Doctors have revealed science-backed advice for children avoiding September illnesses, as viral infections spread around classrooms. At the start of every academic year, schools become a breeding ground for coughs, colds, and contagious bugs. Data shows that Hand, Foot and Mouth cases peak between weeks 40 to 43 of the year, while Google searches for symptoms have surged 101% this quarter alone.
Last September, rhinovirus infections spiked by more than 30% during the same time period, according to the UK Health Security Agency (UKHSA). Superdrug Online Doctor has shared GP Dr Babak Ashrafi’s advice on practical, science-backed tips for parents who want to protect their children’s immune systems during this seasonal surge. “We always talk about sleep and diet – but there are other, lesser-known ways to support children’s immune systems that can make a real difference when school bugs start circulating,” Dr Ashrafi said.
His top four recommendations give families easy, everyday tools to fight infection before it takes hold.
Firstly, Dr Ashrafi said to “let them play dirty” as outdoor exposure to natural microbes, such as trees and grass, can build a stronger immune system. Kids who play in nature have more diverse gut bacteria, which helps fight illness long-term.
Next, “feed their gut the good stuff”. Even just a few spoonfuls a day of fermented foods can help kids build a stronger, calmer gut, the GP said, and in turn, a more resilient immune system.
Swapping sugary yoghurts for drinkable kefir, or mixing plain Greek bioactive yoghurt with honey and berries as a dessert, can feed good gut bugs.
Dr Ashrafi also says to simply establish a solid handwashing routine at home by making it fun with a favourite soap scent or a foaming pump, sticker charts, or rewards for consistency.
Practising now gives kids time to form muscle memory and habit, so it’s second nature for when they’re at school or nursery.
Finally, the GP said to stay up to date with vaccinations by checking your child’s NHS vaccination record.
This includes ensuring they’ve had both doses of the MMR vaccine to protect them against measles, mumps and rubella when school begins again.
Dr Hana Patel added: “When vaccines are missed, children lose a vital layer of protection against diseases that can spread quickly in schools.
“Viruses like measles are highly contagious – one infected child can spread it to 9 out of 10 unvaccinated classmates. For children, these infections can cause serious complications, from pneumonia to long-term neurological problems.”
