A mum has urged parents to look out for symptoms of coronavirus after her two young children suddenly fell ill.
The family, from Fussen, in Germany, had been playing in the garden on a warm day and had appeared "fine".
But it wasn't until the evening and both children began to shiver and break out in a sweat - and just two hours later their temperatures soared to more than 40 degrees.
In the space of 24 hours they developed a dry cough and the worried mum was forced to contact her doctor so they could be tested.
The two children tested positive for coronavirus and were taken to hospital after their condition deteriorated.
Bettina said: "On that day when they were positive, the health authorities called us and I said, ‘Look, I don't know what to do. I can't control their temperatures. They are starting to drink less and less’".
Bettina, who was allowed to self-isolate in hospital with her children, explained that Charlotte stopped being able to taste.
She explained that both her children's white blood cells were so low it meant they had no immune system left at all - and that they were lucky it didn't spread to the lungs and cause pneumonia.
She said: “They are always saying kids don't get sick. Now you are in hospital with both of your kids. You feel very, very lonely. Very scared.”
Andrew Steer, who leads the infection and immunity research team at the Murdoch Children's Research Institute in Melbourne, said: "Because the disease appears to be mild in children, it may be actually that there are more cases in children".
Charlotte and Frederick have now recovered from the virus.
Both Bettina and her husband have no idea where their children could have picked up the virus - but think it could have been brought home from the shops or in kindergarten before lockdown.
Bettina and her husband shared their story to inform parents about the symptoms in the hopes that they can catch the virus early on.
