Freezing temperatures over the past few weeks have exacerbated conditions for potential influenza infections, with young children and senior citizens at the highest risk.
The rapid rise of flu patients across the country is expected to prompt health authorities to issue a nationwide influenza warning soon. Korea is expected to boast the highest rate of flu vaccinations in recent years with about 15 million people getting vaccinated this winter.
However, annual flu shots don't guarantee protection from every viral strain. Strict personal hygiene can also prevent the spread of the influenza virus, while wearing masks outside and frequently washing your hands with soap are also highly recommended.
