A mysterious new related to coronavirus The disease has made headlines in recent weeks, after several cases have been seen in children around the world.
The disease is being described as an "inflammatory syndrome", similar to Kawasaki disease and toxic shock syndrome.
Toxic shock syndrome (TSS) is often associated with tampon use in young women, but it can actually affect anyone of any age – including children.
The condition is rare, but life-threatening, and is caused by bacteria that enter the body and release harmful toxins.
The NHS explained: “TSS gets worse very quickly and can be fatal if not treated immediately. But if diagnosed and treated early, most people recover completely. "
According to the NHS, TSS has nine main symptoms:
- A high temperature
- Flu-like symptoms, such as headache, feeling cold, tiredness or exhaustion, aching body, sore throat and cough
- Feeling and being sick
- A generalized rash like sunburn
- Lips, tongue and white part of the eyes turning bright red
- Dizziness or fainting
- Difficulty breathing
If you notice these symptoms in your child, it is important to seek medical help as soon as possible.
The NHS added: “Toxic shock syndrome (TSS) is a medical emergency.
"While these symptoms may be due to a different condition, it is important to contact your family doctor, a local out-of-hours service or NHS 111 as soon as possible, if you have a combination of these symptoms."
Doctors have already reported cases of the mysterious disease in the UK, USA, France, Italy, Spain and Switzerland.
The first reports were in the United Kingdom, where there are believed to be at least 12 cases.
Meanwhile, French Health Minister Olivier Veran revealed earlier this month that the disease was seen in "about 15 children of all ages".
Speaking to Franceinfo, Veran also confirmed that cases have been reported in Spain, Italy and Switzerland, listing fever, digestive problems and vascular inflammation as the main symptoms.
