Parents must be on the look out for a potentially deadly but also common bug increasing among kids this winter, experts have warned.
Respiratory syncytial virus (RSV) is a chest infection that affects babies and children under the age of two.
The bug usually only causes mild cold-like symptoms in children.
But in some cases, the virus can be deadly and can lead to pneumonia, bronchiolitis and asthma, in both children and adults who survive it, the Centre for Disease Control (CDC), states.
Cases of the bug, which infects the lungs, have surged recently, especially among under-fives, the most recent data from the UK Health Security Agency (UKHSA) states.
The number of positive tests has increased by 9.2 per cent in the week ending November 13 and experts have warned people to stay away from little ones if they are feeling unwell.
The early symptoms of the illness are similar to a cold and include:
A runny or blocked nose,
A high temperature
Breathing more quickly
Finding it difficult to eat or feed
Guidance states that symptoms are usually worst between days three and five of the bug, with the cough getting better in three weeks.
If you are worried about any of your child’s symptoms then you should contact your GP.
