It's certain that there will be an influenza season, unlike in 2020 and 2021 when COVID-19 restrictions significantly impacted influenza circulation. In 2022, influenza made a strong comeback and is expected to circulate widely once again in 2023.
The exact start of the season remains uncertain. Before the pandemic,
cases typically rose in May, reached a peak in August, and then declined in
October. In 2022, the resurgence of influenza was linked to the reopening
of international borders. In 2023, seasonal flu activity is anticipated to
persist, making it crucial to emphasize the importance of flu vaccination.
Annual vaccination is the most effective way to prevent influenza and its
complications, and it is recommended for all individuals aged six months
and older.
Update March 2023
In the first two months of 2023, there were 8,474 laboratory-confirmed influenza cases,
compared to only 79 cases in the same period of 2022. This increase can be attributed to
the easing of COVID-19 restrictions, which had kept influenza cases artificially low in
previous years.
Current flu rates are similar to those seen in pre-COVID years, and the start, length, and
severity of the 2023 flu season remain unpredictable. Community immunity is expected
to be lower due to fewer infections during COVID restrictions and reduced influenza
vaccine uptake in recent years
It is essential to prioritize vaccination, especially considering the early flu season
experienced in 2022. With only about 40% of eligible individuals vaccinated in 2022, it is
crucial to prepare for workplace vaccinations now. By doing so, businesses can protect
the health of their employees during the upcoming flu season.
