Top 10 Most Leading Causes Of Death In The World | Wit Biology

                              DEADLIEST DISEASES


        Have you ever wondered what are the deadliest diseases ever. Well I've constructed the top 10 list of the deadliest diseases of all time. 

        What do you think is the deadliest disease of all time let's get right into it.


10.TUBERCULOSIS 

       Tuberculosis also called TB. This is a bacteria that typically attacks the lungs this bacteria can also affect your brain your spine and your kidney. Tuberculosis is fatal and is widespread one-third of the world's population has been affected by this in fact there's new infections occurring in about 1% of the population each year. In 2007 there's an estimated 13.7 million people who had the bacteria in 2013. There was 9 million new cases and about 1.5 million associated deaths. 


9.SARS

        Moving on to the number nine spot. We're talking about SARS the long form of SARS is severe acute respiratory syndrome. But for short and simplicity let's call it SARS this is a viral respiratory illness caused by a corona virus.

  

       SARS was first reported in Asia back in 2003 and over the next few months. The disease spread to more than two dozen other countries SARS is spread through close person-to-person contact there were 8098 confirmed cases of SARS from November 2002. All the way to July 2003 with 774 deaths there's currently no cure for SARS but research to find the vaccine is ongoing. 


8.MEASLES

        Alright now we have at the number 8 spot we're talking measles. Measles is a highly contagious respiratory disease. This is a deadly disease. Because it's airborne the vaccine for this has become available since 2005. But will forward this there has been an estimated 2.6 million deaths each year. But recently back in 2003, 84% of children worldwide received one dose of the measles vaccine and this was all by the first birthday and this is through the health services. 

        Since this vaccine it's helped prevented 15.6 million deaths this was developed by Maurice Hilleman. He was an American microbiologist who specialized in vaccines his developed over 36 of them including mumps, hepatitis A and B, chickenpox, meningitis and ammonia and that's just the name of whew he's also been credited for saving the most amount of lives than any other medical scientist in the 20th century.


7.YELLOW FEVER

       Now coming in at number 7 we're talking about yellow fever. This is also known as yellow jack or the yellow play. Yellow fevers transmitted to humans via bites by mosquitoes oh this is easy mostly occurs in South America or Africa it's estimated 200,000 new cases every single year with 30,000 people losing their lives nearly 1 billion people live in these areas where it's very common. Now that is a very scary statistic what beats yellow fever. 


6.HIV  

       Well coming in at the number 6 spot we're talking about HIV also known as human immune over or for simplicity again let's just call it HIV. This attacks the white blood cells in your body which helps your body to fight disease. 

  

       This disease can be managed but aged the final stage of the infection has claimed the lives of more than 39 million people one of the most famous big athletes to ever first have this with Magic Johnson in the NBA and it was so scary that he stopped playing ball, because he didn't want to get in contact with other people this was so new it was such a mystery to what it was so HIV is transmitted through the exchange of bodily fluids.  

       There's 35 million people in the world right now currently living with HIV or AIDS and get this one in seven people are living with the HIV that they had no idea that they have that is so crazy. 


5.MALARIA

      Let's move on to number five malaria. Malaria is a life-threatening disease caused by parasites and these are transmitted through people by mosquitoes. I think we're learning that mosquitoes are really bad. 

      Malaria is preventable and terrible however without treatment it can be fatal about 3.2 billion people which is about half the population of the world or at risk of malaria back in 2013, 198 million people has had it and there's been 584,000 people who have died people living in the poorest countries are the most vulnerable to this 90% of malaria deaths have occurred in Africa and most of these deaths are children under five years old. 


4.EBOLA

        We are almost at the number one spot. But coming in at number four we have the most recent scare Ebola. Ebola first appear 1976. Where there was an outbreak in ZAR, which is in Africa this deadly disease got its name from the Ebola River in which it first appeared near the fatal rate for this disease is 90%. 

  

      The virus is transmitted from person to person via direct contact with bodily fluids symptoms include muscle weakness and pain and you have high fever you start heating up very quickly there has been 8460 a people who has lost their lives and this is in the countries with the widespread transmission there has been one case of Ebola in the UK and it was 39 year old Pauline cafard. She was diagnosed in December of 2014 and this was after she came back after volunteering and Sri Leone in Africa small pox 500 million people have died in the 20th century. This is so fatal. 


3.SMALL POX

      So I'm talking about 1901 all the way to 2000 smallpox was greatly feared fears of a fatal rate of 30 to 35% there's been physical evidence of this from a mummy and this is the mummy of a pharaoh who ruled in Egypt the last natural occurring case happened in Somalia in 1977. 

      There's no cure for it but there was a vaccine to prevent it which means as soon as everyone has a vaccine no one's gonna have it smallpox is not going to be in existence again. 


2.1918 FLU PANDEMIC

       Coming in at number 2 I'm talking about the 1918 flu pandemic. The 1918 flu pandemic was an unusual deadly influenza pandemic that involves the h1n1 influenza virus. The deadly flu virus attacked more than one-third of the world's population and within months it had killed more than 50 people.

  

       The 1918 flu pandemic almost took the human race for the 50 million people that died, this is the most amount of people in the quickest amount of time ever in history. The global mortality rate from 1918 to 1919 pandemic is unknown, but an estimated 10 to 20% of those people who were infected died. So this is why the total can range from about 50 million all the way up to a 100 million people.


1.THE BLACK DEATH

       So now we have come to the most deadliest disease of all time, it was very scary but I'm talking about the plague. The plague is also referred to as the Black Death it was one of the most devastating pandemics in human history. 

       When it was at its most violent in the Middle Ages it killed off 60% of London's and that's 50% of Paris and 40% of Egypt's population which is approximately 75-100 million people bodies were piled up inside and outside of city walls and this is until a massive graves can be dug there was just nowhere to put these bodies or so many and because of this contributed to the bad air. Which helps to spread and grow this disease.


       So there you have it that was the top ten most deadliest disease of all time were you surprised by any of these or what disease do you think should have made it. I really hope you learned a thing or two. Thank you so much for reading.
