Leaflets are being circulated to emergency departments, GP surgeries and maternity wards, warning of the signs and symptoms of sepsis.
The UK Sepsis Trust with ambassador Melissa Mead who lost her son to Sepsis in December 2014, are working with NHS England to raise awareness of this "silent killer".
The campaign is aimed at parents of children 0-4 years old and the Trust hopes to try to reduce the 120,000 cases of sepsis in adults and children that occur every year.

“Sepsis is a major killer, claiming over 37,000 lives each year, which is why it is so important for parents to know what action to take when their child is unwell. This campaign will help parents identify when their children are seriously unwell and to encourage them to seek urgent medical attention. We know that acting quickly can save a child’s life.
