Rotavirus surge in South Africa: What parents need to know about signs, prevention and hydration

People across South Africa are currently talking a lot about rotavirus because there has been a sudden and worrying spike in severe diarrhea cases among young children in several provinces. This health concern is trending because many parents have taken to social media platforms like Facebook and X to share stories of long queues at clinics and hospitals, especially in Gauteng and the Western Cape. The Department of Health and medical experts are now urging families to be extra careful with hygiene as the change in weather seems to be making the situation worse for our little ones.

Understanding the recent rotavirus surge in our communities

The reason why rotavirus is making headlines right now is that it is the leading cause of severe, dehydrating diarrhea in infants and young children worldwide. In South Africa, we usually see these peaks during the colder months or when the seasons change. Doctors are explaining that while most children get the vaccine as part of the normal government health road-to-health schedule, the virus is still very strong and can spread easily in crèches and schools where kids share toys and touch the same surfaces.

Many moms and dads are sharing their heart-breaking stories online about how fast their children got sick. It usually starts with a fever and vomiting, followed by very watery diarrhea that can last for several days. Because it spreads through the “fecal-oral” route, which is a fancy way of saying it spreads when people don’t wash their hands properly after changing nappies or using the toilet, it can move through a household or a classroom in just a few days.

Health experts from the NICD have reminded the public that the best way to fight this is through prevention. They are encouraging parents to make sure their children’s vaccinations are up to date. Even though a vaccinated child can still get the rotavirus, the vaccine usually makes the sickness much milder, so the child doesn’t end up in a hospital bed on a drip. It is all about making sure our kids stay hydrated with oral rehydration salts while their bodies fight off the germ.

Common questions about the virus

• What are the first signs I should look for? Usually, it starts with a sudden fever and vomiting, followed by very watery diarrhea that happens many times a day.
• How does the virus actually spread? It spreads through contaminated hands, toys, or food. If a person touches something with the virus on it and then touches their mouth, they can get sick.
• Can my child still get it if they were vaccinated? Yes, but the vaccine is very good at preventing the “severe” version of the illness. This means your child might get a runny tummy but is much less likely to get dangerously dehydrated.
• Is there a specific medicine to kill the virus? No, because it is a virus, antibiotics won’t work. The main treatment is keeping the child hydrated with plenty of fluids like Rehydrat or similar solutions.
• Can adults catch this too? Yes, adults can get infected, but usually, the symptoms are very mild because their immune systems are stronger. However, they can still pass it on to babies.
• When must I take my child to the emergency room? You should go immediately if your child cannot keep any liquids down, has no tears when crying, has a very dry mouth, or seems unusually sleepy and floppy.
