During the last week of December 2024, Japan saw its largest flu outbreak in 25 years, with over 317,800 people reported sick between December 23 and 29. This figure is a significant rise compared to the 104,600 cases reported the same week in 2023, making it the highest weekly number since records began in 1999.
Flu cases are common in winter, not only in Japan but globally. Other countries like France and Britain also reported large increases in flu cases this year. In Australia, last year saw more than 350,000 confirmed flu cases, a sharp rise from the previous high of 313,600 cases in 2019.
Why the Surge in Cases?
Experts believe that the lifting of COVID-19 restrictions may have played a role in this flu spike. Due to lockdowns, people were less exposed to the flu virus in recent years, potentially lowering their immunity. This might explain why there is a high number of flu cases now.
What’s Being Done?
Japan’s health ministry is closely monitoring the flu outbreak, using reports from over 5,000 clinics. They’re advising the public to get vaccinated, wash their hands frequently, and wear masks, particularly during the busy holiday season when many people gather.
Global Flu Trends
Flu activity is rising in many parts of the world, and similar factors could be contributing, such as reduced exposure to the virus during COVID-19 lockdowns. Countries are keeping a close watch on flu trends and preparing for a potentially tough flu season.
What You Can Do
– Get Vaccinated: The flu shot can reduce the severity of illness if you catch the flu.
– Practice Good Hygiene: Wash your hands often and avoid touching your face.
– Wear Masks: In crowded places, wearing a mask can help prevent the spread of the virus.
– Stay Home If Sick: If you’re feeling unwell, staying home will help avoid spreading the flu.
This flu outbreak highlights the importance of staying vigilant about health, especially after periods when fewer people were exposed to common viruses due to social distancing measures.
