Everything About the New Hantavirus; How Dangerous Is It? + Ways of Transmission and Prevention

According to SAEDNEWS, when the coronavirus first appeared around the world, no one imagined that people would need to follow the strictest health protocols just to survive the virus.

Today, years after the difficult period of the COVID-19 pandemic, the effects of the virus can still be seen in our health. Therefore, to stay safe from dangers similar to the coronavirus, we must take even greater care of our health.

Now, reports are emerging about a dangerous and potentially deadly virus being detected on a passenger ship in international waters.

Hantavirus is not the name of a single virus, but rather a group of viruses mainly associated with infected rodents. Under certain conditions, these viruses can enter the human body through contact with rodent urine, feces, saliva, or contaminated particles left behind by rodents. Therefore, when talking about hantavirus, we are referring to a viral family that, depending on the type of virus, geographical location, and the individual’s immune condition, can cause illnesses ranging from mild to severe.

Hantavirus is not a newly discovered disease and should not be viewed like common respiratory viruses or pandemics such as COVID-19. Most types of this virus are not easily transmitted from person to person, and contact with environments contaminated by rodent secretions is usually the primary route of infection.

  • This virus can cause severe lung and kidney diseases.

  • Cases worldwide are very rare, but some strains have high mortality rates.

  • Cases have been reported in some countries in Asia and the Americas.

Ways of Transmission

  • Inhalation of particles contaminated with rodent urine, feces, or saliva

  • Direct contact with rodents

  • Rarely through rodent bites

Hantavirus is currently not considered a global pandemic.

Declaring a global emergency is the responsibility of the World Health Organization.

Disease Status in Iran

  • So far, no reports of a widespread hantavirus epidemic in Iran have been published.

  • As in other parts of the world, wherever rodents are present, there is a possibility of disease transmission cycles forming.

  • People and healthcare systems should remain alert regarding diseases transmitted between animals and humans.

  • Environmental hygiene and rodent control are the most important preventive measures.

Two Main Forms of the Disease

Hemorrhagic Fever with Renal Syndrome

  • Kidney damage

  • Low blood pressure

  • Bleeding in severe cases

  • Lower mortality rate compared to the pulmonary form

Hantavirus Pulmonary Syndrome

  • Severe lung involvement

  • Shortness of breath and respiratory failure

  • High mortality rate

Early Symptoms of the Disease

  • Sudden fever

  • Severe muscle pain

  • Nausea and vomiting

Warning Signs

  • Severe shortness of breath

  • Low blood pressure

  • Kidney problems and bleeding

Treatment

There is no specific cure, but supportive care is extremely important.

  • Hospitalization and continuous monitoring

  • Oxygen therapy and ventilators in severe cases

  • Regulation of fluids and electrolytes

  • In kidney-related cases: temporary dialysis to support kidney function

Prevention

  • Disinfect contaminated areas before cleaning

  • Use masks and gloves during cleaning

  • Control rodent populations

  • Ventilate abandoned houses before entering

  • Never touch live or dead rodents with bare hands
