of the Enhanced Tuberculosis Surveillance (ETS) scheme for monitoring tuberculosis in children is unknown. We used the British Paediatric Surveillance Unit (BPSU) reporting scheme to conduct a prospective observational study of tuberculosis in children aged <16 yrs in the UK. Reported cases were then matched with records from the ETS(More)

AIMS To describe the clinical features, diagnosis and management of children with tuberculosis in the United Kingdom and Republic of Ireland. METHODS Cases of culture-confirmed and clinically diagnosed tuberculosis were reported to the British Paediatric Surveillance Unit from December 2003 to January 2005. RESULTS 385 eligible cases were reported.(More)
We conducted a prospective, nested study using nucleotide sequencing to examine influenza positive respiratory samples in families for genetic homology in the hemagglutinin and neuraminidase genes. Influenza A H3N2 viruses from 3 families had identical, family specific, HA1 nucleotide sequences. Sequences among these families were genetically heterogeneous.(More)
The United Kingdom has recently changed its BCG vaccination policy in response to the changing epidemiology of tuberculosis (TB) in children. One of the changes has been the abandonment of the long standing school's BCG programme because of the low risk of TB in that population. The other change has been the targeting of those infants and children at(More)
Influenza is a disease of global public health significance. Traditionally the emphasis has been on adult disease because of the impact of influenza related mortality in the elderly and other high risk groups. However, it is becoming increasingly better recognised that young children suffer considerable morbidity from influenza. There are also potential(More)
Every winter there are sharp rises in medical visits, hospitalizations and deaths from acute respiratory illness worldwide. Influenza is an important cause of these and is the only common viral respiratory pathogen with licensed vaccines available that are safe and effective in preventing disease. Over 50 countries have national vaccination programs(More)
