A lethal “flesh-eating” micro organism is spreading at a report charge in Japan, with the capital Tokyo a hotspot.

So far this yr, the nation has reported 977 circumstances of streptococcal poisonous shock syndrome (STSS) – already exceeding an all time excessive of 941 infections detected in 2023.

The situation is brought on by an uncommon manifestation of the strep A micro organism.

The pathogen itself is widespread; between 5 and 20 per cent of wholesome adults have latent, symptom-free infections.

But it will possibly progress into a variety of ailments, from tonsillitis and impetigo to scarlet fever and pneumonia. In some extreme circumstances, strep A micro organism can change into invasive – seeping from cuts and wounds deep into gentle tissue and muscle, the place it triggers necrotising fasciitis, a “flesh-eating disease”.

It is that this situation that’s at the moment spreading at report charges in Japan, in accordance with information from the county’s National Institute of Infectious Diseases this week.

Symptoms start with a fever or muscle aches, adopted by low blood strain – organ failure and septic shock can observe inside 48 hours, and it may be lethal with out speedy remedy with antibiotics.

In Japan, the capital Tokyo has been most affected by the report surge, with 145 circumstances within the first six months of 2024. The majority of circumstances are in adults over 30, whereas the demise charge has hovered at round 30 per cent, in accordance with the newspaper Asahi Shimbun.

“It is not unusual to see ‘surges’ in cases, [and] we have had such surges in the UK in the past,” mentioned Prof Jon Cohen, Emeritus Professor of Infectious Diseases at Brighton and Sussex Medical School. “Occasionally the explanation is a new strain of bacteria, but otherwise there is often not a really good explanation other than local contagion.”

Pandemic rebound

In December 2022, the World Health Organization issued an alert after a spike of invasive strep A infections, together with scarlet fever, in Britain, France, Ireland, the Netherlands and Sweden – although the vast majority of these circumstances affected youngsters.

“In England the number of group A strep cases (sore throats, scarlet fever and the rarer invasive infections) plummeted during the Covid-19 pandemic… [and] younger children did not encounter group A strep as they might normally do,” mentioned Prof Shiranee Sriskandan, a professor of infectious ailments at Imperial College London.

“There was therefore a bigger pool of children susceptible to group A strep when social mixing restrictions were lifted, and this probably led to the increase that we saw in 2022.”

She added that comparable tendencies could now be enjoying out throughout Japan.

“It is very likely that events in Japan are a delayed rebound in cases following relaxation of social mixing restrictions during the Covid-19 pandemic, similar to what was seen in England and elsewhere.

“Restrictions were lifted at different times across the world, leading to a phased upsurge in Strep A cases. [This could explain] why Japan is seeing an increase this year. It may be that differences in seasonal timing have led to the effect on children being less evident.”
