The 2024 influenza season commenced in week 17 (beginning April 22, 2024), as indicated by the breach of the seasonal threshold by the influenza detection rate (3-week moving average) from the NICD inpatient pneumonia sentinel surveillance in public hospitals. This rate remained above the threshold for two consecutive weeks.

As of May 9, 2024, within the pneumonia surveillance program, the predominant subtype and lineage detected were influenza A(H1N1)pdm09 (29/52, 55.8%) followed by influenza B/Victoria (7/52, 13.5%) and (H3N2) (2/52, 3.8%). Among the 52 samples testing positive for 1 sample (1.9%) had an inconclusive subtyping result, while 7 samples (13.5%) were awaiting  subtyping results. Similarly, 1 sample (1.9%) had an inconclusive influenza B lineage result, and 3 samples (5.8%) were pending   lineage results. Additionally, 2 samples (3.8%) tested positive for both A(H1N1)pdm09 and  B/Victoria.

Influenza A(H3N2), A(H1N1)pdm09, and B are among the common seasonal strains affecting humans. While most individuals with experience mild illness, typically resolving within 3-7 days, severe cases can occur, leading to hospitalization or even death. This risk is especially heightened among certain groups susceptible to severe  illness or complications.

High-risk populations include pregnant women, individuals with HIV, those with chronic conditions like diabetes, lung disease, tuberculosis, heart disease, renal disease, and obesity, as well as older adults (aged 65 and above) and children under 2 years old. It’s crucial to encourage members of these groups to seek medical attention promptly if they exhibit symptoms of Early intervention can help mitigate the risk of severe outcomes associated with the virus.

 vaccination is highly recommended as a preventive measure against infection and severe illness. Ideally, individuals should receive the vaccine before the onset of the season, as it takes approximately two weeks for the body to develop antibodies after vaccination. However, it’s essential to emphasize that it’s never too late to get vaccinated.

People at risk of severe illness from  should prioritize getting vaccinated. They can access the vaccine through public health clinics, general practitioners, or pharmacies. Annual vaccination is necessary because the virus undergoes constant changes, and immunity conferred by the vaccine diminishes over time.

Getting vaccinated not only reduces the likelihood of contracting  but also minimizes visits to healthcare facilities, decreases absenteeism from work or school due to influenza-related illness, and helps prevent influenza-related hospitalizations.
