People living in areas where the Delta variant of the coronavirus, first recorded in India, is spreading should look out for different symptoms to other strains, doctors say.

The Delta variant is proving more infectious than earlier strains.

Earlier this year, data from Public Health England indicated more than 90 per cent of new Covid-19 cases in the UK are the Delta variant.

Paul Hunter, professor of medicine at the University of East Anglia in the UK, told The National that clinicians have reported different markers for the virus among recently infected people.

This means that the first thing someone may now experience when catching Covid-19 is not the familiar cough.

So what should you look out for?

What are 'normal' Covid-19 symptoms?

Most people who are infected with Covid-19 will experience a dry cough, a fever and loss of smell and taste.

What is the Delta variant?

Delta is the name given to the variant first detected last October in India.

There, it caused a devastating second wave of cases and led the UAE to bar nearly all passengers from travelling from India to the Emirates.

The Delta variant has spread to many countries around the world and has been blamed in particular for surges of cases in the UK and Russia.

British authorities have said the Delta variant was "60 per cent more infectious" than the Alpha strain, first detected in the UK.

Is the Delta variant in the UAE?

The World Health Organisation stated last week that the Delta strain was now present in 132 countries, one of which is the UAE.

At a Covid-19 briefing held at the end of June, officials said Delta accounted for one in three new cases of Covid-19 across the Emirates.

Data at the time found the Beta strain was the most prevalent – at 39.2 per cent – followed by Delta at 33.9 per cent and lastly Alpha with 11.3 per cent.

Current vaccines are “not quite as effective” at preventing illness in people infected with the Delta variant, but do still work, said Dr Andrew Freedman, an infectious diseases specialist at Cardiff University in the UK.

People who have had a full course of two injections of the Pfizer-BioNTech vaccine are 88 per cent less likely to develop symptomatic illness if they subsequently become infected with the Delta variant, compared with 93 per cent less likely with the Alpha variant.

When it comes to preventing hospital admission, two doses of the Pfizer-BioNTech shot are 96 per cent effective against the Delta variant, according to Public Health England data.


How do Delta variant symptoms differ?

Prof Hunter said doctors were reporting different symptoms.

“You’re getting more cold-like symptoms, sore throat and sneezing,” he said.

Fever remains quite common, but he said that damage to the sense of smell was not being reported with the Delta variant.

Headaches and a runny nose are being recorded as common symptoms.

Why might the symptoms be changing?

The Delta variant may cause the body to react differently, said Prof Hunter.

“This doesn’t surprise me because if you look at the other human coronaviruses – there are mainly four – they essentially cause the common cold in most of us.”

It is also possible that some of those infected with the Delta variant have previously been infected or had a vaccine.

Therefore, they are experiencing different symptoms because they already have the antibodies to fight off the virus.

Why is this important?

If people think they merely have a head cold, then they might not think to test for Covid-19.

This results in an increased number of infected people going about daily life and spreading the virus.

Parents may presume their child simply has a sniffle and send them to school.

This can lead to Covid-19 spreading quickly within the community.

Doctors recommend taking a PCR test as a precaution.

Tearful appearance

Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday. 

Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow. 

She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.

A spokesman said her upset demeanour was due to a personal matter.

Tips for used car buyers
  • Choose cars with GCC specifications
  • Get a service history for cars less than five years old
  • Don’t go cheap on the inspection
  • Check for oil leaks
  • Do a Google search on the standard problems for your car model
  • Do your due diligence. Get a transfer of ownership done at an official RTA centre
  • Check the vehicle’s condition. You don’t want to buy a car that’s a good deal but ends up costing you Dh10,000 in repairs every month
  • Validate warranty and service contracts with the relevant agency and and make sure they are valid when ownership is transferred
  • If you are planning to sell the car soon, buy one with a good resale value. The two most popular cars in the UAE are black or white in colour and other colours are harder to sell

Why are asylum seekers being housed in hotels?

The number of asylum applications in the UK has reached a new record high, driven by those illegally entering the country in small boats crossing the English Channel.

A total of 111,084 people applied for asylum in the UK in the year to June 2025, the highest number for any 12-month period since current records began in 2001.

Asylum seekers and their families can be housed in temporary accommodation while their claim is assessed.

The Home Office provides the accommodation, meaning asylum seekers cannot choose where they live.

When there is not enough housing, the Home Office can move people to hotels or large sites like former military bases.

Going grey? A stylist's advice

If you’re going to go grey, a great style, well-cared for hair (in a sleek, classy style, like a bob), and a young spirit and attitude go a long way, says Maria Dowling, founder of the Maria Dowling Salon in Dubai.
It’s easier to go grey from a lighter colour, so you may want to do that first. And this is the time to try a shorter style, she advises. Then a stylist can introduce highlights, start lightening up the roots, and let it fade out. Once it’s entirely grey, a purple shampoo will prevent yellowing.
“Get professional help – there’s no other way to go around it,” she says. “And don’t just let it grow out because that looks really bad. Put effort into it: properly condition, straighten, get regular trims, make sure it’s glossy.”
