Beware of Viruses Spread by Rats! Understanding Hantavirus and How to Prevent It

BeeFams, lately the term hantavirus has been gaining attention following reports of several positive and suspected cases in Indonesia, as well as international cluster cases linked to cruise ships in South America. Although considered a rare disease, hantavirus should still be taken seriously because it can affect the lungs and kidneys and may lead to serious complications if not treated promptly.

However, BeeFams, there’s no need to panic excessively. So far, the spread of hantavirus remains relatively limited and is not as easily transmitted as respiratory viruses like Covid-19. The most important thing is to understand how it spreads, maintain environmental cleanliness, and keep your immune system in good condition.

What Is Hantavirus?

Hantavirus is a group of zoonotic viruses, meaning viruses that naturally live in rodents such as rats and mice and can spread to humans. Transmission usually occurs through urine, saliva, or droppings from infected rodents.

The virus most commonly enters the body when a person inhales dust particles contaminated with rat droppings or urine, especially while cleaning areas that have been closed for a long time, such as warehouses, attics, garages, or vacant houses.

In general, hantavirus can cause two major types of illness in humans:

• Hantavirus Pulmonary Syndrome (HPS)

Affects the lungs and respiratory system. This type is commonly found in the Americas and can rapidly progress into respiratory failure.

• Hemorrhagic Fever with Renal Syndrome (HFRS)

Affects blood vessels and kidneys. This type is more commonly found in Asia and Europe, including several reported cases in Indonesia.

BeeFams, the hantavirus strain currently attracting global attention is the Andes variant found in South America. This variant is known to be more virulent and has a relatively high mortality rate. Unlike most hantaviruses, the Andes variant has also been reported to have the potential for limited human-to-human transmission through close contact over a certain period of time.

Even so, experts state that its transmission is still not easy and does not spread freely through the air like Covid-19.

What Is the Situation in Indonesia?

In Indonesia, hantavirus cases are still relatively limited, but the virus has been detected in both humans and rodents.

Several studies have also identified the presence of Seoul virus (SEOV), one of the hantavirus types commonly found in Asia. This strain is generally transmitted from rats to humans, not from human to human.

Although cases in Indonesia are generally not as severe as the Andes variant, hantavirus can still cause serious conditions, especially if not detected and treated early.

Symptoms of Hantavirus to Watch Out For

In its early stages, hantavirus symptoms often resemble common flu symptoms, causing many people to overlook them. Early symptoms may include:

• Fever
• Muscle aches
• Headache
• Fatigue
• Nausea or vomiting
• Diarrhea
• Abdominal pain

The incubation period for hantavirus is relatively long, ranging from about 1–8 weeks after exposure.

In some cases, symptoms may worsen within a few days and develop into:

• Cough
• Shortness of breath
• Chest pain
• Respiratory problems
• Kidney disorders
• Low blood pressure

In severe cases, fluid can build up in the lungs, leading to respiratory failure and shock. Therefore, BeeFams, it is important to seek medical attention immediately if these symptoms appear after exposure to rodent-infested environments or areas with signs of rat droppings.

How Does Hantavirus Spread?

Hantavirus is most commonly transmitted through:

• Inhaling air contaminated with rat urine or droppings
• Touching contaminated surfaces and then touching the face without washing hands
• Consuming contaminated food
• Bites from infected rodents

The risk of exposure is higher for people who:

• Live in areas with high rodent populations
• Clean warehouses or abandoned buildings
• Work in construction, storage facilities, or pest control
• Frequently engage in outdoor activities such as camping or hiking

6 Simple Ways to Prevent Hantavirus at Home

Since there is currently no specific vaccine for hantavirus, prevention remains the most important step.

1. Avoid Sweeping Rat Droppings While Dry

BeeFams, never directly sweep dry rat droppings because virus particles can become airborne. It is better to spray the area first with disinfectant or diluted bleach.

2. Wear Masks and Gloves

Especially when cleaning warehouses, attics, or areas that have not been used for a long time.

3. Seal Entry Points for Rodents

Check vents, ceilings, and gaps around the house that may allow rats to enter.

4. Store Food Properly

Use sealed containers to prevent food contamination from rodent urine or droppings.

5. Wash Hands Regularly

Make it a habit to wash your hands with soap after cleaning or after activities in high-risk areas.

6. Maintain a Strong Immune System

When immunity weakens, the body becomes more vulnerable to infections, including viral infections. That is why maintaining a balanced diet, getting enough sleep, exercising regularly, and managing stress are all important.

The Importance of Maintaining Immunity Amid Disease Risks

BeeFams, the recent emergence of various infectious diseases serves as a reminder that maintaining good health should not only happen when we are sick, but should become part of our daily lifestyle.

Besides keeping the environment clean and practicing healthy habits, the body also needs nutritional support to help maintain optimal immune function.
