The fight is on

Apr 21, 2021

The flu isn’t really anything to sneeze at. Each year in South Africa it kills about 10,000 people, those five years and older. While that’s a relatively small number compared with the past year’s Covid-19 deaths, it’s still a heavy toll.

Comparing COVID and the flu

Whilst influenza (Flu) and COVID-19 are both contagious respiratory illnesses, they are caused by different viruses. COVID-19 is caused by infection with a new coronavirus (called SARS-CoV-2), and flu is caused by infection with influenza viruses. Like SARS-CoV-2, flu is transmitted by hitching a lift on droplets from the upper respiratory tract, and by people transferring virus-carrying droplets by hand from surfaces to their nose, mouth and eyes. COVID-19 seems to spread more easily than flu and causes more serious illnesses in some people. It can also take longer before people show symptoms and people can be contagious for longer.

The impact of COVID-19 on the flu

Just like Covid-19, the flu virus transmission is prevented through masking, physical distancing, avoiding poorly ventilated indoor areas, good hand hygiene, and isolating. Therefore, unsurprisingly, many fewer cases of the flu were reported in 2020 than usual – both during lockdown and afterwards. This is no doubt due to the COVID hygiene practises in place. You may have even noticed that you haven’t had the same number of colds over the past year?

What this tells us is that basic principles are effective in preventing the transmission of germs that cause the common cold, the flu and even COVID-19. This is important because, as winter approaches, we don’t want to be faced with the prospect of a “double disease whammy”, COVID plus the flu.

Preventing a “double whammy”

While wait for the roll-out of the COVID-19 vaccine to gather some pace, here are 3 other ways you can improve your overall health and lower the risk of catching COVID-19 or the flu this winter.

Follow basic COVID regulations
- Wash your hands
- Sanitise
- Wear a mask
- Social distance
- Don’t attend large gatherings

Maintain a healthy immune system
- Eat well
- Move more
- Make sleep a priority
- Manage your stress
- Expose yourself to some daily sunshine

Get vaccinated: have an annual flu jab and accept a COVID jab when it becomes available.

Both the flu vaccine and the COVID vaccine are safe and effective. By having the flu jab, your risk of developing any severe complications, if you do happen to get flu, is reduced. This means you won’t be putting any strain on the health system. It also means that if you DO present with severe complications, your doctor can more easily exclude flu as a possible factor. Secondly, it lowers your risk of getting flu which automatically lowers your immunity. With a lower immunity you’re more likely to pick up other infections… and in this case, COVID. Little information is available on the severity of COVID-19 and other viral co-infections. But a recent report suggests that influenza and COVID-19 co-infections may result in more severe disease in high-risk patients and complicate the diagnoses.

5 surprising facts about ADHD

Think attention-deficit/hyperactivity disorder (ADHD) is shorthand for someone who can’t sit still and focus?
In fact, it’s not an inability to focus, it’s about regulating attention. Many people with ADHD describe becoming intensely focused on some tasks – known as ‘hyperfocus’ – while struggling to start or complete things that don’t grab their attention.

When breastfeeding does not work for you

Breastfeeding is often portrayed as one of the most natural parts of motherhood – an instinctive, nurturing interaction between mother and child. But what if that image of effortless nursing doesn’t reflect your reality?
You’re not alone. In fact, 60-80% of new moms say they have difficulty breastfeeding. What’s more, in South Africa, the tally for infants under six months that are exclusively breastfed is less than one in three.

Why you should start building bone today

Over the years, your bones gradually break down – and for women after menopause, it’s a particularly big problem.
Your bones may seem solid, but they’re actually living tissue constantly renewing itself – like a well-maintained building. New parts replace old ones all the time, but if the building loses more bricks at a rate than they can be replaced, the structure becomes weaker.
