A new strain of the corona virus was announced by the British government in mid-December 2020, followed by a new strain in South Africa.
In less than a month, a third new strain of the corona virus has been discovered in Japan.
According to the Japanese Ministry of Health, this new strain of corona virus was discovered in people who came from Brazil, but it is different from strains found in the United Kingdom and South Africa.
According to a statement from the Ministry of Health, a new strain of corona was discovered in Japan at airport tests on a man over 40 years of age, a woman over 30 years of age and two young men (a boy and a girl).
Japan is now working with other countries, the World Health Organization and medical experts to analyze the new strain of the virus, and it is unclear whether the available vaccines will be effective against it.
The man, who was diagnosed with the new virus, showed no symptoms when he arrived in Japan but was later hospitalized with difficulty breathing.
The victim complained of a headache, while a young boy had a fever and the young girl showed no symptoms.
Japan has already diagnosed 30 new cases discovered in the UK and South Africa, which experts say could spread more rapidly.
The new strain discovered in Japan is called B1.1.248 and contains at least 12 mutations.
One of these mutations is also found in species discovered in the United Kingdom and South Africa, raising fears that the species discovered in Japan may be more contagious.
However, Takaji Wakita, head of Japan's National Institute of Infectious Diseases, said there was no evidence at the time that the new strain was more contagious.
Detailed research is being conducted by Japanese scientists to determine how contagious it is and whether the vaccines will work.
Japanese experts identified the type after a detailed examination of the four passengers.
Japanese experts made the new type on January 6, while the passengers arrived from Brazil on January 2.
In Japan, too, there has been a record increase in the number of cases of code 19 in recent weeks, and an emergency has been declared in the capital, Tokyo.
Japan has also banned people from certain countries from entering its territory, while screening people coming from abroad to prevent the spread of new species that are considered more contagious.
