The coronavirus pandemic has affected people in different ways ranging from fear to boredom, depression and deep introspection. However, something seems to have got into the brains of world number one tennis player, Novak Djokovic, and his wife, Jelena, who have both been accused of spreading misleading information about the virus.

Starting with the tennis star himself, who has long had an interest in spiritual and medical matters, and has been an advocate of natural healing over conventional medicine. He has said that, if there were a requirement for all players to have a vaccination against the disease – should one be available in time – before playing again, he would be averse to the idea, and that the concept would make him think twice before returning to competitive action again.

His comments have been slammed by Professor Pedrag Kon, a leading epidemiologist and advisor to the Serbian government, as sending out the completely wrong message about the benefits of mass immunisation to the millions of people in the country who look up to Djokovic as the country’s biggest sporting star.

Nor is he the only way in the Djokovic household who appears to have unusual theories about the coronavirus. His wife Jelena has shared a 10 minute video on her Instagram account of an American professor discussing the spurious links between the spread of the coronavirus, and the roll-out of 5G technology.

(Such reports have seen aerials and mobile phone masts attacked in a number of country by zealots believing they are being used to spread Covid-19).

In the case of Jelena Djokovic, though, following a number of complaints, fact checkers from Instagram then reviewed the video and now, every time that anybody goes to view the post, a message flashed up warning that this is false information.

The 33 year old has attempted to defend herself by claiming that the subject was of interest to her but, without overtly endorsing the views expressed in the video, she has so far refused to take the post down.
