The Chinese “Global Times” said on Tuesday that a Chinese citizen from Yunnan Province died after being infected with the “Hanta” virus.

The death of the Chinese citizen has raised fears of a new epidemic, especially with the crisis the world is witnessing due to the outbreak of the new Corona virus.

Hanta Pulmonary Virus Syndrome is an infectious disease characterized by influenza-like symptoms that can rapidly rise to life-threatening respiratory problems.

Several types of Hanta viruses can cause the infection of the Hanta Pulmonary Virus Syndrome, and are carried by several types of rodents, especially the yarn mouse.

According to a report by the Mayo Clinic research site, one becomes infected mainly by breathing air contaminated with Hanta viruses that are secreted with the urine and feces of rodents.

Because treatment options are limited, the best protection against Hanta Syndrome virus is to avoid rodents and their location.


Lung syndrome of the Hanta virus develops in two distinct phases. In the first stage, you may have flu-like signs and symptoms, which may include:

Fever and chills.

Headaches and muscle aches.

Vomiting, diarrhea or abdominal pain.

In the early stages, it is difficult to distinguish Hanta virus infection from influenza, pneumonia or other common conditions. After four to 10 days have passed, more serious signs and symptoms begin and usually include:

Cough that results in secretions
shortness of breath
Fluid accumulated inside the lungs
Reduction of Blood pressure
Decreased heart efficiency

** When to see a doctor

The signs and symptoms of HF may get worse and may become life-threatening faster. If you are in an environment close to rodents or its droppings and have signs and symptoms of fever, chills, muscle aches, or breathing difficulties, hurry to seek medical intervention soon.

** the reasons

Each type of Hanta virus is a preferred carrier of rodent. The deer mouse is the primary carrier of the virus responsible for the majority of cases of pneumonia with Hanta virus in North America. Other carriers of the Hanta virus include the white-tail mouse, the cotton mouse and the rice mouse.

Inhalation: The main route of transmission

Hanta viruses are transmitted to people primarily through the localization of viruses present in infected rodent droppings, urine or saliva. Conservancy occurs when the virus is released into the air, making it easier for you to inhale. For example, the broom used to clean mouse droppings in the attic might push into the air small particles of feces that contain Hanta viruses, which you can then inhale easily.

After inhaling Hanta viruses, they reach your lungs and begin to invade small blood vessels called capillaries, which eventually lead to their leakage. Then your lungs are overflowing with fluid, which can cause any of the respiratory problems associated with pneumonia, Hanta virus.

Transfer from one person to another

People with North American Hanta Pulmonary Syndrome are not intended for other people. However, specific incidents of spread in South America have shown evidence of transmission from person to person, which illustrates the diversity of strains in different regions.

** Risk factors

Hanta pneumonia syndrome is most common in rural areas in the western United States during the spring and summer months. Hanta Pulmonary Syndrome also occurs in South America and Canada. Other Hanta viruses occur in Asia, causing kidney disorders instead of lung problems.

People who work, live or play in places where rodents live are more likely to get Hanta syndrome. Factors and activities that increase the risk include:

Opening and cleaning of buildings or barns unused for a long time.
House cleaning, especially in attics or other unoccupied areas.
Having a home or work space full of rodents.
Having a job involving exposure to rodents, such as construction, public works, and pest control.
Camping, hiking, or fishing.
** Complications

Hunta syndrome can quickly become life threatening. Where breathing becomes more difficult with the lungs filling with fluid. Blood pressure begins to decrease and the organs deteriorate, especially the heart. Depending on the Hanta virus strain, the death rate in the North American group due to this virus can exceed 30%.

** protection

Keeping rodents out of your home and workplace can reduce the risk of infection with the Hanta virus. Try the following tips:

Block entry areas of rodents. Mice may be able to enter the holes even if they are 1/4 inch (6 mm) small. Therefore, plug these holes with wire, metal or concrete cover.

Close the cupboard. Wash dishes immediately, clean tables and floors, and store your food – including pet food – in rodent-proof packaging. Use tight lids on rubbish bins.

Reduce nests. Dispose of herbs and trash far from home.
Set traps. Traps with springs must be installed along the wall panels. Use caution when using poisonous traps, as poison can harm people and pets as well.

** Safe cleaning procedures

Dampen dead rodents and areas where rodents were with alcohol, household antiseptics, or bleaching materials. It kills this virus and helps prevent dust carrying the infection from splattering in the air. Once everything is wet, use a wet towel to pick up contaminated materials. Then wipe or clean the area with a sponge using antiseptics.
