Most dangerous viruses Avian influenza, Ebola, and Zika:
It seems that there is news about harmful viruses almost every day. But so far, experts say Zika itself isn’t as dangerous as HIV, Ebola, and these eight other viruses.
1. The most deadly virus is the Marburg virus.
We name it after a small, idyllic town on the River Lahn, but that has nothing to do with the disease itself. Marburg virus is a hemorrhagic fever virus. As with Ebola, the Marburg virus causes seizures and bleeding from the mucous membranes, skin, and organs. It has a 90 percent mortality rate.
2. There are five strains of the Ebola virus,
each with names of countries and regions in Africa: Zaire, Sudan, Tai Forest, Bundibugyo, and Reston. Zaire’s Ebola virus is the deadliest, with a 90 percent death rate. It is the strain that is currently spreading through Guinea, Sierra Leone and Liberia, and beyond. Scientists say flying foxes likely brought the Ebola virus from Zaire to cities.
3. Hantavirus describes various types of viruses.
I name it after a river where US soldiers were first thought to have been infected with the Hantavirus during the Korean War in 1950. Symptoms include lung disease, fever, and kidney failure.
4. The various strains of bird flu regularly cause panic,
which may be justified because the death rate is 70 percent. However, the H5N1 pressure, which is better known, has a shallow risk of contracting it. Direct contact with poultry can only infect it. They say this to explain why most cases appear in Asia, where people often live near chickens.
5. A nurse in Nigeria was the first person infected with the Lassa virus.
Rodents transmit the virus. The cases can be endemic, meaning that the virus occurs in a specific region, such as in West Africa, and can reappear there at any time. Scientists assume that 15 percent of rodents in West Africa carry the virus.

6. Junin virus is associated with Argentine hemorrhagic fever.
People infected with the virus experience tissue inflammation, sepsis, and skin bleeding. The problem is that the symptoms may seem so familiar that the disease is rarely detected or identified in the first instance.
7.The. The Crimea-Congo fever virus is infected by infection.
It is similar to the Ebola and Marburg viruses in the way it progresses. During the first days of infection, patients experience pin-sized bleeding from the face, mouth, and pharynx.
8. Machupo virus is associated with Bolivian hemorrhagic fever,
also known as black typhoid. The infection causes a high fever, accompanied by heavy bleeding. It progresses similarly to the Junin virus. The virus can be transmitted from human to human, and rodents often share it.
9. Scientists discovered the Kyasanur Forest Virus.
(KFD) in forests on the southwest coast of India in 1955. Ticks transmit it, but scientists say it is difficult to determine any carrier. Rats, birds, and wild boars are supposed to be hosts. People infected with the virus experience high fever, severe headaches, and muscle pain that can cause bleeding.
10. Dengue fever is a constant threat.
If you are planning a vacation in the tropics, find out about dengue. Mosquito-borne, dengue affects 50 to 100 million people a year in popular vacation destinations like Thailand and India. But it is more of a problem for the 2 billion people living in dengue-threatened areas.
