Hantaviridae

Hantaviridae is a family of viruses that can cause illness in humans. These viruses are carried by rodents, such as mice and rats, and are transmitted to people through contact with rodent excreta, including urine, feces, and saliva. The viruses are not typically spread from person to person, though rare exceptions have been reported.

Infection with hantaviruses can lead to two main types of diseases. Hantavirus Pulmonary Syndrome (HPS) is characterized by respiratory symptoms, often starting with flu-like illness and progressing to severe breathing difficulties. Hemorrhagic Fever with Renal Syndrome (HFRS) is another disease caused by certain hantaviruses, which can affect the kidneys and lead to bleeding. The severity of illness varies widely, and some infected individuals may have no symptoms at all.

There are many different types of hantaviruses, each associated with specific rodent hosts and geographical regions. Prevention of hantavirus infection primarily involves avoiding contact with rodents and their droppings, especially in enclosed spaces. This includes proper cleaning and ventilation of areas where rodents may be present.

Diagnosis of hantavirus infection is typically made through laboratory tests that detect antibodies or viral genetic material in a person's blood or tissue. Treatment is supportive, focusing on managing symptoms and complications, as there is no specific antiviral medication for hantavirus infections. Early recognition and medical care can improve outcomes.
