You have surely heard of serious viruses such as Ebola and Zika, but many other viruses in the world are also dangerous and pose a threat to all of humanity.
Here are the most dangerous viruses in the world:
Lhasa virus
The absence of LSA symptoms is difficult to diagnose. In general, this virus infects rodents and transmits them to water, certain nutrients and human activities.
The virus first appeared in West Africa and researchers estimate that 15% of rodents living in Nigeria carry the virus.
Zika virus
The 2016 Zika virus outbreak in the world and the World Health Organization said the virus was a global problem that was threatening humanity.
In fact, the Zica virus is transmitted by mosquitoes and its infection causes congenital anomalies such as skull abnormalities and incomplete brain development (erythema).
Chikungunya virus
The virus initially appeared on four continents, in addition to the Indian Ocean and Pacific Islands, and is prone to fever and joint pain that can last for months or even years.
Nausea, headache, fatigue and rash are the main symptoms of the virus; scientists still need to find a cure.
Nippa Virus and Rift Valley Fever
The World Health Organization (WHO) said the two viruses were among the most dangerous viruses ever recorded, killing 75 percent of the virus.
The first cases of Nipah virus were recorded in pigs in 1998, before being reintroduced in India and killing at least 16 people.
The symptoms of the disease vary from respiratory problems to certain psychiatric disorders. In contrast, the Rift Valley fever appeared in Africa in 1931 and spread to humans through contaminated milk and beef.
Middle East Respiratory Syndrome and Severe Acute Respiratory Syndrome (SARS)
These viruses belong to the crown, which usually affects the upper respiratory tract and digestive tract of mammals and birds. About one third of the patients died.
Crimean-Congo haemorrhagic fever
Crimean fever first appeared on the island of Crimea in 1944 and spread to humans and cattle, with similar symptoms in 1969 in Congo. Fever causes 40% of infected people.
Despite seventy years after its appearance and the search for its causes, science has failed to find a cure for this disease. Symptoms of this type of virus include: acute headache, fever and nausea.
Ebola virus
Although this type of virus has only spread in recent years, it dates back to 1976, when Central Africa was the first affected area.
The virus causes the death of 40% of the virus and sometimes reaches 90% in some places. In fact, no vaccine against the Ebola virus has yet been found despite several clinical trials.
Marburg haemorrhagic fever
Marburg haemorrhagic fever is one of the most dangerous viruses in the world, with the Ebola virus, transmitted to humans by bats and causing the death of 90% of infected people.
