 There is a contending belief that the disease actually spread to the "Lev Berg" from Uyaly or Komsomolsk-on-Ustyurt, two cities in what is now Uzbekistan where the ship docked.The incident caused ten individuals to contract smallpox and three unvaccinated individuals (a woman and two children) died from the haemorrhagic form of the disease.One crew member of the "Lev Berg" contracted smallpox as the ship passed within 15 km (9 miles) of the island.
