An urgent letter is being issued to all parents warning them not to get their children tested for coronavirus if it's likely their little one could just have a cold.

The letter, which will be sent to parents via their child's school, is from NHS Test and Trace and tells parents their child does not need a Covid-19 test if they simply have a runny nose and are sneezing.

The letter warns: "Every time a test is used inappropriately, a person with Covid-19 symptoms may miss out on getting tested."

Whilst the letter stresses that testing for coronavirus is important to ensure the safety of pupils and parents, - it says parents "have a duty to make sure that the right people have access to get tested" - meaning they should not be wasted on children who have a cold.

When should I get my child tested for coronavirus?

The letter tells parents their child only needs a test if they have any of these three coronavirus symptoms:

The letter goes on to say a child does not need a test if they have a runny nose, are sneezing of sneezing or feeling unwell but do not have a temperature, cough or loss of, or change in, sense of smell or taste - because these are "not normally symptoms of coronavirus."

It comes after dozens of parents told Hull Live their children had been sent home from school with a "sniffle", with schools requesting a negative test before they could be let back into the classroom.

Jay-Jaye Elgar, five, from west Hull was sent home from school after coughing in class, but his parents refused to have him tested because they said they knew it was just a cold.

Parents are also reminded in the letter that only the person with symptoms should get a test.

The letter says: "You do not need to get a test for anyone else in the household unless they also have any of the three symptoms listed above.

"All members of the household need to self-isolate whilst waiting for the test result.

"If the person with symptoms’ test comes back positive, other members of their household should continue self-isolating for 14 days and only get a test if they develop coronavirus symptoms."

The letter also explains the importance of self isolating.

It says: "Contacts of a person who has tested positive must follow the guidance carefully and in full, which means they must stay at home for 14 days.

"This is because it can take several days following contact with an infected person before an individual develops symptoms or the virus can be detected. Students should only book a test if they get symptoms."

If parents are unsure about whether to get a test, they should check the official list of symptoms on the NHS website, which is reviewed regularly here.
