The deadliest virus in history is one that is currently causing a global pandemic. The virus is called SARS-CoV-2, and it causes the disease known as COVID-19. As of June 2019, the virus has caused over 400,000 deaths worldwide.

Viruses are tiny infectious agents that can replicate only inside the living cells of other organisms. The vast majority of viruses cause little or no harm to their hosts, but some viruses can be deadly.
The 1918 influenza pandemic, also known as the Spanish Flu, was the most deadly pandemic in history. It is estimated that between 50 and 100 million people were killed by the virus, which infected an estimated 500 million people worldwide – around one-third of the world’s population at the time.
The Spanish Flu was first identified in Spain in early 1918, and within months had spread around the world. The pandemic was fed by the mobility of people during World War One, as well as the overcrowding and poor hygiene conditions in military camps and hospitals. The virus was particularly deadly for young adults, who made up a large proportion of the casualties.
Other deadly viruses include Smallpox, which is estimated to have killed around 300 million people in the 20th century before it was finally eradicated in 1979; HIV/AIDS, which has claimed the lives of more than 35 million people since it emerged in the early 1980s; and Ebola, which has caused several devastating outbreaks since its discovery in 1976.
A brief history of the deadliest viruses
Viruses have been around for centuries, and they have caused illnesses ranging from the common cold to Ebola. Some viruses are more deadly than others, and some have killed more people than others. In this article, we will take a look at the deadliest viruses in history.
The Spanish Flu
The Spanish Flu was a global outbreak of avian influenza that occurred from 1918-1920. This virus was first observed in Europe, particularly in Spain, and later spread to other parts of the world through travel and military personnel. The Spanish Flu pandemic resulted in the death of approximately 50 million people, making it one of the deadliest pandemics in human history. The virus is believed to have originated from birds, and is thought to have mutated into a form that was able to infect humans. Symptoms of the Spanish Flu included fever, coughing, and difficulty breathing; most victims died within days of becoming infected. There is no known cure or prevention for this virus, and it remains a threat to public health today.
The human immunodeficiency virus, or HIV, is a virus that attacks the body’s immune system. The immune system is what helps the body fight off infection and disease.
HIV is a sexually transmitted infection (STI). This means it can be passed from one person to another through sexual contact. It can also be passed from a pregnant woman to her child during pregnancy or childbirth, and through sharing needles or syringes contaminated with HIV-infected blood.
Once HIV enters the body, it begins to destroy a type of white blood cell called a T helper cell, which is part of the immune system. As the virus continues to multiply and destroy more T cells, it weakens the immune system’s ability to fight off other infections and diseases. This increased vulnerability to infection and disease is what leads to AIDS.
There is no cure for AIDS, but there are treatments available that can prolong a person’s life. With early diagnosis and treatment, people with AIDS can now live much longer and healthier lives than they could in the early days of the epidemic.
Ebola is a deadly virus that causes fever, body aches, and diarrhea, and sometimes bleeding from the eyes, ears, and nose. The virus is named after the Ebola River in Africa, where it was first identified in 1976. Ebola is believed to cause severe illness in humans because it attacks the body’s immune system and damages the liver and kidneys.
There is no cure for Ebola, and the only treatment is to provide supportive care to patients, which can help them recover from the disease. However, Ebola can be deadly if not treated quickly. In fact, Ebola has a fatality rate of up to 90%.
Ebola is most commonly found in Africa, where it has caused several outbreaks over the years. The most recent outbreak occurred in West Africa between 2014 and 2016, and was the deadliest outbreak of Ebola in history. More than 28,000 people were infected with the virus, and more than 11,000 people died.
The current deadliest virus
The deadliest virus in history is the one that is currently raging across the globe. As of right now, that would be the coronavirus. It is a new virus, and we do not have a lot of information about it. What we do know is that it is highly contagious and is causing a lot of death and destruction.
Coronaviruses are a type of virus. There are many different kinds, and some cause disease. A newly identified coronavirus, SARS-CoV-2, has caused a worldwide pandemic of respiratory illness, called COVID-19.
Coronaviruses are spread through contact with respiratory secretions, such as saliva, mucus, or blood, from an infected person. They can also be spread through contact with objects or surfaces that have been contaminated with the virus. Inhaling airborne droplets from an infected person can also cause infection.
Symptoms of coronavirus infection include fever, cough, and shortness of breath. In severe cases, the virus can lead to pneumonia, severe acute respiratory syndrome (SARS), kidney failure, and even death.
There is no specific treatment for coronavirus infection. Treatment focuses on relieving symptoms and supporting the respiratory system.
Prevention of coronavirus infection includes washing hands regularly with soap and water for at least 20 seconds; avoiding close contact with people who are sick; avoiding touching your eyes, nose, and mouth with unwashed hands; and disinfecting surfaces that are frequently touched
The deadliest virus in history is the Ebola virus. The Ebola virus is a viral hemorrhagic fever that is fatal in humans. The virus is transmitted through contact with the blood or bodily fluids of an infected person. The virus can also be transmitted through contact with infected animals, such as monkeys, gorillas, and chimpanzees. The Ebola virus has caused dozens of outbreaks in Africa since it was first identified in 1976.
