Hantavirus in BC: What Chilliwack Residents Actually Need to Know

What happened — the short version

In April 2026, passengers aboard the MV Hondius, a cruise ship

that had sailed from Argentina, began developing serious illness.

The cause was identified as the Andes strain of hantavirus — a

rare respiratory illness transmitted primarily through rodents,

and in rare cases, through close prolonged contact between people.

As of May 12, 2026:

• 3 people have died from the outbreak internationally
• 7 confirmed cases have been reported to the WHO, with 2

additional probable cases under investigation

• 4 Canadians from the ship landed in BC on Sunday and are

now isolating on Vancouver Island for a minimum of 21 days

• All four Canadians are asymptomatic

The ship has docked in Tenerife, Spain. All remaining passengers

have been repatriated to their home countries.

Should people in Chilliwack or BC be worried?

The short answer: no — but it is reasonable to want to understand why.

BC Provincial Health Officer Dr. Bonnie Henry was direct on Monday:

this outbreak is a "very different scenario" from COVID-19. Hantavirus

does not spread the way influenza, measles, or coronavirus does. It

does not shed easily through talking, sneezing, or coughing. Spread

requires close, prolonged contact with someone who is actively sick.

The Public Health Agency of Canada's assessment, consistent with

the WHO, is that the overall risk to the general population in Canada

from this outbreak remains low, and onward spread within Canada

is not expected.

The four BC isolates have no known direct contact with any confirmed

case. They are being monitored daily by public health teams.

What is hantavirus — and is there a BC strain?

This is an important distinction that is getting lost in coverage.

The Andes virus strain on the MV Hondius is not the same strain

found in BC. BC does have its own hantavirus strain — the Sin Nombre

virus — but it is transmitted exclusively through contact with infected

rodent droppings or urine, not between people.

The Andes strain, found in South America, is the only known hantavirus

strain capable of limited human-to-human transmission — and even then,

only in cases of close, sustained contact with a symptomatic person.

Symptoms of hantavirus typically appear 1 to 8 weeks after exposure

and include:

• Fever, chills, and muscle aches
• Nausea, vomiting, or abdominal pain
• Followed in severe cases by rapid respiratory decline

There is no specific antiviral treatment for hantavirus. Supportive

hospital care — managing fluid levels and supporting breathing — is the

primary approach for severe cases.

What this means practically for BC residents

If you were not on the MV Hondius and have not had close, prolonged

contact with a confirmed case, your risk is effectively zero.

Public health authorities are not recommending any precautions for

the general BC population beyond normal awareness.

If you have concerns about any symptoms — fever, unexplained muscle

aches, or breathing difficulty — the right first step is calling

8-1-1 (HealthLink BC) or visiting your pharmacist before heading

to an emergency room.

makes people more likely to self-diagnose incorrectly, take

unnecessary medications, or avoid care they actually need.
