Plagued by THAT never-ending cough? What experts say you can do to beat your stinking cold



We expect to get colds over the winter, but this season it seems many people are really struggling to get rid of their sniffles.

Is there a particularly long-lasting virus circulating, are we just catching back-to-back bugs, or is this inability to shake off winter ailments simply a result of reduced immunity after the pandemic?

Ron Eccles, an emeritus biosciences professor at Cardiff University, and the former director of its Common Cold Centre, says winter is the most likely time of year for catching colds – especially as children have returned to school and nursery and viruses are spreading easily among them and then their parents.

‘There are also more colds in winter, and the wet weather has kept us indoors and the damp has helped viruses survive better,’ he adds. ‘There are complaints about never-ending colds, and this may be due to multiple infections, or us being more run down and stressed at this time of year after festive excess.’

He points out that Covid is still around too, adding: ‘If you’re suffering from a stinking cold, it’s better to keep away from anyone who could be immune-compromised as the other cold viruses can also cause serious disease in the vulnerable elderly.’

Are colds really getting worse?

Jeremy Brown, a professor of respiratory infection at University College London (UCL), says there’s no clear data on whether any long-lasting viruses are circulating, as very little information is collected about the duration of infectious symptoms.

He notes that some people’s symptoms could be caused by Covid, adding: ‘Covid is pretty indistinguishable from other respiratory viruses. It can make people feel pretty rotten – more so than standard cold viruses, but perhaps no more so than flu.’

The common symptoms of Covid haven’t changed drastically – fever, sore throat, runny nose, cough and sometimes gastrointestinal symptoms such as diarrhoea are all typical, and prolonged symptoms range from dizziness and breathlessness to changes in our senses of smell and taste.

The pandemic may have played a part

Professor Brown says it is possible that viral infections have become worse or more prolonged after the pandemic, but he adds: ‘There’s been what seems like a bounce-back with frequency of infection with some respiratory viruses, although it’s always hard to be sure as their incidence varies year to year anyway. 

‘This is not Covid impairing immunity, but lack of exposure to respiratory viruses weakening adaptive immunity to the viruses so they can more readily infect when they’re circulating.’

Similarly, GP Dr Alisha Esmail says: ‘One theory about lingering cold symptoms is the “post-Covid effect”, in that we had less exposure to the classical winter viruses due to quarantining and isolating, and so we’re catching up now on rebuilding our immune responses.

‘Remember, viruses mutate and immune responses fade over time. Our individual immunity also has a huge number of factors – some within and some beyond our control.’

Figures released by the Office for National Statistics and UK Health Security Agency in December showed symptoms including headaches, a runny nose and coughing were among three of the most common Covid symptoms reported in the week ending December 13. Other frequently logged symptoms also included muscle ache, a sore throat and tiredness

Could something else be going on?

Some people report having a long-lasting cough, dubbed the ‘100-day cough’. This is thought to actually be whooping cough in some cases. 

Professor Brown explains: ‘100-day cough is classic whooping cough – it’s exactly as it says, a dry cough that goes on for three months, but not really with sore throat, runny nose etc, just a cough.’

Dr Esmail explains that the most common cold viruses currently circulating are coronavirus, rhinovirus, respiratory syncytial virus (RSV, common in children), and para-influenza, but says: ‘As far as we know, there are no new or particularly virulent viruses at play this winter, but all have different subtypes and can easily mutate, hence the possibility of catching them multiple times and in different ways.’

She says a typical cold usually lasts about seven to ten days, and the severity of symptoms can depend on the virus as well as the affected person’s individual immune response. But if symptoms persist beyond three weeks, worsen suddenly, or you have a high fever or breathing trouble, a GP visit is a smart move.

‘Resting, keeping well hydrated and using over-the-counter treatments could shorten its stay, but if you’re still sniffling after three weeks, it’s time to take some action,’ she advises.

Also, if symptoms really do linger, Dr Esmail says there’s a chance it might be connected to seasonal allergies, sinus infections, underlying wheeze (as with asthma) or even ‘bacterial gate-crashers’ – i.e. bacteria that have jumped on board, in which case, antibiotics may be needed (but these won’t help if it’s a virus).

Dr Esmail, who works at the London Gynaecology private clinic, says lack of sleep, poor nutrition and high stress levels can also prolong illness and weaken the immune system, and stresses that if symptoms persist for a long time, it’s worth visiting your GP.
