Two seafarers have died and another is in hospital as Brazil's dire Covid-19 emergency spread to three vessels.

These are only the second and third known coronavirus deaths reported on ships worldwide following the loss of a master on a CSL Group bulker, the 11,500-dwt Tertnes (built 1985), off Norway in March.

Brazil's health agency Anvisa said a 63-year-old Filipino crew member was taken to hospital from the 82,000-dwt Vita Future (built 2015) in Santos, Sao Paulo state, on 5 April.
