  • It is one of the top 10 causes of deaths worldwide and the world's deadliest infectious disease in

  • The past 200 years it has killed more than 1 billion people more than malaria

  • HIV and AIDS

  • influenza cholera and the plague combined in ancient Greece

  • It was called 'the isis tabbies in ancient rome and scotch up earth in ancient. Hebrew

  • It was also called the white plague and the captain of all these men of death before being given its official name

  • tuberculosis or TB for short

  • Numbers are less drastic than they used to be but still 10 million people in

  • 2017 fell ill with it and 1.6 million people died from it including

  • 230,000 children that is over 4,000 humans every day

  • TB still exists and drug resistance is a continued threat

  • So what is it? How does it work? And what is being done to combat the disease?

  • Two billion people or one quarter of the population of the world has TB in latent form

  • this means they have been infected with it, but are not ill with a disease and cannot transmit it a

  • Person infected with TB has a five to fifteen percent chance of it turning active and getting ill with it in their lifetime

  • People have a much higher risk of getting ill if they have a compromised immune system those with malnutrition

  • Diabetes or HIV for example children pregnant women and the elderly also are at a higher risk

  • So what is it TB is a disease caused by the bacteria

  • Mycobacterium tuberculosis

  • This bacterium primarily infects the lungs but it can also spread to other organs a

  • Person with active TB in their lungs can spread germs through the air when they cough sneeze or spit

  • Just a few germs are enough to infect a person

  • if you inhaled the bacteria by another person it travels down to the lungs where it will begin to multiply your

  • Body's defense system will engage engulf and transport the bacteria to lymph nodes and try to kill or neutralize the bacteria

  • Most healthy people will kill the bacteria

  • And have no symptoms afterwards if your defense system can't kill the bacteria, but contains it

  • This is when it is classed as latent if the bacteria

  • Overwhelmed the defense in the lungs and it is not contained. This will then be classed as active and you will become ill

  • Even in the latent state the bacteria are dormant and can activate and spread in months or even years later

  • Having a low immune system as mentioned before heightens the risk

  • This is especially true in young children who do not have a fully developed immune system for people with HIV

  • Typical symptoms of someone infected are a persistent cough lasting more than three weeks blood when coughing a high temperature

  • night sweats weight loss loss of appetite

  • Swelling in the neck

  • If you or anyone, you know coughs up blood or has any of these symptoms for three weeks or more

  • You should see a doctor as soon as possible

  • There are areas known as the thirty high burden areas where it is

  • most common eighty seven percent of new cases in 2017 occurred in these countries and

  • Two-thirds of these were from eight countries alone

  • These are India China Indonesia the Philippines Pakistan Nigeria Bangladesh and South Africa

  • Overall 95 percent of cases and deaths are in developing countries

  • The vast majority of TB cases can be cured when medicines are available and administered properly

  • Infants in countries with high infection rates are often given the bacillus Calmette gain vaccine or BCG

  • But generally because of underfunding many infants are not and many adults go undiagnosed with TB until it is too late

  • without proper treatment

  • 45% of people if you get TB will die and nearly all of those who are hiv-positive will die

  • Smoking also significantly increases the risk of getting infected and dying from it

  • 8% of cases worldwide are connected to smoking

  • When diagnosed the standard course of treatment is six months of four antimicrobial drugs, which is normally enough to cure the patient fully

  • From 2000 to 2017 an estimated 54 million humans were diagnosed treated and saved from TB

  • drug-resistant strains of TB are rising and in

  • 2017 approximately five hundred and fifty-eight thousand new cases with resistance to rifampicin the most effective first line drug

  • 85% of people resistant to this drug were also resistant to the common alternatives

  • There are limited resources to the second line of treatment which can require two years of chemotherapy and medicines that are expensive

  • Toxic and not always readily available

  • Many cases have even more severe resistance to drugs leaving them. No further treatment options at all

  • It is estimated that

  • 3.5 billion US dollars are needed per year to fill the resource gap for implementing even the existing TB intervention

  • research is ongoing to find new ways to treat drug-resistant TB and a few promising drugs are starting to emerge but

  • More research and development is needed

  • Some companies doing this development can be found in the description

  • Volunteers are often the frontline in helping and more are needed to diagnose and administer drugs that help save lives all over the world

  • Awareness is also important the more people know of the symptoms and how to react the higher chance of lives being saved

  • watching and sharing videos like this following and supporting charities and

  • Organizations that are on the ground helping humans overcome the deadliest infectious

  • Disease in the world and also are trying to hold individual countries governments accountable
