On the afternoon of March 22, regarding the Marburg virus that the world has just warned about, Dr. Phung Manh Thang, Department of Infection Control, Cho Ray Hospital, informed that this is a type of RNA virus belonging to the Filovirus family, causing hemorrhagic fever similar to Ebola.
The Marburg virus was first recognized in 1967, when outbreaks of hemorrhagic fever occurred simultaneously in laboratories in Marburg and Frankfurt, Germany, as well as in Belgrade, Yugoslavia (now Serbia).
From January 7 to February 21, 9 suspected cases of Marburg virus infection were recorded in Equatorial Guinea (West Africa), of which 1 case was confirmed by testing. All infected cases died.
According to Cho Ray Hospital's warning, the Marburg virus can be transmitted from animals to humans, from humans to humans through direct contact with body fluids of infected animals, and from humans to humans through direct contact with blood and secretions of sick people or surfaces contaminated with pathogens.
The incubation period ranges from 2 to 21 days, beginning with high fever, chills, severe headache, muscle pain. About the fifth day after the onset of the disease, a maculopapular rash may appear, most prominent on the chest, back, abdomen, symptoms of nausea, vomiting, chest pain, sore throat, abdominal pain and diarrhea may appear.
These symptoms become increasingly severe and may include jaundice, pancreatitis, severe weight loss, delirium, shock, liver failure, massive bleeding, and multiple organ dysfunction. Clinical diagnosis is difficult because the disease has symptoms similar to other infectious diseases (malaria, typhoid, Ebola hemorrhagic fever, etc.). The disease has a high mortality rate (recorded in previous outbreaks is 24%-88%).
Dr. Phung Manh Thang recommends that hospitals need to take measures to detect early cases entering Vietnam through exploiting epidemiological history and clinical symptoms. In case of detecting an infection, immediately quarantine the patient.
