The 'weak and ill-defined' standards of care imposed by the Registered Homes Act of 1984 have meant that quality of care in nursing homes is monitored unevenly or not at all, says Yumiko Arai.

The first indication of influenza activity in the Netherlands in the 1998/'99 season was the isolation of an influenza B virus in week 47 of 1998. In subsequent weeks influenza activity slowly increased, reaching a peak in week 6 of 1999. After a gradual decline for three weeks a second peak was reached in week 8 of 1999. The first wave of influenza activity was primarily caused by influenza B viruses, whereas during the second wave predominantly influenza A viruses of the A/H3N2 subtype were isolated. The antigenic properties of the influenza A viruses resembled those of the viruses isolated in the previous season and the vaccine strain A/Sydney/5/97. The influenza B viruses did not completely match with B/Harbin/7/94 which is most commonly used for vaccine production. The vaccine, however, did provide good protection against the epidemic strains of influenza. This season influenza A/H1N1 viruses did not play a significant part and only a small number of viruses of this subtype were isolated at the end of the season. For the influenza season 1999/2000 it is recommended by the World Health Organization that the vaccines contain the following (or similar) virus strains: A/Sydney/5/97 (H3N2), A/Beijing/262/95 (H1N1) and B/Beijing/184/93.
