UK mumps epidemic threat
Cases of mumps in England and Wales increased dramatically last year, the Health
Protection Agency has announced. In 2004 8,104 cases of
mumps were confirmed, compared with a total of 3,907 cases in the previous
five years.
Most cases occurred in young adults born before 1988, who would not have
been routinely scheduled for the measles, mumps and rubella vaccination.
Only 2.4 per cent of confirmed cases in 2004 occurred in children who
would have routinely been offered two doses of the vaccine. The scientists
suggest that school leavers should have their vaccinations reviewed to
ensure that they have received two MMR doses (BMJ 2005;330:1119). A second
paper reveals that there were almost 5,000 notifications of mumps in
January alone, mainly among 19–23 year olds, and that there is
now a threat of outbreaks among under-immunised children, since uptake
of the MMR vaccine fell (ibid, p1132). |
