english: We don't know why ME sometimes runs in families, why you can get it after almost any infection, from enteroviruses to Epstein-Barr virus to Q fever, or why it affects women at two to three times the rate of men.
non_english: Ne znamo zbog čeka se SHU ponekad prenosi u porodici, zašto ga možete dobiti posle skoro bilo koje infekcije od enterovirusa do Epštajn-Barovog virusa i kju groznice. Ne znamo ni zašto 2 do 3 puta češće napada žene.
