## Key points
- South Africa's "flu season" officially kicked off on 22 April, with the National Institute for Communicable Diseases reporting no signs that this year's influenza strain is any nastier than its predecessors, but brace yourselves for the inevitable surge in hospital admissions and unfortunate fatalities, as 20-40% of the population is expected to catch the bug annually - so wash those hands, cover those coughs, and maybe invest in some hand sanitiser.
- South Africa's flu season began on 22 April, with no indications of it being worse than previous years, according to the National Institute for Communicable Diseases.
- Dr Sibongile Walaza from NICD stated that 20-40% of South Africa's population is infected with influenza annually, with hospital admissions and deaths expected to rise during the flu season.
- The flu season is determined by a three-week moving average, with 78 positive flu cases found in 1,798 samples taken from surveillance programmes, mostly in Gauteng.
- NICD's influenza alert confirmed that A(H1N1)pdm09 is the most common strain, spreading through infected droplets and causing symptoms like fever, cough, and body aches.

South Africa is in “flu season”, which began on 22 April. The National Institute for Communicable Diseases said there were no indications that this year’s flu was worse than before.

Dr Sibongile Walaza, the head of epidemiology at the National Institute for Communicable Diseases (NICD) Centre for Respiratory Diseases and Meningitis, said 20-40% of South Africa’s population is infected with influenza every year.

“It is still too early to tell how severe the current influenza season will be. However, from the surveillance programme data we have at the moment, there are no indications that the current influenza season is more severe than previous ones.”

She said hospital admissions (and deaths) were expected to increase during the flu season. Previous data estimates are that on an annual basis in South Africa, “an estimated 56,000 individuals are hospitalised with influenza”, she added.

Flu season starts when the three-week moving average (adding all the cases over three weeks and dividing by 21) remains above a certain number for two consecutive weeks. These cases are taken from in-patient programmes monitored by the NICD.

According to the latest surveillance report published by the NICD, 1,798 samples were taken from patients in surveillance programmes from the start of 2024. Of these, 78 tested positive for one of the flu viruses. Most positive cases were found in Gauteng.

An [influenza alert](https://www.nicd.ac.za/wp-content/uploads/2024/05/Flu-alert-2024-final_20240510.pdf) issued by the NICD on 9 May confirmed that influenza A(H3N2), A(H1N1)pdm09 (referred to as swine flu) and influenza B were common seasonal influenza strains in humans. So far, most samples taken in surveillance programmes tested positive for A(H1N1)pdmo9.

The flu virus spreads from person to person through infected droplets, either through inhalation or by touching a contaminated surface and then touching your mouth, nose or eyes.

The most common symptoms are sudden onset of fever, muscle pains and body aches, a dry cough, a sore throat, a runny nose, or feeling tired or unwell and headaches.

Complications like pneumonia can result in hospitalisation. **DM**
