Small-pox
The origin of smallpox is unknown. Smallpox is thought to date back to the Egyptian Empire around the 3rd century BCE (Before Common Era), based on a smallpox-like rash found on three mummies. The earliest written description of a disease that clearly resembles smallpox appeared in China in the 4th century CE (Common Era). -
Period: 3000 BCE to
TB (Tuberculosis)
TB is highly infectious and easily spread through airborne droplets e.g. a sneeze. Luckily this is in the hidden form and is more than "likely they will never be aware" science stated at that time that patients when get aware they go into depression.
TB disease in the lungs or throat can be infectious. This means that the bacteria can be spread to other people. TB in other parts of the body, such as the kidney or spine, is usually not infectious. -

Hepatitis-treatment Vaccine
Hepatitis is inflammation of the liver tissue. Some people with hepatitis have no symptoms, whereas others develop yellow discolouration of the skin and whites of the eyes (jaundice), poor appetite, vomiting, tiredness, abdominal pain, and diarrhoea. -
Period: 900 to
Measles- treatment Vaccine
Measles is a highly contagious infectious disease caused by the measles virus. Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. Initial symptoms typically include fever, often greater than 40 °C (104 °F), cough, runny nose, and inflamed eyes. -
Hand- washing introduced
The importance of handwashing for human health – particularly for people in unsafe circumstances was first seen in the mid 19th century by two engineers of hand hygiene: the Hungarian doctor Ignaz Semmelweis who worked in Vienna, Austria and Florence Nightingale, the English "founder of modern nursing". At that time most people still believed that infections were caused by foul odours called miasmas. -

Staphylococcus- treatment methicillin
Staphylococcus is a variety of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope, they appear spherical (cocci), and form in grape-like clusters. Staphylococcus species are facultative anaerobic organisms (capable of growth both aerobically and anaerobically). -
Louis Pasteur-Germ theory of disease
The germ theory of infection is the currently accepted scientific theory for diseases. It states that microorganisms known as pathogens or "germs" can lead to disease. These small organisms, too small to see without magnification, attack humans, animals, and other living hosts. Germ may refer to not just a bacterium but to any type of microorganism or even non-living pathogens that can cause disease, and whether a possible host individual becomes infected when opened to the pathogen. -

Chicken pox
Chickenpox infection is caused by a virus. It can spread through direct contact with the rash. It can also spread when a person with the chickenpox coughs or sneezes and you inhale the air droplets.
Chickenpox is an infection caused by the varicella-zoster virus. It causes an itchy rash with small, fluid-filled blisters. Chickenpox is highly contagious to people who haven't had the disease or been vaccinated against it. -

10. Influenza (Flu)
To most people flu is a pretty unpleasant illness contracted 2-3 times in a lifetime. However, influenza was responsible for one of the most destructive pandemics of all time – the Spanish Flu (1918-1919) which killed up to 100 million people. The particular type of flu strain was unusual in that most fatalities where amongst the young and healthy. It seems that the flu actually turned the healthy body’s immune system on itself creating a “cytokine storm” which attacked the lungs. -

9. HIV/AIDS
Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) works by effectively destroying the body’s defences to any number of other diseases and infections. There is still no cure or vaccine and until very recently, no effective treatment. To date, more than 30 million people have died of AIDS with nearly 40 million currently infected.
