  Doctors in the US have confirmed their first case of a patient becoming reinfected with Covid-19.

  The 25-year-old man, who has not been identified, first tested positive in April after showing mild symptoms of a sore throat, cough, headache, nausea and diarrhoea.

  But, after recovering and receiving two negative tests, he began experiencing similar warning signs in May.

  He tested positive 48 days after the first negative test and suffered a more severe infection.

  This time he was hospitalized, required oxygen, and endured coughs, muscle aches and shortness of breath. An X-ray also showed he had viral pneumonia, which can be fatal.

  Genetic sequencing reveals the patient, of Washoe County in Nevada, was infected by two different strains of coronavirus. He is thought to be the world’s fifth known case of Covid-19 re-infection.

  The truth on COVID-19 immunity remains a mystery because the pathogen, known as SARS-CoV-2, has only been known to science for less than a year. But scientists are convinced the disease will be milder the second time round because the body will have already built up some natural immunity against it.

  The latest case published in the Lancet challenges that theory and poses serious questions for any future vaccination program, as well as those countries pushing a her immunity strategy.
