||World travel is increasing annually, also refugees and forced
migrations are increasing due to regional wars, economic
downturn or opportunities (1) At the turn of the 19th century an
epidemic of TB on the Eastern Seaboard of the USA was due to
waves of European immigration into cheap slum housing. So great
was the demand for passages to the US that a whole fleet of fast
steamships were built. The most famous of these was The Titanic.
Had the Titanic not sank, many of her steerage passengers would
have reached New York, and a new life, only to die of TB.
