Western blotting can detect hantavirus antigen in tissue samples, [20] but is costly and time consuming. [5] Both traditional and real-time polymerase chain reaction (PCR) tests of blood, saliva, BAL fluids, and tissue samples can be used. There is a possibility of false-negatives with PCR if there are low levels of virus in the blood, and PCR ...
Western blotting can detect hantavirus antigen in tissue samples, [4] but is costly and time consuming. [12] Both traditional and real-time polymerase chain reaction (PCR) tests of blood, saliva, BAL fluids, and tissue samples can be used. There is a possibility of false-negatives with PCR if there are low levels of virus particles in the blood ...
Hantaan virus was the first hantavirus to be discovered, and the group is named after the virus. The vast majority of HFRS cases occur in China, where Hantaan virus is responsible for up to 70% of cases. Cases of HFRS caused by Hantaan virus also occur in South Korea, Russia, and Vietnam.
Detecting hantavirus infection within the first 72 hours can be challenging. Initial tests may be negative if the virus hasn't reached detectable levels. Repeat testing is often recommended after 72 hours of symptom onset. Early symptoms like fever, headache, muscle aches, nausea, and fatigue can be easily mistaken for influenza.
The loss of fluid is so severe that the density of blood cells in blood increases due to the loss of liquid (hemoconcentration). Hemoconcentration was observed in several cases and combined with the CDC's findings, a hantavirus was suspected of causing the outbreak. [8] Suspecting a hantavirus required a substantial leap of thought at the time.
Differential diagnosis often requires detailed patient history, including recent exposure to rodent habitats, which the patient may not be aware of. Point-of-care and other quick molecular diagnostic tests for hantavirus are under development, which could improve rapid diagnosis in rural areas, typically where most hantavirus cases are found.
