17-year old so-called climate activist, Greta Thunberg claimed that she and her father Svante might have contracted the deadly COVID-19 virus.

Without undergoing tests, the teenager recklessly claimed that she might have been infected by the virus after she exhibited some of its signs and symptoms. In her social media post on Tuesday, Thunberg wrote to her 10 million followers that young people might unknowingly have the virus and pass it on others.

She then went on to discuss in length her personal experience. Thunberg explained that ten days ago, she started to feel some symptoms related to Covid-19, such as tiredness, shivers, sore throat, and cough. She cited that she might have contracted it from her father, who came from a trip to Brussels, saying that he also shared the symptoms, although it was “much worse.”

Thunberg and her father decided to stay in self-isolation after they returned from a trip to Central Europe, which also has an increasing number of COVID-19 patients. They borrowed a nearby apartment away from her mother and sister in fear of infecting her other family members.

Thunberg then urged young people to stay at home even if they might not feel sick or do not share any symptoms. “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,” she wrote.

The teenager, who was best known for encouraging street protests and schooling other world leaders on the effects of climate change, had earlier claimed during a UN climate change summit in New York that she wouldn’t waste her time speaking to President Donald Trump. At the same event, Thunberg also shot angry looks at the US president while he was making his speech.

She accused Trump of not listening to leading “scientists and experts,” and continues to brand him as a climate denier. The president shot back, saying that Thunburg needs to work on her anger management problems. However, the teenager has, in fact, had a developmental disorder known as Asperger’s, which made it difficult for her to socialize as well as empathize with others.
