Flu season started in March, confirms NICD
CAPE TOWN - The National Institute of Communicable Diseases (NICD) confirmed that flu season started on 24 March with patients being admitted for pneumonia.
The NICD reported that, historically, this year's flu season arrived earlier than past seasons.
Health officials advised the public to wash their hands regularly, cover coughs and sneezes and to avoid contact with people at risk of respiratory illnesses.
Western Cape Health Department COO, Saadiq Kariem, said that transmission of the flu was currently low.
"And so they do monitory of all the flu variants and what they found so far in fact since the 30th of December 2024 to the first of June 2025, of the samples tested, they found that there were 9.5% of cases were influenza but they also do monitoring of other respiratory pathogens and so they found that 16% of those cases were in fact RSV or respiratory syncytial virus and 3.5% of those cases were in fact from SARS CoV2."
Kariem added that regular vaccinations provided a defence against the virus.
"But this is why it's important to vaccinate every year, because the variants change all the time, much like we've obviously people understand how the SARSCoV2 virus has changed all the time."
He detailed the types of influenza variants that had been detected this winter season.
"So the flu virus changes all the time, every season, and most of the cases this far are from influenza A and the subtype is H3N2, but the NICD also picked up influenza A, H1N1 and a small amount of cases have been influenza B."

Doctors reporting a range of flu infections this winter season
CAPE TOWN - The winter season in 2025 has brought with it more than just icy cold and rainy conditions. Doctors are reporting a range of flu infections, which include Respiratory Syncytial Virus, Influenza A, better known as swine flu and Influenza B types. The National Institute for Communicable Diseases (NCID) said there has been an increase in these types of infections this winter season. The institute's Anne von Gottberg explained: 'Most predominantly, it's been H1N1, which is not unexpected, we've had one or two other types, and there's three types that we would be expecting - two Influenza A types and one influenza B type - and at the moment, its exactly as expected.' Gottberg said flu vaccines are assessed each year to make sure they are still a good preventative measure. 'Well, they are slightly different, which is why we need to give the influenza vaccine each year. So, the influenza virus drifts a little. It has small changes in its genome, in its genetic background, and that makes it slightly different each year and that's the reason for reviewing the vaccine and making sure that we have updated influenza virus components in the Influenza vaccine.'

New Covid-19 variant NB.1.8.1 spreading, what to expect in SA
Speaking at the G20 Health Working Group on Tuesday, Health Minister Dr Aaron Motsoaledi said South Africa is well prepared to respond. As the new Covid-19 variant spreads across China, South Africa is closely monitoring the Omicron descendant, NB.1.8.1, as health authorities prepare for its potential arrival. According to the National Institute for Communicable Diseases (NICD), as of Tuesday, 10 June 2025, the NB.1.8.1 variant has not been detected in South Africa. 'Data from the NICD's respiratory illness syndromic surveillance programmes, which operate in selected public and private hospitals and outpatient facilities, show that the number of SARS-CoV-2 infections is currently low,' it said. However, the country is experiencing a rise in influenza (flu) cases due to the onset of the cold season. 'South Africa is well prepared' Speaking at the G20 Health Working Group in Johannesburg on Tuesday, Health Minister Dr Aaron Motsoaledi said South Africa is well prepared to respond. 'I wish to reassure this esteemed gathering that South Africa has robust surveillance systems in place. 'Our NICD manages a comprehensive sentinel surveillance programme that systematically tests for key respiratory viruses, including SARS-CoV-2, influenza, and RSV. Currently, our data show very low SARS-CoV-2 activity,' Motsoaledi explained.

'Crucially, the new variant remains a descendant of the Omicron lineage. Therefore, at this stage, no specific new public health actions are required from the public,' he said. Flu season Motsoaledi said the government continues to promote good hygiene practices, including hand washing, covering coughs, and staying home when feeling unwell. 'These simple measures are effective in reducing the spread of all respiratory illnesses. We will continue to monitor the situation closely through our established networks and will report any significant changes.' During flu season, the NICD reminded the public to practice hand and respiratory hygiene, as well as cover coughs and sneezes. 'Individuals who are unwell with respiratory symptoms should practice regular hand washing, cover coughs and sneezes, and avoid contact with people who may be at high risk of severe respiratory illness,' it urged.
