According to the National Institute for Communicable Diseases, South Africa is officially in the grip of its influenza season, and the onset has come sooner than anticipated, marked by several pneumonia cases reported at local hospitals.
The NICD said SA's flu season arrived four weeks earlier than last year, the earliest start since 2010.
The NICD added that while the early start does not necessarily mean a more severe flu season this year, people are urged to opt to take the seasonal flu jab to protect themselves and loved ones.
According to the institute, while the vaccine is most effective when administered before the flu season commences, it is not too late for individuals to get vaccinated.
It said protection begins to develop approximately two weeks after vaccination, emphasising the importance of timely administration. Moreover, annual vaccination is essential, as flu viruses evolve over time, and immunity does not persist beyond a single season.
For most people, flu symptoms are mild and resolve in a few days. But for some, influenza can lead to severe illness, hospitalisation, or even death. Those most at risk include:
- Pregnant women
- People living with HIV
- Individuals with chronic conditions like diabetes, lung disease, heart disease, tuberculosis, kidney disease, or obesity
- Older adults (65 years and older)
- Children younger than two-years-old
The NICD further urged healthcare workers to get vaccinated in order to protect themselves and those patients who could face a higher risk of contracting the virus and experiencing severe complications.
These vaccines are offered free of charge to high-risk individuals, healthcare workers and pregnant women.
Healthcare workers are also encouraged to be vaccinated to protect not only themselves but also patients who may be at a higher risk of experiencing severe influenza complications should they contract the virus.
Tips to prevent spreading the flu
- Wash hands frequently
- Cover coughs and sneezes with your elbow or a tissue
- Avoid close contact with people who are unwell
- Stay home if you are feeling unwell
The NICD warned that if symptoms get worse or do not improve within three to seven days, residents should urgently seek medical attention.
Meanwhile, clinicians are urged to consider influenza when diagnosing patients with respiratory illness this season.
