Is it Strep A, RSV, a cold, flu or Covid? Guide to the symptoms every parent must know

SNIFFLES and coughs can all be symptoms of the common cold and are ever more present during the winter months.
But experts have warned that parents need to be more alert this winter, amid a rise in cases of Strep A.
On Saturday, it was revealed that a 12-year-old boy had become the first secondary school student to die of the Strep A bug which is sweeping the country.
On Friday, the UK Health Security Agency (UKHSA) said five children had died in England, with one child also having died in Cardiff, Wales.
In most cases it will cause mild illness, and can lead to conditions such as scarlet fever, which is flu-like and tends to occur in children - it can be serious if not treated swiftly with antibiotics.
Dr Colin Brown, Deputy Director, UKHSA said while the illnesses is uncommon, parents need to be aware.
He said: "We are seeing a higher number of cases of Group A strep this year than usual.
"The bacteria usually causes a mild infection producing sore throats or scarlet fever that can be easily treated with antibiotics. In very rare circumstances, this bacteria can get into the bloodstream and cause serious illness – called invasive Group A strep (iGAS).
"This is still uncommon however it is important that parents are on the lookout for symptoms and see a doctor as quickly as possible so that their child can be treated and we can stop the infection becoming serious.
"Make sure you talk to a health professional if your child is showing signs of deteriorating after a bout of scarlet fever, a sore throat, or a respiratory infection.”
But what are the symptoms you need to be on the lookout for and when should you see a doctor?
There are four key signs of Group Strep A to watch out for, according to the NHS. These are:
The invasive version of the disease happens when the bacteria break through the body's immune defences.
This can happen if you're already feeling unwell or have an immune system that’s weakened.
Two of the most severe examples of invasive disease are necrotising fasciitis - a very rare but life-threatening infection also called ‘flesh-eating disease’ - and toxic shock syndrome.
Speaking on Good Morning Britain today, Dr Amir Khan added that a sore throat is also a common symptom.
He added: "It's very difficult to tell the difference between that kind of infection of a cold or flu.
"But often the runny nose is absent with Strep so you don't have that kind of congestion."
Dr Khan said kids between the ages of 5-15 can get it, but added that it's most common in children under the age of 10.
In response to the outbreak, Downing Street said it can “fully understand” that parents are concerned by rising Strep A cases, but stressed the NHS is “well prepared” for such situations.
The Prime Minister’s official spokesman said: “We are seeing a higher number of cases of Group A strep this year compared to usual.
“The bacteria we know causes a mild infection which is easily treated with antibiotics and in rare circumstances it can get into the bloodstream and cause serious illness.
“It is still uncommon but it’s important parents are on the lookout for symptoms.
“But the NHS is well prepared to deal with situations like this, working with the UK Health Security Agency.”
He said any parents who are concerned should contact the NHS.
If you feel your child is seriously unwell you should trust your judgement and contact your GP if they experience any of the following:
Figures show that during the last high season for Strep A in 2017/18, there were four deaths in children under 10.

Data from the UKHSA released last week revealed that there has been an increase in cases of respiratory syncytial virus (RSV).
Figures show that the highest positivity rates are in children under the age of five.
Kids will often suffer with a runny or blocked nose, a cough and a slightly high temperature.
These include:
Both flu and RSV can be deadly in children.
RSV is usually mild but in serious cases, can lead to severe respiratory illness and pneumonia, which can be also deadly, guidance from the Centre for Disease Control (CDC), states.
In most cases, you can treat a cold without seeing a GP and the NHS says you should start to feel better within a couple of weeks.
The symptoms are usually the same in both adults and children, but experts say they could last a little bit longer in kids.
The says they can come on gradually and will often include the following:
When it comes to symptoms of flu, they may at first, seem like a common cold.
The NHS list the symptoms for flu as follows:
Children and young people can get Covid, but it's usually mild and most will get better within a few days, the NHS states.
There are a myriad of symptoms you might experience when it comes to the virus and these can include:
