Read Time:3 Minute, 34 Second

As various countries around the world continues the fight the deadly pandemic, Coronavirus; a recent tweet from Global times, China reported that a  man has died in Yunnan province of China after testing positive to Hantavirus. The man died while on his way back to Shandong Province for work on a chartered bus. This prompted the Hantavirus to  immediately become a trend on social media following the report with people panicking that it was another COVID-19 ready to cause a new pandemic. However, unlike coronavirus, hantavirus is not airborne.

What is Hantavirus

What exactly is Hantavirus

According to the Centre for Disease Control and Prevention (CDC), Hantavirus is basically a family of viruses that originate from rodents or rats. Every kind of hantavirus is specific to a category of rodent.
Health officials first identified hantavirus in an outbreak in 1993 in the “Four Corners” area of the southwestern U.S.

What is the mode of transmission

The disease is transmitted from rodent droppings, urine or their saliva. Humans get infected when they breathe the air contaminated with the virus, however, the is not contagious.

Kinds of rats that cause Hantavirus

There are four kinds of rats that usually cause hantavirus — cotton rat (Sigmodon hispidus), deer mouse (Peromyscus maniculatus), rice rat (Oryzomys palustris) and white-footed mouse (Peromyscus lecopus).

How  Does this Virus Act on the Human Body

Hantaviruses are classified into two categories — ‘New World’ hantaviruses and ‘Old World’ hantaviruses. The former are known to cause Hantavirus Pulmonary Syndrome,  a severe, sometimes fatal respiratory disease whereas the latter causes Hemorrhagic Fever with Renal Syndrome, causing severe headache, fever, nausea, blurred vision along with vascular leakage and acute kidney failure and finally death.

What is the Incubation Period for Hantavirus

According to the CDC, in North America, the incubation period (time from initial exposure to the virus and development of the first symptoms) is between one to five weeks after initial exposure to infected rodent urine, droppings, or saliva. In South American outbreaks, researchers estimate that the incubation period varies from about 12-27 days.

Signs and Symptoms of the Hantavirus Pulmonary Syndrome

Due to the small number of  Hantavirus Pulmonary Syndrome cases, the “incubation time” is not positively known. However, on the basis of limited information, it appears that symptoms may develop between 1 and 8 weeks after exposure to fresh urine, droppings, or saliva of infected rodents.

Early Symptoms of Hantavirus Pulmonary Syndrome
Early symptoms include fatigue, fever and muscle aches, especially in the large muscle groups—thighs, hips, back, and sometimes shoulders. These symptoms are universal.

There may also be headaches, dizziness, chills, and abdominal problems, such as nausea, vomiting, diarrhea, and abdominal pain. About half of all Hantavirus Pulmonary Syndrome patients experience these symptoms.

Late Symptoms

Four to 10 days after the initial phase of illness, the late symptoms of Hantavirus Pulmonary Syndrome appear. These include coughing and shortness of breath, with the sensation of, as one survivor put it, a “…tight band around my chest and a pillow over my face” as the lungs fill with fluid.

Treatment of Hantavirus

In case of Hantavirus Pulmonary Syndrome, patients are put in intensive care and are given oxygen therapy to help them through the period of severe respiratory distress.
For Hemorrhagic Fever with Renal Syndrome, the treatment includes careful observation of patient’s fluid intake, electrolyte levels, blood pressure levels. Some might also require dialysis to correct severe fluid overload.

Some doctors have tried to use antiviral drugs, such as ribavirin, are used to treat other strains of hantavirus and associated infections. But, no large trials have proven them to work, but doctors may try in very severe cases.

Is it Possible to Prevent Hantavirus Pulmonary Syndrome

There are no vaccines available to protect against any types. The CDC recommends

  • Elimination  or reduction of contact with any rodents (for example, at home, worksites, campsites, barns, sheds) by reducing rodent access or rodent-proofing.
  • Sealing up gaps and holes and  placing traps.
  • keeping areas as clean and food free as possible will help.
  • If a person must come in contact with rodents or areas where they live, precautions such as gloves and masks may reduce the chances for infection; disinfectant treatment of possible contaminated surfaces may also help prevent the disease.
