The H3N2 virus, which is rapidly spreading in the Northern Hemisphere, has caused an outbreak in Japan and Australia, while the flu season in the UK has started earlier than expected. The virus, which has mutated multiple times, reduces the effectiveness of existing vaccines and poses a serious risk, especially to children and the elderly.
The new "H3N2" virus, which emerged in the Northern Hemisphere, has quickly increased its impact in many countries.
SCHOOLS CLOSED, SITUATION ALARMING
Japan declared an epidemic nationwide and decided to temporarily close schools due to the rapidly increasing number of cases. In Australia, the situation has reached alarming levels; health authorities are reporting record levels of patient visits.
FLU VACCINES PROVIDING INSUFFICIENT PROTECTION
In Europe, both the increase in cases and the mutations of the virus are causing concern. Health authorities announced that H3N2 underwent 7 different mutations during the summer months and that the current flu vaccines do not provide sufficient protection against this new variant. In the UK, the flu season has started earlier than expected, and especially those in high-risk groups have been warned about potential fatalities.
RISK INCREASED FOR ELDERLY AND CHILDREN
The new form of H3N2, which presents with classic flu symptoms such as fever, cough, and runny nose, is particularly severe in children and the elderly. Doctors state that the mutations have reduced the immune system's ability to recognize the virus, resulting in a longer and more difficult infection process.
BE AWARE OF SHORTNESS OF BREATH AND FLUID LOSS
Experts point out that one of the reasons for a harsher flu season this year is significant changes in the virus compared to last year. Complications such as shortness of breath and severe fluid loss, seen after high fever during the flu wave in 2017, are also emerging this year and increasing hospital admissions.
SUDDEN WEATHER CHANGES ACCELERATE SPREAD
Dr. Giuseppe Aragona, speaking to The Independent, indicated that children and the elderly, who experienced fewer infections in previous years, are more vulnerable this season. It is also noted that transitions from cold weather to closed and warm environments accelerate the spread of the virus.
Scientists evaluate that the 7 new mutations observed during the summer months are related to global warming. The weather being cold enough to weaken immunity but not low enough to incapacitate the viruses creates an environment conducive to increased mutations.
CONCERN OVER HOSPITAL OVERCROWDING
Dr. Aragona emphasized that those with chronic illnesses and elderly individuals are at higher risk, stating that the increase in cases could put pressure on health systems. However, he noted that there is no need for panic, emphasizing that vaccination, early diagnosis, and healthy nutrition play a critical role in protection.
