Athletes from Germany and Canada were among those who stayed at the Tower Hotel in London who got sick last week.
"There have been a number of cases of gastroenteritis reported by team members residing within one of the official team hotels for the world championships", the organizing committee said earlier in a statement.
Three people associated with the Athletics World Championships have contracted the norovirus with another 40 reporting symptoms, Public Health England (PHE) announced on Thursday.
"Those affected have been supported by both team and LOC [Local Organizing Committee] medical staff, in addition we have been working with Public Health England to ensure the situation is managed and contained".
The Tower Hotel said investigations conducted by environmental health officers and the International Association of Athletics Federations (IAAF) had shown the hotel was "not the source of the illness".
A hotel spokesman added: "We have followed strict hygiene protocol".
