Five symptoms of 'highly contagious' whooping cough sweeping across UK in outbreak

Cases of a 'highly contagious' bacterial bug have increased 250% in the UK within a year, and it's vital to get children and babies vaccinated against whooping cough

A whooping cough outbreak has hit the UK, with 716 reported cases between July and November.

The UK's Health Security Agency (UKHSA) warned the public that the rise in cases were expected, but it was still crucial to protect children and get them vaccinated. Coronavirus lockdowns and social distancing had significantly dampened the spread of the infection, which meant a rise in cases was almost inevitable.

Whooping cough is a highly contagious bacterial infection that affects the lungs and breathing tubes. UKHSA's Dr Gayatri Amirthalingam said: "As expected, we are now seeing cases of whooping cough increase again, so it's vital pregnant women ensure they get vaccinated to protect their baby."

Whooping cough - which is also known as pertussis - could be mistaken for a cold in its early stages, according to the NHS. A runny nose and sore throat could ultimately be signs of the infection. But, there are five key symptoms of whooping cough to look out for, and they usually develop after about a week.

Five key signs of whooping cough

• Coughing bouts lasting for a few minutes and are worse at night
• Coughs that make a "whoop" sound – a gasp for breath between coughs
• Difficulty breathing after coughs, which could lead to turning blue or grey in young infants
• Bringing up a thick mucus, which can lead to vomiting
• Turning very red in the face

The characteristic whooping cough could last for several weeks or months, warned the NHS. If you have a baby that's under six months old who's started to develop whooping cough symptoms, you should speak to a doctor as soon as possible. Seeing as the infection spreads so easily, it's best to avoid physically going into your GP surgery. Instead, phone ahead of your arrival; they might suggest you have a phone consultation instead.

You should, however, go straight to A&E if you or your child develop blue or grey lips or skin, or if you're struggling to breathe. If the infection is diagnosed within the first three weeks, it can usually be treated with antibiotics. It's vital that you finish the course of antibiotics, even if you feel better.
