Human noroviruses are the dominant cause of outbreaks of acute gastroenteritis. These viruses are usually detected by molecular methods, including reverse transcriptase PCR (RT-PCR) and enzyme-linked immunosorbent assay (ELISA). Human noroviruses are genetically and antigenically diverse, with two main genogroups that are further subdivided into over 40 different genotypes. During the past decade, genogroup 2 genotype 4 (GII.4) has dominated in most countries, but recently, viruses belonging to GII.17 have increased in prevalence in a number of countries...

The western South Atlantic (WSA) humpback whale population inhabits the coast of Brazil during the breeding and calving season in winter and spring. This population was depleted to near extinction by whaling in the mid-twentieth century. Despite recent signs of recovery, increasing coastal and offshore development pose potential threats to these animals. Therefore, continuous monitoring is needed to assess population status and support conservation strategies. The aim of this work was to present ship-based line-transect estimates of abundance for humpback whales in their WSA breeding ground and to investigate potential changes in population size...

A 66-year-old overweight insulin-dependent male passenger with diabetes and severe arthritis was on a 4-week circle-Pacific cruise. He fell ashore and hit his head. The ship was about to leave on a non-stop voyage - without any evacuation possibilities for the next 8 days. He was examined and had X-rays taken at the local hospital, but as his head injury was considered mild, he returned to the ship "for 48 hours of observation for signs of intracranial bleeding" - against the ship's doctor's advice. Delayed suspicion of a non-displaced cervical fracture caused extra work and worries and could have, but did not complicate matters...

A previously healthy 65-year-old female passenger presented on the 3rd day of her voyage with a small facial laceration after she fell and hit her forehead, following sudden blurred vision and dizziness. When the ship's doctor noticed that one pupil was much bigger than the other, he feared intracranial bleeding and considered helicopter evacuation. Her symptoms had started shortly after she had removed a transdermal scopolamine patch from behind her ear. Getting scopolamine from her hands in direct contact with the eye surface caused mydriasis...

Traditionally, cruise companies have stated that they are in the transport business but not in the business of providing medical services to passengers. They have claimed not to be able to supervise or control the ship's medical personnel and cruise ship's doctors have therefore mostly been signed on as independent contractors, not employees. A United States court decision from 1988, Barbetta versus S/S Bermuda Star, supported this view and ruled that a ship's owner cannot be held vicariously liable for the negligence of the ship's doctor directed at the ship's passengers...

OBJECTIVE: CDC routinely conducts contact investigations involving travelers on commercial conveyances, such as aircrafts, cargo vessels, and cruise ships. METHODS: The agency used established systems of communication and partnerships with other federal agencies to quickly provide accurate traveler contact information to states and jurisdictions to alert contacts of potential exposure to two travelers with Middle East Respiratory Syndrome Coronavirus (MERS-CoV) who had entered the United States on commercial flights in April and May 2014...

BACKGROUND: Long air travel is a risk factor for deep venous thrombosis (DVT). The aim of the study was to report the occurrence of symptomatic DVT cases in cruise ship passengers after long haul flights and to discuss applied diagnostic methods. MATERIALS AND METHODS: A retrospective analysis of medical records of adult patients diagnosed with DVT in medical facility of the passenger ship was performed. On the basis of clinical examinations, B-mode ultrasound scans of the lower extremity venous systems, international normalised ratio (INR) tests, working diagnoses of DVT were established...

With the increasing numbers of passengers and crew on board vessels that are becoming larger and larger, the demand for ship's doctors who can adequately treat burns on board has also increased. In the cruise ship industry it is usually those doctor's with internal and general medical training who are recruited from an epidemiological point of view. Training content or recommendations for the treatment of thermal lesions with the limited options available in ship's hospitals and where doctors with no surgical training operate do not yet exist...

Particulate polycyclic aromatic hydrocarbons, n-alkanes and polar organic compounds were investigated in the marine atmosphere of Southern and Eastern Mediterranean Sea, in the frame of the scientific cruise of Urania ship between 27 July and 11 August 2013. The PM10 fraction of aerosol to which most organic substances are associated, were collected daily; contemporarily, gaseous regulated toxicants (ozone, nitrogen oxides and carbon oxide) and carbonyls were recorded. Samplings were carried out in front of Palermo and Messina, respectively the start and end harbors, and along the cruise, both in movement (transects, N = 14) and at stops (N = 11)...

Severe air pollution and its associated health impacts have become one of the major concerns in China. A detailed analysis of PM2.5 chemical compositions is critical for optimizing pollution control measures. In this study, daily 24-h bulk filter samples were collected and analyzed for totally 21 field campaigns at 17 sites in China between 2008 and 2013. The 17 sites were classified into four groups including six urban sites, seven regional sites, two coastal sites in four fast developing regions of China (i...

We present results of validating the algorithms used to estimate sea surface solar radiation at 400-700 nm, photosynthetically available radiation (PAR), from satellite ocean color data and an appropriate validation procedure when data are collected using a moving ship. The validation was performed using field measurements of PAR during a transit cruise from the Baltic to the White Sea during the summer of 2014. The PAR was measured at 10-minute intervals using a deck radiometer throughout the daylight hours...

Noroviruses (NoVs), a group of nonenveloped, single-stranded RNA viruses belonging to the Caliciviridae family, are the leading cause worldwide of acute infectious gastroenteritis. Serious and eventual fatal outcomes may be observed in at-risk populations such as the very young or older adults, especially in those with underlying diseases. NoVs are highly infectious, with a low number of virus particles causing infection, and they are highly resistant to environmental conditions. NoVs have multiple routes of transmission including faecal-oral, aerosolized vomitus, person to person and via contaminated surfaces or food and water...

BACKGROUND: The Caribbean has one of the largest cruise ship industries in the world, with close to 20 million visitors per year. The potential for communicable disease outbreaks on vessels and the transmission by ship between countries is high. Barbados has one of the busiest ports in the Caribbean. Our aim was to describe and analyse the epidemiology of illnesses experienced by passengers and crew arriving at the Bridgetown Port, Barbados between 2009 and 2013. METHODS: Data on the illnesses recorded were extracted from the passenger and crew arrival registers and passenger and crew illness logs for all ships and maritime vessels arriving at Barbados' Ports and passing through its territorial waters between January 2009 and December 2013...

A test coupon coated with light calcareous tubeworm fouling was scanned, scaled and reproduced for wind-tunnel testing to determine the equivalent sand grain roughness ks. It was found that this surface had a ks = 0.325 mm, substantially less than the previously reported values for light calcareous fouling. This result was used to predict the drag on a fouled full scale ship. To achieve this, a modified method for predicting the total drag of a spatially developing turbulent boundary layer (TBL), such as that on the hull of a ship, is presented...

Based on observational analyses and on-site ground and aerial damage surveys, this work aims to reveal the weather phenomena-especially the wind situation-when Oriental Star capsized in the Yangtze River on June 1, 2015. Results demonstrate that the cruise ship capsized when it encountered strong winds at speeds of at least 31 m s(-1) near the apex of a bow echo embedded in a squall line. As suggested by the fallen trees within a 2-km radius around the wreck location, such strong winds were likely caused by microburst straight-line wind and/or embedded small vortices, rather than tornadoes...
