What is the Ebola death rate?

Ebola virus disease (EVD), formerly known as Ebola hemorrhagic fever, is a rare but severe, often fatal illness in humans. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The average EVD case fatality rate is around 50%.

What is the leading causes of high mortality rate due to dengue?

Among the 20 patients who died after one week of hospitalization, the major causes of death were secondary infections (n = 10 [50%]), renal failure (n = 2 [10%]), and respiratory failure (n = 2 [10%]). Four (20%) patients died of severe dengue.

What is the difference between dengue and COVID-19?

Severe dengue happens when your blood vessels become damaged and leaky. And the number of clot-forming cells (platelets) in your bloodstream drops. This can lead to shock, internal bleeding, organ failure and even death. Warning signs of severe dengue fever — which is a life-threatening emergency — can develop quickly.
