To accommodate the increase in cases, oral fluid and serum testing for mumps at PHE Colindale will be for IgM testing alone, with cessation of IgG and PCR testing. Testing will increase from twice per week to daily testing. IgM will identify primary mumps infections but some cases of mumps reinfection may be missed.

Rabies risks for travellers

PHE has published a new leaflet on the risk of rabies, for travellers who are visiting countries where the virus is known - or thought to - occur (particularly Asia, Africa and parts of Central and South America).

It is intended for use by travellers, as well as health professionals who are advising them [1].

The leaflet explains the activities that could require a pre-travel course of vaccination, as well as the general precautions to take when visiting rabies-endemic destinations.

It explains:

  • what to do before travelling
  • what to do if bitten, scratched or licked by an animal
  • rabies post-exposure treatment

For health professionals, the leaflet advises on dealing with patients who are presenting as having had a bite, scratch or lick from an animal while visiting those areas.
