New Delhi: The coronavirus pandemic has taken over the world by storm for quite some time now. The novel virus, which first emerged in December 2019 in China’s Wuhan, has claimed over one million lives worldwide.
The coronavirus disease(Covid-19 ) is the very first pandemic of the 21st century but this is not the first time when the human race has suffered such tragic outbreak of a disease which left hundreds of thousand dead.
While scientists have been successful in finding cures of these diseases, the viruses that caused the infection are still very much prevalent even today.
Ebola outbreak emerged between 2013-2016 in West Africa. The virus infected around 28,610 people while 11,300 lost their lives to the virus. Guinea was the epicentre of the virus which later widespread in Liberia, Syria and Leona.
The Ebola virus is transmitted via blood, vomiting and diarrhea. Its symptom are relevant for 21 days but a successful vaccine has evidently contained its spread.
Human Immuno Deficiency Virus, commonly known as HIV, was first acknowledged in 1981. Since then, it has claimed over 35 million lives worldwide. According to World health Organization(WHO), the virus has affected more than 7 million people in South Africa.
HIV eliminates white cells that play a key role in the immune system. This disease destroys immunity, due to which other diseases also arise in the body. The virus can be transmitted via unprotected sex, the blood of the infected and from the infected mother to the unborn child.
Savior Respiratory Syndrome (SARS) first originated in Asia and Canada and spread in the years 2002–2003. It affected 37 countries and has fever, body pain, pneumonia as major symptoms. The virus was controlled in 2003 and no case has been reported from there till now. Scientists fear that this virus may live in animals and may give rise to diseases in the future.
Hepatitis killed over 1.32 million people worldwide in 2015. According to WHO, the death toll now has increased by 22 percent. There are five types of hepatitis including Hepatitis A, D, E but B and C have caused the most number of deaths.
It is estimated that 4.4 percent of people in the world are still infected with viral hepatitis. However, people do not get treatment even after the vaccine is available for Hepatitis B while antiviral is available for Hepatitis C.
