Swab used in measles frequency studies, London, England, 1996
Swabs are used to obtain a sample of saliva. Once obtained, the swab would be sent to the Communicable Diseases Surveillance Centre, part of the Public Health Laboratory Service (PHLS), to be tested for measles. Measles is easily spread by droplets from coughs and sneezes and from the saliva of infected individuals. As a communicable disease, the number of people who contract it must be reported. The PHLS was founded under the National Health Act of 1946 to provide laboratory services throughout the United Kingdom.
