Amid the evil of pandemics, the worst flu outbreak in more than ten years has caused extremely high infection rates

The number of flu-related hospitalizations doubled during Thanksgiving week in the United States, and was the highest recorded since the 2010-2011 season, according to the CDC.

But about 4 in 10 Americans say they don't plan to get the flu vaccine this season, due to concerns about vaccines that don't work well or have side effects.

Public health experts say that wearing a mask and other precautions used during the corona pandemic have kept the flu at bay over the past two years and disrupted its seasonal spread, but the return to normal pre-pandemic life has left us more vulnerable to infection.

Experts warn that they still do not know much about seasonal viruses and continue to deal with questions such as how much Corona has weakened people's immunity.

"We cannot let our guard down, we have to take the precautions we need to prevent the spread of these viruses, such as washing our hands, wearing masks in crowded indoor places, and staying at home if we are sick,"said American surgeon Vivek Murthy.

Amid the high rates of fears for pregnant women from contracting the flu, the infectious diseases research and Policy Center at the University of Minnesota pointed out that the uptake of the flu vaccine for pregnant women is 12.1 percentage points lower than in 2021 and 21.7 percentage points lower than in 2020.

In summary, the threat of the emerging coronavirus may be more manageable thanks to vaccines, antiviral drugs and tests, but the experience of the pandemic may have made us more vulnerable to waves of other seasonal diseases that complicate the return to normal.
