Officials say a rare strain of hantavirus has been found on board a cruise ship, raising it to an international health crisis due to the confirmed presence of the Andes strain, which can spread to humans. Health officials are now tracing close contacts, and warning that the risk to the general public is low.
What is the reason for the incident on the cruise ship?
The outbreak of hantavirus in a cruise ship with approximately 150 people on board has been confirmed by health authorities, including the World Health Organization (WHO).
So far in the key developments:
- There have been at least two confirmed and a number of suspected infections reported in the laboratory.
- Multiple deaths and serious cases have occurred on board because of the outbreak.
- Investigators suspect that the first infections could have happened prior to boarding the ship.
- The ship is under tight containment and monitoring conditions.
WHO updates say contact tracing is being conducted in several countries as passengers disembarked at several ports.
So why, is this particular hantavirus strain different?
The transmission of hantavirus typically occurs through the droppings, urine or saliva of rodents and is rarely spread person-to-person.
This outbreak is a rare one, however, because it is the Andes strain.
The peculiarity of the Andes strain is:
- It is the only known human-to-human transmitted variant of hantavirus that is known.
- Close and extended contact is a primary way of spreading.
- Risk is greater in enclosed areas like shared cabins or living quarters.
However, experts on health believe it’s still rare and restricted even with this strain.
Has there been a confirmed case of human-to-human spread?
As of yet, there is no widespread description of transmission, but a critical possibility has been acknowledged.
WHO position:
- There is some evidence of possible spread from person to person to close contacts.
- Possible scenarios are when family members or cabin mates share a confined area.
- Investigations continue to determine if there are transmission chains
Meanwhile, WHO has repeatedly emphasized that there is minimal risk to the public.
What are the symptoms of hantavirus?
Hantavirus infection can be unexpected and can be quite serious.
Early symptoms include:
- Fever
- Fatigue
- Muscle aches
- Headache
Later symptoms may include:
- Cough
- Shortness of breath
- This can cause lung congestion.
- Severe respiratory distress
If left untreated, severe cases may be life threatening.
Why do cruise ship outbreaks cause concern?Why are outbreaks of concern on cruise ships?
Cruise ships are under close surveillance in cases of infectious diseases due to:
- High-density living conditions
- Areas of shared ventilation and enclosed spaces
- Regular overseas flights.
- Close passenger interactions
In certain situations, these conditions can increase the risk of spread of diseases that are transmitted through direct contact and/or air transmission of particles.
Responsiveness of the authorities
International and regional health organisations are helping with containment.
Key measures include:
- Isolation of symptomatic passengers
- For severe cases, medical evacuation was carried out.
- Testing and sanitation procedures for on-board purposes.
- Multi-national contact tracing between countries
- Passenger monitoring of disembarkation.
Worryingly, authorities have been stressing containment and not panic as the number of people who can be affected is limited.
How will this affect the public?
Although the outbreak is alarming, there are several important points stressed by experts:
- In the majority of cases, hantavirus is not easily transmitted between people
- Even the Andes strain, which requires very close and prolonged contact, is a dangerous one.
- The general public at present level of risk
What is Hantavirus and What is an outbreak of Hantavirus?
2. Is there a danger of hantavirus being spread easily among people?
No. Human-to-human transmission is very unusual, and is primarily associated with the Andes strain in close contact transmission.
2. What is the typical route of infection?
The infections usually happen when one comes into contact with the urine, droppings or saliva of rodents, not humans.
3. Is a travel warning warranted?
Health officials say the public is not at risk, and it’s not known if there’s been widespread community spread.
4. Do people get cured or a vaccine exist?
No antiviral cure or universal vaccine is currently available to treat the infection and treatment is based on supportive medical care.
