Current Illness Trends: What’s Happening?
Feeling under the weather? If you’re not, chances are you know someone who is—or has just bounced back. It’s clear that coughs and colds are going around.
From the chatter I’ve picked up, it appears that the bug circulating is quite a tough one this season. Symptoms like sore throats? Check. Runny noses? Definitely. Sinus pressure? A resounding yes.
So, what exactly is going on?
The Perfect Breeding Ground
“This is typical for autumn,” says Prof Jonathan Ball from the Liverpool School of Tropical Medicine. He explains that a mix of kids returning to school, adults back at work, and people clustering indoors as the weather cools creates a fertile environment for respiratory viruses.
Essentially, it’s like a big melting pot of different viruses making their rounds. With immunity levels dropping, more folks are getting sick.
Believe it or not, there are over 100 different viruses that can lead to upper and lower respiratory infections, not to mention various bacterial infections.
Are More People Getting Sick than Usual?
According to the UK Health Security Agency (UKHSA), data indicates that Rhinovirus—the common cold—has risen recently, becoming the primary culprit behind current illnesses.
Covid remains present as well, fueled by two new variants—XFG, sometimes referred to as Stratus, and NB.1.8.1, known as Nimbus. Thankfully, there’s a healthy level of immunity in the population, so most cases seem relatively mild.
Flu might be on an upward trend too, particularly among those aged 15-25, and RSV usually spikes in young children during the autumn.
“There’s often a pattern, though not a strict one,” comments Dr. Jamie Lopez Bernal, a consultant epidemiologist at UKHSA. He notes that Rhinovirus often spikes first, with RSV following, and flu typically peaks in December or January—but that has changed since the pandemic. Recent trends appear to be stabilizing to some extent.
As for now, Dr. Bernal mentions that illness levels aren’t particularly alarming. “Covid is above the baseline, and quite a bit of Rhinovirus is circulating. The flu uptick in the younger demographic seems a bit earlier than expected, but it’s still at a manageable level.”
Identifying the Bug: Cold, Flu, or Covid?
Here are some common signs to help you distinguish between them, per the NHS:
Colds
- Symptoms develop gradually
- Affect mainly the nose and throat
- Early sign may include ear pressure
- More mucus in cough
Flu
- Onset is sudden
- Feels like being completely wiped out
- Symptoms include fever, muscle aches, and fatigue
- Usually requires bed rest
- Typically involves a dry cough
Covid
- Shares symptoms similar to flu
- Loss of taste or smell is a unique indicator
- Can include digestive issues
The symptoms between colds, flu, and more severe viruses like Covid often overlap, making it tricky to figure out what’s what.
Staying Safe
Respiratory infections can pose serious risks, especially for vulnerable people—during harsh winters, flu can contribute to thousands of deaths.
However, there’s no solid evidence that the current circulating respiratory viruses are causing more severe illness among otherwise healthy individuals.
“We all react differently, and it’s not entirely understood why,” acknowledges Prof Ball. Factors like age and health do play a role—but genetics, fatigue, and prior exposure to the virus can also influence how one feels.
For protection, getting vaccinated is a crucial step if eligible. Vaccines for flu, Covid, and RSV are available for those at risk, including the elderly and those with specific health conditions.
If you’re sick, the UKHSA suggests washing your hands diligently, especially after sneezing or coughing, staying home if possible, and wearing a mask when out in public.
Prof Ball advises that while it’s wise to take precautions for vulnerable populations, it’s also normal for healthy individuals—especially the young—to catch respiratory infections from time to time. “Most people get one or two respiratory bug each year, and that can actually be beneficial,” he explains. “Exposure helps build immunity, so when you’re older, you’ll hopefully be less at risk of severe illness.”
