A man in China has reportedly died after catching hantavirus. Keeping this in mind, the other 32 passengers on the bus were also tested for the virus. Hantaviruses in the America are known as "New World" hantaviruses and may cause hantavirus pulmonary syndrome (HPS). The CDC says rodent population control is the main strategy to prevent the spread of infection. Infection with any hantavirus can produce hantavirus disease in people.
According to the Centers for Disease Control and Prevention (CDC), hantavirus is mainly spread by mice and can cause various diseases in people.
Early Hantavirus symptoms include fever, fatigue and muscle aches, especially in the large muscle groups such as hips, thighs, back, and sometimes shoulders. They may also get headaches, chills and suffer from dizziness along with nausea, vomiting and diarrhoea and abdominal pain. The symptoms of HPS usually appear within 2-4 weeks of exposure but it can appear as early as 1 week or as late as 6 weeks after infection. The virus is not airborne, but can be transmitted from one person to another if someone touches their eyes, nose or mouth after touching rodents' dropping, urine or nesting materials. Due to a small number of reported cases of HPS, the incubation period of the virus isn't correctly known yet.
There is no treatment for hantavirus discovered till yet but early diagnose of the infection can prevent the patients from unsafe outcome as the patient can receive supportive care including oxygen therapy, fluid replacement, and blood pressure medications.
There is no specific treatment other than medical care and ICU, where oxygen therapy can help with respiratory distress.
If the initial symptoms of the disease are not detected and left untreated, it can lead to vascular leakage, fluid in the chest, acute kidney disease, acute shock and failure of organs. The website further said that even a healthy individual is at risk for HPS infection if exposed to the virus.
