Mumps is a viral infection that commonly affects school children before the introduction of the MMR (measles, mumps, and rubella) vaccine in the UK in 1998.
Mumps is a contagious condition, and a person is contagious a few days before symptoms appear and is still contagious a few days after symptoms appear, too.
This condition spreads when someone breathes in infected droplets of saliva from another person’s cough. If you are infected and cough, you increase the chances of someone else getting it too.
So a school, college, or university is a perfect breeding ground for the virus because there are lots of potential carriers.
So if an infected person touched their nose or mouth and touched an object such as a door handle or a work surface shortly afterwards, the virus could be transferred to a new host. Or if you are sharing cups or cutlery with an infected person, you could potentially get it too.
People who are infected with mumps can also pass the virus on, even if they show no apparent symptoms.
