Health experts from the United States and the United Kingdom have raised alarms about an unprecedented wave of influenza, referred to by the UK Health Services Authority as "resistant influenza." They are urging citizens to get vaccinated to mitigate potential symptoms.
Significant Increase in Cases
While respiratory illnesses typically rise during winter months, New York City reported nearly 1,400 influenza cases in the first week of December, marking an increase of approximately 460% compared to the same period last year, according to The Hill.
The circulating strain is H3N2 – subvariant K of Influenza A, known to be particularly severe, especially among children and the elderly.
Symptoms of Resistant Influenza
The Gulf Center for Disease Prevention and Control has highlighted the primary symptoms associated with this strain:
Elevated temperature
General fatigue and tiredness
Body aches and a general feeling of malaise
Although most patients begin to recover within 5 to 7 days, some symptoms may persist for up to two weeks.
Vaccination and Preventive Measures
The World Health Organization has confirmed that current vaccines provide effective protection against severe symptoms of this virus, making seasonal vaccination a key defense strategy.
Additionally, health experts stress the importance of basic preventive measures such as:
Ensuring good ventilation in indoor spaces
Frequent handwashing
Seeking early medical intervention as soon as symptoms appear, particularly for pregnant women and the elderly, to reduce the risk of severe complications.
