Brief description A newly discovered paramyxovirus, human metapneumovirus (hMPV), shows clinical and virological charcteristics very similar to those of human respiratory syncytial virus (hRSV). Human RSV is the major cause of acute lower respiratory illness in infants and accounts for more than 1 million deaths world wide annually. Most infants are infected in their first year of life, and re-infection is common. Genetic variation of the virus is thought to play a critical role in its ability to escape the immune response and establish multiple sequential infections in the same host. Currently, we have no knowledge of the extent that hMPV exists in the Australian population, nor do we know if hMPV is a significant respiratory pathogen in paediatric patients. This research aims to determine the importance of hMPV as a respiratory agent, and will establish the rate, age of exposure, and incidence of hMPV infection in Australian children. In addition, we will identify the hMPV strains (genotypes) that infect local children, and the difference, if any, between these and virus strains detected in children from other community groups, and from overseas. Such data is invaluable in devising a future vaccine strategy for hMPV, and the study of the genetic variability among Australian strains will have profound implications for public health. This research project is a preliminary study into the clinical and virological significance of hMPV, in children, and will form a basis for future research projects. Once this preliminary data is obtained, further studies are possible to determine the cellular immune response to hMPV infection and its role in long-term protection. Also,it is likely that hMPV, like hRSV, may prove to be an agent associated with long-term decreased pulmonary function and airflow limitation perhaps developing to asthma.
