Jing Li, Xiuxian Song, Yue Zhang, Jun Pan, Zhiming Yu
Previous studies suggested that the removal of Ulva microscopic propagules (UMP) from cradle water might restrict the formation and expansion of green tides in the Yellow Sea, China. In this study, the distribution characteristics of UMP in the southern Yellow Sea was investigated, and then a flocculation experiment of UMP using modified clay (MC) was conducted at a selected station of the research cruise. The results indicated that the distribution of green algae thalli is one of the main factors that directly influence UMP distribution...

BACKGROUND: Influenza viruses are among the major causes of serious human respiratory tract infection worldwide. In line with the high disease burden attributable to influenza, these viruses play an important, but often neglected, role in travel medicine. Guidelines and recommendations regarding prevention and management of influenza in travellers are scarce. Of special interest for travel medicine are risk populations and also circumstances that facilitate influenza virus transmission and spread, like travel by airplane or cruise ship and mass gatherings...

A firm handshake is a widely used greeting, but contaminated fingers and palms can also transfer bacteria and virus. Hand sanitation is important to prevent spreading of contagious diseases, but to wash hands properly takes too much time to ensure satisfactory compliance. Banning the handshake from health care settings has been proposed, but an alternative, less contagious form of greeting must be substituted. Cruise ships are particular vulnerable to infectious diseases that are transferred from person to person...

Antarctic tourism on board cruise ships has expanded since the 1990s, essentially in the Antarctic Peninsula. Due to remoteness, medical cases may evolve into life threatening conditions as emergency medical evacuations are challenging. We discuss the case of a young crew member who suddenly fainted with an epigastric pain and abundant rectal bleeding while on board a cruise ship heading to the Deception Island (62°57.6 South, 60°29.5 West), 44 h away from Ushuaia by sea. A medical evacuation was necessary to save the patient whose haemoglobin level rapidly decreased from 11 g/dL to 8...

Norovirus (NoV) is recognized as the most common cause of foodborne outbreaks. In 2014, an outbreak of acute gastroenteritis occurred on a cruise ship in Brazil, and NoV became the suspected etiology. Here we present the molecular identification of the NoV strains and the use of sequence analysis to determine modes of virus transmission. Food (cream cheese, tuna salad, grilled fish, orange mousse, and vegetables soup) and clinical samples were analyzed by ELISA, conventional RT-PCR, qRT-PCR, and sequencing...

Cruise tourism has become more popular. Long-term personal contact, complex population flows, a lack of medical care facilities, and defective infrastructure aboard most cruise ships is likely to result in the ship becoming an incubator for infectious diseases. In this paper, we use a cruise ship as a research scenario. Taking into consideration personal behavior, the nature and transfer route of the virus across different surfaces, virus reproduction, and disinfection, we studied contact infection of infectious disease on a cruise ship...

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...

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...
