Young adults in their 20s could be susceptible to inflammatory Kawasaki-like syndrome believed to be caused by coronavirus
- Kawasaki-like condition is believed to be caused by infection with SARS-CoV-2
- It primarily affects children and, although rare, can be lethal in extreme cases
- Reports claim some patients are being treated for the condition are in their 20s
- Believed the condition emerged several weeks after initial infection with virus
- Body's delayed immune response goes haywire and this itself causes the Kawasaki-like symptoms, which can be fatal in the most extreme cases
Doctors in America believe the inflammatory Kawasaki-like condition caused by coronavirus could be affecting adults in their early 20s.
The mysterious condition is affecting children and has been shown to be linked to previous infection with the SARS-CoV-2 coronavirus, which also causes COVID-19.
Reports in the Washington Post claim several patients in their 20s are being treated for the condition in San Diego and New York.

The eight-month-old Alexander had rashes and a high temperature, both symptoms of the mysterious Kawasaki-like disease. Little is known about the condition at the moment but it is believed to be rare
It appears the patients were been infected with the coronavirus but developed antibodies, indicating they contracted the infection several weeks ago.
It is believed the hyper-inflammatory condition, which resembles Kawasaki disease, is a delayed immune response to the infection.
It is known as PIMS-TS (paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2) in Europe and MIS-C (multisystem inflammatory syndrome in children) in the US.
According to US-based doctors, adult patients expressing symptoms of the new condition have more severe symptoms than children, which can affect the lungs and heart.
Current treatments seem to be effective and involve steroids, anticoagulants, immunoglobulin and, occasionally, ventilation and admission to intensive care.

Children with the illness are usually taken to hospital with a high fever that has lasted a number of days and severe abdominal pain. The most seriously ill may develop sepsis-like symptoms such as rapid breathing and poor blood circulation
Younger children have symptoms more closely related to Kawasaki disease, such as inflammation of the blood vessels and rashes.
However, the emerging condition appears to be able to infect a range of people, from infants to those who have lived for a quarter of a century.
Some diseases are known to affect children but not adults, and vice versa. The reason for this remains a scientific enigma, lacking a viable explanation.
Biology does not suddenly change at 18 years old, and the impact of ageing on physiology is a progressive shift which transcends the label of adult and child.
The first wave of coronavirus patients had COVID-19 and this disease targets the respiratory system, particularly affecting people with underlying health conditions.
However, the new condition seems to mostly affect previously healthy individuals who develop a fever, nausea and vomit.
Little is known about the condition at the moment but it is believed to be rare.
However, there have been deaths from the disease. This week, a 14-year-old boy in London died from the disease. There have been reports of four deaths in the US.
The mother of an eight-month-old baby who died of the rare illness urged parents to be 'vigilant' to the symptoms, and called for more research into the disease.
Alexander Parsons, from Plymouth, died at Bristol Children's Hospital last month after being diagnosed with Kawasaki disease, his family said.
