Alarm sounds: The "invisible killer" on the polar cruise ship

On May 11, 2026, the World Health Organization issued an urgent notification: the number of Hantavirus cases on the polar expedition cruise ship "Hundius" had risen to nine, with three fatalities . The most recently confirmed case was a French female passenger who tested positive after disembarking and returning to France. Even more worryingly, an American passenger tested weakly positive for Hantavirus, and another has already shown mild symptoms.

WHO Director-General Tedros Adhanom Ghebreyesus has issued a clear directive: all disembarking passengers must undergo a 42-day quarantine and health monitoring period. To date, 94 passengers have returned to eight countries on seven flights.

On May 12, the Chinese Embassy in the Netherlands issued an urgent reminder: The Andean virus involved in this outbreak is a member of the Hantavirus family. In previous cases, it has shown limited human-to-human transmission, usually through close contact in enclosed spaces for extended periods.

This is not a distant story; it is a reality that is happening right now.

 Hantavirus: Closer than you think

Many people believe that the Hantavirus only exists in the wilderness of the Americas and has nothing to do with them. This is completely wrong.

The Chinese Center for Disease Control and Prevention clearly states that although there is no natural host or infection case of Andean virus in China, other types of Hantavirus exist domestically , mainly causing hemorrhagic fever with renal syndrome (i.e., epidemic hemorrhagic fever), which is more common in rural areas and urban-rural fringe areas, with approximately 200,000 infections worldwide each year.

The three main transmission routes of Hantavirus, each deadly:

The most frightening one is the first one – aerosol transmission.

Do you think that simply dry-sweeping away rat droppings is enough? Quite the opposite! Dry sweeping and vacuuming will release virus-containing aerosols into the air, and infection can occur instantly if inhaled. The correct procedure is to first wear a mask and gloves, and then spray the area with a chlorine-based disinfectant before cleaning.

Ultraviolet disinfection is the ultimate weapon against pathogens in aerosols —UV-C ultraviolet light with a wavelength of 253.7nm can destroy the molecular structure of microbial DNA and RNA within seconds, causing them to lose their ability to replicate. It has a highly effective killing effect on most pathogens, including Hantavirus , and is a purely physical disinfection with zero chemical residue and zero secondary pollution.

LIGHTBEST: The "Heart" of Ultraviolet Disinfection in China

With public health awareness at an all-time high, what you need is not an ordinary lamp, but a professional disinfection system that has been certified to national standards and exported to hundreds of countries around the world .

LIGHTBEST , as a key drafting unit for several national standards and industry group standards, including the national standard GB/T 19258.2 "Ultraviolet Germicidal Lamps", has products that have passed all the world's top certifications such as CE, UL, EPA, UKCA, RoHS, FCC, and EPR , making it an undisputed technical benchmark in the field of ultraviolet disinfection.

LIGHTBEST doesn't just sell light tubes; it provides core components and full-scenario solutions for all kinds of ultraviolet disinfection systems —from 8W to 60W, from desktop to mobile, from home to medical use, covering all power levels and providing everything you need in one place.

A powerful product portfolio: From desktop to whole-house security, Guangtai provides you with layered protection.

一、 LIGHTBEST UV Light Stand – Intelligent Lifting, Remote Timer, Full Scene Coverage

This is not a lamp; it is a disinfection robot that can think .

Remote control available – wireless remote control that goes through walls, allowing for flexible operation. Disinfection can be activated from the next room, with zero risk of exposure.

Automatic height adjustment – the lamp arm height is freely adjustable, covering different spaces from desktop to ceiling, and it is easy to store without taking up much space.

Timerable – set to any time from 10 to 120 minutes, automatically shutting off at the designated time, providing unmanned intelligent disinfection that balances safety and efficiency.

LIGHTBEST standard fluorescent tube models across all power ranges :

�� Technical Highlights : The LIGHTBEST electronic ballast features instant start or delayed start modes , intelligently matching the lamp type to reduce current surges and extend the UV lamp's lifespan by over 30% . The lamps are made of high-purity quartz with a hydroxyl (-OH) content of less than 3 ppm, resulting in extremely high UV transmittance. Ozone-free lamps concentrate 95% of their energy in the 254nm sterilization band, while ozone-containing lamps simultaneously release 185nm + 254nm dual sterilization.

II. LIGHTBEST 38W UV Germicidal Desk Lamp – An "Invisible Guardian" for Home Disinfection

Don't underestimate this desk lamp; it's a 24-hour health guardian for your bedroom, living room, and children's room.

38W high power – Employs a high-efficiency, low-pressure mercury vapor discharge lamp to generate 253.7nm UV-C short-wave ultraviolet light, with a lamp life exceeding 8000 hours.

Wireless through-wall remote control – remote control distance within 30 meters, 1-minute delay to start, automatically shuts off after a set time (15/30/60 minutes), and is completely protected from direct UV exposure during operation.

 Purely physical disinfection, ozone-free design —it will not cause secondary pollution, and is safe to use in homes with elderly people, children, and pets.

 Metal casing with anti-oxidation paint finish – a high-end matte texture, making it a work of art in your home.

 Special reminder : People over 65 years old are a high-risk group for Hantavirus infection! Keeping a germicidal table lamp at home and regularly disinfecting the living room and bedroom is the most practical way to protect your parents' health.

III. LIGHTBEST 60W Portable Ultraviolet Sterilization and Disinfection Vehicle – A Medical-Grade "Disinfection Aircraft Carrier"

When disinfection needs to cover an entire ward, an entire office building, or an entire laboratory— you need a mobile "ultraviolet fortress."

60W high-power lamp tube – ultraviolet radiation illuminance ≥70μW/cm² at 1 meter (compliant with the new national standard GB 28235-2024, which will be implemented on July 1, 2026), and sterilization irradiation intensity can reach 1600μW~3000μW.

Portable design – omnidirectional wheel chassis + adjustable light arm, from the ICU to general wards, from the laboratory to the food processing plant, it can be pushed wherever it is needed for disinfection.

Multiple safety protections – timer and remote control provide dual protection for better human health.

Meets the new national standard GB 28235-2024 —log kill value for poliovirus ≥4.0, log kill value for Staphylococcus aureus ≥5.0, electrical safety complies with GB 4706.1 and GB 4706.75, and leakage current ≤0.5mA.

�� Application scenarios : hospital infection control, school classroom disinfection, cold chain storage sterilization, food processing workshop purification, poultry farm epidemic prevention... One vehicle can handle all scenarios.

��The three possible outcomes of Hantavirus depend on your choices today.

currently no specific treatment for hantavirus ; treatment relies entirely on symptomatic support and the body's own immune system. In other words, the best medicine is to avoid infection in the first place.
