Understanding Hantavirus: Risk and Prevention
Global concerns have risen as cases of hantavirus emerge on a cruise ship, prompting questions about the disease's nature and how to protect against it.
DUBAI: The recent diagnosis of several hantavirus cases onboard the MV Hondius has sparked global health concerns, reminiscent of the COVID-19 pandemic.
The World Health Organization (WHO) has confirmed eight cases and three deaths among passengers and crew.
Despite its extremely low risk for most people, understanding how hantavirus spreads and how to prevent infection is crucial.Hantaviruses are zoonotic viruses primarily carried by wild rodents, with each strain associated with a specific rodent species.
Infected rodents can carry the virus without showing symptoms but can cause severe illness in humans upon exposure to their urine, droppings, or saliva, especially in enclosed spaces.The WHO emphasizes that hantavirus does not typically spread between humans.
However, the Andes virus is an exception, capable of limited human-to-human transmission.
Dr. Jorge Salinas from Stanford Medicine explains that unlike highly contagious viruses such as flu and COVID-19, hantavirus is inefficient at person-to-person transmission.Symptoms of hantavirus appear one to eight weeks after exposure, often mimicking the flu with fever, muscle aches, and fatigue.
The disease can rapidly progress, depending on the strain.
In the Americas, it causes Hantavirus Cardiopulmonary Syndrome, leading to severe pneumonia and fluid in the lungs.
In Europe and Asia, it results in Hemorrhagic Fever with Renal Syndrome, primarily affecting the kidneys and blood vessels.As there is currently no vaccine or specific antiviral treatment for hantavirus, early supportive medical care significantly improves survival chances.
Prevention remains the best defense, achieved through rodent control measures.The outbreak on the cruise ship highlights that outbreaks can occur unpredictably.
Experts suggest this reflects a larger pattern where viruses jump from animals to humans due to climate change and human encroachment into wildlife habitats.
As a result, investing in surveillance, research, and understanding of how these viruses move through animal populations becomes vital.
