Japanese flu – or Yamagata – is a particular strain of influenza B.

The bug is said to be less serious than Aussie flu – or H3N2 which is also sweeping the country – but more contagious.

The flu, which originated in Yamagata, Japan, has already made its presence known in Ireland and Greater Manchester, and doctors are urging parents to have their kids vaccinated.

Children are especially susceptible to this type of flu as they are “super spreaders” – meaning they transfer the virus to a greater number of people than the average infected host.

They are also deemed by experts to be “super shredders” – meaning that their immune systems can’t distinguish between what makes them ill and what will kill them – causing their body to excrete more of the virus.

The bug has already overtaken Aussie flu in Ireland – and reportedly accounts for around 60-70% of confirmed flu cases. 

What are the symptoms of Yamagata?

Symptoms of Yamagata flu are similar to those of an ordinary flu, but can be more severe.

Those who have Yamagata may experience extreme fatigue, and most people will experience headaches and muscle soreness.

Nasal congestion, runny noses and sore throats are also common.

Some may experience a dry cough as well. Other symptoms include fever, vomiting and/or diarrhoea.

According to the Medical University of South Carolina symptoms of Yamagata are more severe and sudden than other respiratory diseases.

Symptoms will generally start to disappear within a week. If symptoms persist, or worsen, you should contact your GP.
