Rabat – Moroccan physician and scientific researcher Tayeb Hamdi has responded to growing public concerns over the spread of the H3N2 influenza strain, commonly referred to as the “super flu.”
These concerns follow a noticeable surge in flu cases amid cold weather. Hamdi said the virus has changed compared to previous years, which is contributing to its faster spread.
He explained that newly developed mutations have partially allowed the strain to evade existing immunity against influenza viruses. “Intense transmission has been observed among adolescents, young adults, and adults, followed by children and the rest of the population,” he said.
According to Hamdi, early influenza seasons were first recorded in Japan, then in the United States, Canada, Europe, and other regions. “This rapid spread of the so-called ‘super flu’ worsens the severity of the H3N2 strain, which is already known to be more aggressive than H1N1,” the Justice and Development Party quoted the physician as saying.
Hamdi also acknowledged an acceleration in cases with flu-like symptoms in Morocco since mid-November. While official figures from the Ministry of Health have yet to confirm the data, he noted that the severity of infections has increased in recent days.
Symptoms of the new “super flu” remain similar to seasonal influenza, including higher fever, chills, headache, joint and muscle pain, as well as a dry cough.
Hamdi emphasized that vaccination against seasonal influenza remains the most effective way to prevent the disease.
He advised people showing symptoms to stay at home and limit contact with others, especially those at higher risk.
He also urged potential influenza carriers to wash their hands regularly and ventilate indoor spaces. “Do not send children who show symptoms to school,” he said.
On December 12, the Pan American Health Organization acknowledged an increased circulation of influenza A or H3N2 in several regions of the world.
In its briefing, it urged the international community to strengthen surveillance and promote vaccination, particularly among the elderly and people with risk factors.
“PAHO also urges countries to ensure timely clinical management of cases and prepare health services for the possibility of early, or more intense, respiratory disease activity,” he said.
The briefing shows a rapid spread in Europe and other countries across the world, including in Asia.
“Health authorities in those countries have not reported significant changes in clinical severity; however, seasons dominated by the A( H3N2) subtype have historically been associated with greater impact among older adults,” PAHO said.
