Humans have been battling viruses since our species evolved into modern forms. For some viral diseases, vaccines and antiviral drugs have helped us stop the spread of infections and help sick people recover. For a disease - smallpox - we can eradicate it, freeing the world from new cases.
However, we cannot win the fight against the virus. Many viruses have jumped from animals to humans in recent decades, triggering a massive outbreak that has claimed tens of thousands of lives.
Some deadliest and dangerous viruses in history are as follows:
- Marburg Virus
- Ebola Virus
- Rabies Virus
- HIV Virus
- Small Pox Virus
- Hanta Virus
- Corona Virus
Marburg Virus:
Scientists discovered the Marburg virus in 1967 during a small outbreak in laboratory workers in Germany associated with infected monkeys imported from Uganda. The Marburg virus is similar to Ebola, both of which cause hemorrhagic fever, meaning that infected people have a high fever and hemorrhage throughout the body, leading to shock, failure, and death.
According to the World Health Organization (WHO), the prevalence rate was 25% in the first place, but in the Democratic Republic of Congo in 1998-2000 and in Angola in 2005, it was over 80%.
Ebola Virus:
The first known outbreak of Ebola in humans occurred simultaneously in 1976 in the Republic of Sudan and the Democratic Republic of Congo. Ebola can be transmitted through blood or other body fluids or the tissues of infected people or animals. Elke Muhlberger, an Ebola virus expert and associate professor of microbiology at Boston University, says species known to live science are changing dramatically.
One species, Ebola Restone, does not make people sick. But for the Bundibugo race, according to the WHO, the mortality rate is up to 50%, and for the Sudanese race, it is up to 71%.
Rabies Virus:
Although rabies vaccines for pets introduced in the 1920s helped make the disease rare in developed countries, the condition remains a serious problem in India and some parts of Africa.
Although very few people survive rabies, the disease usually causes death. For this reason, if you feel you have been infected with rabies, you should take several shots to prevent infection.
HIV Virus:
HIV Detects white blood cells called CD4 cells. HIV CD4 goes inside the cell and makes copies of it. Then, HIV kills CD4 cells and finds new HIV copies to enter other CD4 cells and restart the cycle. HIV Kills cells of the immune system that help the body fight infections and diseases
Powerful antiviral people drugs allow people to live with HIV for years. But the disease continues to plague many low- and middle-income countries, accounting for 95% of new HIV infections. One out of every 25 adults in the WHO African region is HIV positive, more than two-thirds of those living with HIV Virus worldwide.
Smallpox Virus:
Thousands of years ago, the variola virus (smallpox) emerged and began to cause illness and death in the human population, with a periodic spread of smallpox. Thanks to the vaccine's success, the last natural outbreak of smallpox in the United States occurred in 1949.
Today, the virus is only available in the US and two secure laboratory facilities in Russia. Smallpox, one of the most deadly diseases in history, has killed more than 300 million people since 1900 alone.
Hanta Virus:
Went. Hantavirus Pulmonary Syndrome (HPS) first gained widespread attention in the US in 1993, when a healthy Navajo teenager living in the Four Corners area of the United States and his fiance died within days of suffocation. Health officials isolated the Hantavirus from a deer rat living in an infected home a few months later. According to the Centers for Disease Control and Prevention, more than 600 people are now infected with HPS in the US, and the disease accounts for 36 percent of deaths.
The virus is not transmitted from one person to another. Instead, people can be infected by infecting the feces of infected rats.
Previously, Clinical Microbiology Reviews published in the journal 2010 that a particular hantavirus outbreak occurred during the Korean War in the early 1950s. More than 3,000 soldiers fell ill, 12% of whom died.
Although the virus was new to Western medicine, it was introduced by U.S. researchers, who later realized that Navajo medical traditions could explain a similar disease and linked the disease to rats.
Corona Virus :
On December 31, 2019, the WHO was informed of cases of pneumonia of unknown cause in the city of Wuhan, China. The novel Coronavirus was discovered by Chinese authorities on January 7, 2020, and is tentatively named "2019-nCoV".
Coronaviruses are a large family of viruses that can cause illnesses ranging from the common cold to serious illnesses such as Middle East respiratory syndrome and acute respiratory syndrome. The novel coronavirus is a new species previously unrecognized in humans.
The virus spreads from the mouth to the mouth or from the nose to small fluid cells when an infected person coughs, sneezes, speaks, sings, or breathes. These cells range from large air droplets to small aerosols.
The coronavirus killed billions of people in the world till now.
Know your risks to minimize risk. Follow these basic precautions:
- Wear your face mask
- Maintain social distance from others
- Avoid social gatherings, i.e., receptions, weddings, funerals, etc.
- Clean your hands with soap
- Use hand sanitizer every time
- Get vaccinated
