The World Health Organization says three people have died after an outbreak of a hantavirus on a cruise ship in the Atlantic Ocean. At least six people are believed to have been infected: one case has been confirmed by laboratory testing and five others are considered suspected infections. One patient is receiving intensive care in South Africa, the WHO reported.
The agency said investigations are continuing, including additional laboratory testing, epidemiological inquiries and sequencing of the virus. Medical treatment and support are being provided to passengers and crew. The WHO is helping coordinate with member states and the ship’s operators to evacuate two passengers showing symptoms and to carry out a full public health risk assessment and to support those remaining on board. The organization did not identify the vessel or provide further details.
Hantaviruses are a group of viruses typically transmitted when people come into contact with urine, droppings or saliva from infected rodents such as mice or rats. Infections are uncommon but can lead to hantavirus pulmonary syndrome, a serious respiratory condition.
Early signs often include fatigue, fever and muscle aches, and may be accompanied by headache, dizziness, chills and gastrointestinal symptoms such as nausea, vomiting, diarrhea and abdominal pain. In severe cases the illness can progress to coughing, shortness of breath and chest tightness as fluid accumulates in the lungs. According to the U.S. Centers for Disease Control and Prevention, more than one-third of patients who develop the respiratory form of the disease may die.
The disease has drawn renewed attention recently after the death of Betsy Arakawa, the wife of actor Gene Hackman.
