How do we STOP these deadly pathogens/contagions?

________________ are the scientists who track the spread of disease. Remember.. ________________ are the scientists who track the spread of disease. you should already have this…

EPIDEMIOLOGISTS are the scientists who track the spread of disease. Remember.. EPIDEMIOLOGISTS are the scientists who track the spread of disease. you should already have this…

Let’s see how this works…

Epidemiologists TRACK THE SPREAD…. Should your parents be more worried for you or your younger brother or sister about Meningitis?

Epidemiologists TRACK THE SPREAD…. Should your parents be more worried for you or your younger brother or sister about Meningitis?

Epidemiologists track WHERE the disease is spreading… If you could travel to either the midwest or northeast, but didn’t want to get Lyme Disease, where would you be safer going?

Compare ARMY personnel to the PUBLIC for bacterial meningitis: Do ARMY soldiers get meningitis before or after the PUBLIC?

they work hard to stop a local outbreak (LIKE SCHOOLWIDE) from becoming an epidemic (city or country wide) to worldwide pandemic!

How do we stop these pathogens?

A hundred years ago, we hardly knew germs existed. like these pathogenic yeasts!

A hundred years ago, we hardly knew germs existed. We barely had microscopes.

A hundred years ago, we hardly knew germs existed. We barely had microscopes. What’s a microscope?

If people got sick, most people just figured they deserved it. This is an early 20th century EXORCISM kit for making people better.

or it was IN THE STARS…

But it took 30 years for the rest of the world to see the truth. Louis Pasteur saw colonies of microbes in spoiled food.

But it took 30 years for the rest of the world to see the truth. Louis Pasteur applied high heat (not boiling) to kill microbes. done to keep milk, juice, & cheese from spoiling.

Pasteur showed us HIGH HEAT (not boiling) can destroy most deadly germs in our food.

What ELSE can kill possible deadly microbes?

Ignaz Semmelweis went crazy telling doctors to wash their hands before touching the pregnant women!

but our WAR against pathogens really began in the 1920’s

It began BY ACCIDENT with Penicillin… Scottish ALEXANDER FLEMING It began BY ACCIDENT with Penicillin…

It turns out _ I _ _ O B _ S kill microbes!

It turns out MICROBES KILL MICROBES!

MICROBIOLOGISTS pit all sorts of bacteria, fungi or protists against each other in deathmatches!

Microbiologists pit all sorts of bacteria, fungi or protozoa against each other in deathmatches!

Microbiologists pit all sorts of bacteria, fungi or protozoa against each other in deathmatches!

The GOOD microbes that WIN are turned into ANTIBIOTICS!

The GOOD microbes that WIN are turned into ANTIBIOTICS!

90% of ANTIBIOTICS medicine are made from bacteria & fungi that are harmless to us, but deadly to pathogens!

90% of ANTIBIOTICS medicine are made from bacteria & fungi that are harmless to us, but deadly to pathogens!

And antibiotics were discovered by ACCIDENT by Alexander Fleming in 1928.

ANTIBIOtics KILL LIVING CONTAGIONS: Bacteria Fungi Protozoa (protists) but DO NOT overuse or pathogens adapt and become resistant

ANTIBIOtics KILL LIVING CONTAGIONS: Bacteria Fungi Protozoa (protists) BIG PROBLEM but DO NOT overuse or pathogens adapt and become resistant

The World Health Organization (WHO) just released the 12 deadliest bacteria on Earth right now...ALL have built up resistance to our antibiotics.

ANTIBIOtics KILL LIVING CONTAGIONS: Bacteria Fungi Protozoa (protists) BIG PROBLEM but DO NOT overuse or pathogens adapt and become resistant

WHAT ABOUT STOPPING VIRUSES???

How can you KILL what’s NOT ALIVE??

To stop viruses, we WARN our body’s immune system…

To stop viruses, we WARN our body’s immune system with a VACCINE!

To stop viruses, we WARN our body’s immune system with a VACCINE!

To stop viruses, we WARN our body’s immune system with a VACCINE! vaccines for viruses

VACCINES DON’T DESTROY like antibiotics.

VACCINES DON’T DESTROY like antibiotics. Instead, VACCINES PREVENT!

Here’s how VACCINES work: Microbiologists find a harmless relative of a dangerous virus

Here’s how VACCINES work: Microbiologists find a harmless relative of a dangerous virus. Doctors inject this harmless virus into your body.

Now your body’s immune system has a way to ID the “bad virus” when it arrives.

VACCINES WARN OUR IMMUNE SYSTEM to be ON THE LOOKOUT for a nastier brother virus.

HOW???

…by making ANTIBODIES!!! OUR VACCINATED IMMUNE SYSTEM MAKES LITTLE MOLECULAR FLAGS that TAG BAD MICROBES IN OUR BLOOD!

TO STOP INFECTIOUS DISEASES: ANTIBIOTICS KILL BACTERIA PROTISTS FUNGI

TO STOP INFECTIOUS DISEASES: ANTIBIOTICS KILL BACTERIA PROTISTS FUNGI LIVING MICROORGANISMS

TO STOP INFECTIOUS DISEASES: ANTIBIOTICS KILL BACTERIA PROTISTS FUNGI LIVING MICROORGANISMS but DO NOT OVERUSE or pathogens adapt and become RESISTANT!

TO STOP INFECTIOUS DISEASES: ANTIBIOTICS KILL VACCINES PREVENT BACTERIA PROTISTS FUNGI VIRUSES + LIVING MICROORGANISMS but DO NOT OVERUSE or pathogens adapt and become RESISTANT!

TO STOP INFECTIOUS DISEASES: ANTIBIOTICS KILL VACCINES PREVENT BACTERIA PROTISTS FUNGI VIRUSES + Now even microbiologist have even reprogrammed viruses to attack living pathogens!
