Bayou orthohantavirus

Bayou orthohantavirus is a virus that belongs to the Hantavirus genus within the family Hantaviridae. It is primarily found in the southeastern United States, particularly in the states of Louisiana and Texas. The virus is carried by the marsh rice rat (Oryzomys palustris), which serves as its natural reservoir.

Transmission

Bayou orthohantavirus is transmitted to humans through contact with infected rodents, particularly the marsh rice rat. This can occur through direct contact with rodent urine, feces, or saliva, or by inhaling aerosolized virus particles from rodent excreta. There is no evidence of person-to-person transmission of Bayou orthohantavirus.

Symptoms

In humans, Bayou orthohantavirus can cause Hantavirus Pulmonary Syndrome (HPS), a severe respiratory disease. Symptoms of HPS include fatigue, fever, and muscle aches, followed by shortness of breath and coughing as the disease progresses. The disease can be fatal.

Treatment

There is no specific treatment, cure, or vaccine for HPS caused by Bayou orthohantavirus. Patients often require hospitalization, intensive care, and oxygen therapy. Early recognition and medical attention can significantly improve the chances of recovery.

Prevention

Prevention of Bayou orthohantavirus infection primarily involves avoiding contact with rodents and taking precautions when cleaning areas where rodents have been present. This includes wearing gloves and masks, and disinfecting the area with bleach or other disinfectants.
