5 Deadliest Viruses in the World
The human body has evolved over the course of thousands of years to combat deadly viruses and diseases. Plus, modern medicine has led to the development of different antiviral drugs and vaccines that help keep infections at bay and cure sick people. But even though we’ve won the battle, the war is far from over. There are still some deadly diseases out there that are capable of killing anyone that is infected, representing a growing threat. Take a look at the five of them below:
#1 Marburg Virus
This is a re-emerging pathogen which threatens human health significantly. This virus occurs naturally and leads to a fulminating hemorrhagic condition – known as the Marburg hemorrhagic fever – followed by severe shock syndrome. The result is high mortality.
The fatality rate for this disease is 90 percent. But even if you manage to survive, you still have to live with constant convalescence which is indicated by muscle weakness, hepatitis, ocular problems, arthralgia, myalgia, and even psychosis.
Marburg Virus Symptoms
The first symptoms of this fever are detected when a person suddenly contracts severe headache, myalgia, fever, and chills. The virus causes severe hemorrhaging in various parts of the body within a span of 5 to 7 days after the symptoms show up. Patients exhibit bleeding from the eyes, nose and gums, while a lot of blood in vomit or stool is a sign of gastrointestinal hemorrhage. Some people also report dehydration.
The diagnosis of Marburg hemorrhagic fever is difficult because many of the symptoms and signs resemble those of other common infectious diseases, like malaria and typhoid fever. Thus, the only way to accurately detect this virus is through microbiological methods like lgM-capture ELISA, polymerase chain reaction, and antigen-capture ELISA.
When it comes to treatment, there aren’t any options for the therapy of patients. Thus, the only available treatment is supportive, including supplemental oxygen, the maintenance of blood pressure and circulatory volume, balancing the patient’s electrolytes and fluids, and treating any other infections that might cause more complications.
