Ebola Replicates In Lungs, Says Research Study

Ebola studies suggest that viral replication occurred in lungs even when traces of the virus in blood samples appeared to be nil. Also, the study, observes, Ebola is one of the most contagious viruses, spreading via breathing. Therefore, patients on the recovery mode could still pass the virus accidentally to those who come in contact. Currently, scientists are investing efforts on assessing the damage caused by Ebola in lungs. The symptoms of Ebola-induced illness include high fever, bleeding, nausea and diarrhea.

These findings were discovered when levels of viral RNA fragments in the patient lungs were monitored. The viral RNA and viral replication markers sustained in the lungs for about five days after it was no longer detectable in the blood.

The earlier understanding of Ebola is that the virus causes organ failures, but no direct evidence was found that links with replication of the virus in lungs. Based on this discovery, another set of scientists have commenced studies on understanding infection and viral replication patterns in the human body.

Ebola virus causes severe hemorrhagic fever often leading to lethal illness over time. The virus is traced to wild animals in the African region and spreads through human-to-human transmission. With a fatality rate of 50%, Ebola is one of the deadliest diseases in the world. As per the World Health Organization, the first outbreak happened in the rural parts of West Africa.

The chances of survival largely depend on the level of support and symptomatic treatments provided. Currently, there are no vaccines or specialized treatments for Ebola illness. Between 2013 and 2016, over 11K people died and 28K people were infected in the west Africa. Patients who survived the illness experienced complications ranging from eye problems to musculoskeletal pains.
