Whooping cough (pertussis) is a bacterial infection of the lungs and breathing tubes. It spreads very easily and can sometimes cause serious problems. It's important for babies and children to get vaccinated against it.

The first signs of whooping cough are similar to a cold, such as a runny nose and sore throat (a high temperature is uncommon).

After about a week, you or your child:

• will get coughing bouts that last for a few minutes and are worse at night
• may make a "whoop" sound – a gasp for breath between coughs (young babies and some adults may not "whoop")
• may have difficulty breathing after a coughing bout and may turn blue or grey (young infants)
• may bring up a thick mucus, which can make you vomit
• may become very red in the face (more common in adults)

The cough may last for several weeks or months.

Ask for an urgent GP appointment or get help from NHS 111 if:

Babies under 6 months old with whooping cough have an increased chance of having problems such as:

• dehydration
• breathing difficulties
• pneumonia
• seizures (fits)

Whooping cough is less severe in older children and adults but coughing may cause problems including:

• sore ribs
• hernia
• middle ear infections
• pee leaking out when you cough (urinary incontinence)

Call 999 or go to A&E if:

Treatment for whooping cough depends on your age and how long you've had the infection.

Hospital treatment is usually needed if you have severe whooping cough, or your baby is under 6 months old and has whooping cough.

If whooping cough is diagnosed within 3 weeks of the infection, you'll be given antibiotics to help stop it spreading to others. Antibiotics may not reduce symptoms.

If you've had whooping cough for more than 3 weeks, you're no longer contagious and do not need antibiotics.

Important

Keep taking the antibiotics until you've completed the course, even if you feel better. Stopping treatment too soon could lead to the infection coming back.

There are some things you can do to help ease the symptoms of whooping cough.

If you have whooping cough, you're contagious from about 6 days after the start of cold-like symptoms to 3 weeks after the coughing starts.

If you start antibiotics within 3 weeks of starting to cough, it will reduce the time you're contagious for.

Important

Stay off school, work or nursery until 48 hours after starting antibiotics, or 3 weeks after your symptoms started if you've not had antibiotics.

The whooping cough vaccine protects babies and children from getting whooping cough. That's why it's important to have all the routine NHS vaccinations.

The whooping cough vaccine is routinely given as part of the:

• 6-in-1 vaccine – for babies at 8, 12 and 16 weeks
• 4-in-1 pre-school booster – for children aged 3 years 4 months

If you're pregnant you should also have the whooping cough vaccine – ideally between 16 and 32 weeks.
