			The primary reservoir of the Andes virus is the [[long-tailed pygmy rice rat]] (''Oligoryzomys longicaudatus''), which is found in the southern regions of South America. The virus is transmitted to humans through inhalation of aerosolized particles from rodent excreta, such as urine, droppings, or saliva. Unlike other hantaviruses, the Andes virus is also capable of human-to-human transmission, which has been documented in several outbreaks.

# Andes Virus

The **Andes virus** is a species of hantavirus, a group of viruses that are known to cause hantavirus pulmonary syndrome (HPS) in humans. It is named after the Andes mountain range in South America, where it was first identified. The virus is primarily found in Argentina and Chile, and it is unique among hantaviruses because it can be transmitted from person to person.

== Virology ==

Andes virus is an enveloped virus with a single-stranded, negative-sense RNA genome. It belongs to the family [[Hantaviridae]] and the genus [[Orthohantavirus]]. The genome of the Andes virus is segmented into three parts: the small (S), medium (M), and large (L) segments, which encode the nucleocapsid protein, glycoproteins, and RNA-dependent RNA polymerase, respectively.

== Transmission ==

The primary reservoir for the Andes virus is the long-tailed pygmy rice rat (*Oligoryzomys longicaudatus*). Humans can become infected through contact with the urine, droppings, or saliva of infected rodents, or by inhaling aerosolized particles containing the virus. Unlike other hantaviruses, Andes virus can also be transmitted from person to person, particularly in close-contact settings.

== Clinical Manifestations ==

Infection with the Andes virus can lead to hantavirus pulmonary syndrome (HPS), a severe respiratory disease characterized by:

* Fever
* Muscle aches
* Fatigue
* Shortness of breath
* Cough

The disease can progress rapidly, leading to respiratory failure and, in some cases, death. The case fatality rate for HPS caused by Andes virus is approximately 30-40%.
