Airborne Disease On Cruise Ships

If 3 or more of the onboard population becomes sick within two weeks of a planned call on the US VSP officials will conduct an investigation.

Airborne disease on cruise ships. We find that airborne transmission likely accounted for 50 of disease transmission on the Diamond Princess cruise ship which includes inhalation of aerosols during close contact as well as longer range. The main route for transmission was considered to be from person-to-person but other routes should not be neglected such as aerosol transmission via central air supply or drainage systems 50. New diseases might surface in unexpected locations.

Influenza A outbreak on a cruise ship. People joining the ship may bring the virus to other passengers and crew. The risk of diarrhoeal disease outbreaks on cruise ships appears to have decreased since implementation of the VSP but has not been eliminated and seafood cocktail was implicated in 8 of 13 documented food-borne outbreaks.

Close contact transmission was likely happening on that cruise ship but the disease had spread far more quickly than non-airborne diseases typically spread. The median cruise ship passenger is over 45 years old and often has chronic medical problems so it is important that to have a safe cruise ship experience any potential for the introduction of an infecting agent as. This study integrated an individual-to-individual probability model a susceptible-exposed-infected-recovered SEIR epidemic model at the individual scale and an onboard indoor social contact network model for evaluating the infection risk on a typical cruise ship voyage.

The study found the risk associated with transmission of airborne particles between spaces through the HVAC system is exceptionally low and undetectable.

Vectorborne Diseases Cruise ship port visits may include countries where vectorborne diseases such as malaria dengue yellow fever Japanese encephalitis and Zika are endemic.

In the current outbreak the Diamond Princess cruise ship is a study case for the propagation of the disease. Close living quarters may increase the amount of group contact. Looking at infection data from the ship the London School of Hygiene and Tropical Medicine has hypothesized how things could have gone differently.

The first deaths were reported Thursday. In the HBO documentary the ships doctor reiterates that by February 9th he was sure that people without symptoms were infecting others. An infectious agent introduced into the environment of a cruise ship has the potential to be distributed widely across the ship and to cause significant morbidity.
