Teen climate activist, Greta Thunberg says she may have contracted coronavirus and has self-isolated at home with her father. In an Instagram post she said she both her and her father, actor Svante Thunberg, were infected.

She said they both began having symptoms after a recent train tour of Europe together. She said she experienced shivers, a sore throat, a cough and felt tired after travelling with her father from Brussels.

She did not get tested, however, because she said in Sweden you could not get tested for COVID-19 unless you were in need of emergency medical treatment.

Thunberg said in an Instagram post that she self-isolated in an apartment away from her sister and mother after noticing symptoms 10 days ago.

View this post on Instagram The last two weeks I’ve stayed inside. When I returned from my trip around Central Europe I isolated myself (in a borrowed apartment away from my mother and sister) since the number of cases of COVID-19 (in Germany for instance) were similar to Italy in the beginning. Around ten days ago I started feeling some symptoms, exactly the same time as my father – who traveled with me from Brussels. I was feeling tired, had shivers, a sore throat and coughed. My dad experienced the same symptoms, but much more intense and with a fever. In Sweden you can not test yourself for COVID-19 unless you’re in need of emergent medical treatment. Everyone feeling ill are told to stay at home and isolate themselves. I have therefore not been tested for COVID-19, but it’s extremely likely that I’ve had it, given the combined symptoms and circumstances. Now I’ve basically recovered, but – AND THIS IS THE BOTTOM LINE: I almost didn’t feel ill. My last cold was much worse than this! Had it not been for someone else having the virus simultainously I might not even have suspected anything. Then I would just have thought I was feeling unusually tired with a bit of a cough. And this it what makes it so much more dangerous. Many (especially young people) might not notice any symptoms at all, or very mild symptoms. Then they don’t know they have the virus and can pass it on to people in risk groups. We who don’t belong to a risk group have an enormous responsibility, our actions can be the difference between life and death for many others. Please keep that in mind, follow the advice from experts and your local authorities and #StayAtHome to slow the spread of the virus. And remember to always take care of each other and help those in need. #COVID #flattenthecurveA post shared by Greta Thunberg (@gretathunberg) on Mar 24, 2020 at 8:22am PDT

She added that she wanted to raise awareness about how easy it was to transmit the infection without realising.

She wrote: ‘I didn’t basically feel that I was ill. It could be that I was feeling unusually tired, I was coughing a bit.

‘That is because I’m not in a risk group, I didn’t get it very seriously. That also is very dangerous because you don’t know you have it.

‘If I wouldn’t have been for my father getting it at the same time and much more intense than me, I might not even have noticed it that I was sick.’

‘Many people don’t feel symptoms at all, or very mild symptoms, but it can be contagious.

Thunberg and her father were travelling in Europe before lockdowns were imposed by many governments across the continent to help contain the spread of coronavirus.
