A lot of diseases came from people helping people giving birth and they weren’t wearing gloves. Also they should continue searching for drugs to find a way to cure cancer

# data[].attributes.body
Becuase they found solutions and vaccines and technology made it easier but before 100 years they didn't know what is bacteria and the bacteria was every where so because of that people died but after the technology people

# data[].attributes.body
Because we have better vaccines to fight the diseases and better antibodies and vaccines are more accessible now and that there is better hygiene condition around medical areas and during treatment and just everyday things we do are just more hygienic

# data[].attributes.body
These days we have medicine and vaccine to protect us from picking up diseases that’s why these days there are less people getting diseases

Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful, but under certain conditions, some organisms may cause disease.

Some infectious diseases can be passed from person to person. Some are transmitted by bites from insects or animals. And others are acquired by ingesting contaminated food or water or being exposed to organisms in the environment.

Signs and symptoms vary depending on the organism causing the infection, but often include fever and fatigue. Mild infections may respond to rest and home remedies, while some life-threatening infections may require hospitalization.

Many infectious diseases, such as measles and chickenpox, can be prevented by vaccines. Frequent and thorough hand-washing also helps protect you from most infectious diseases.

Symptoms

Each infectious disease has its own specific signs and symptoms. General signs and symptoms common to a number of infectious diseases include:

Fever

Diarrhea

Fatigue

Muscle aches

Coughing

When to see a doctor

Seek medical attention if you:

Have been bitten by an animal

Are having trouble breathing

Have been coughing for more than a week

Have severe headache with fever

Experience a rash or swelling

Have unexplained or prolonged fever

Have sudden vision problems

Request an Appointment at Mayo Clinic

Causes

Infectious diseases can be caused by:

Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.

Viruses. Even smaller than bacteria, viruses cause a multitude of diseases — ranging from the common cold to AIDS.

Fungi. Many skin diseases, such as ringworm and athlete's foot, are caused by fungi. Other types of fungi can infect your lungs or nervous system.

Parasites. Malaria is caused by a tiny parasite that is transmitted by a mosquito bite. Other parasites may be transmitted to humans from animal feces.

Direct contact

An easy way to catch most infectious diseases is by coming in contact with a person or animal who has the infection. Three ways infectious diseases can be spread through direct contact are:

Person to person. A common way for infectious diseases to spread is through the direct transfer of bacteria, viruses or other germs from one person to another. This can occur when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn't infected.

These germs can also spread through the exchange of body fluids from sexual contact. The person who passes the germ may have no symptoms of the disease, but may simply be a carrier.

Animal to person. Being bitten or scratched by an infected animal — even a pet — can make you sick and, in extreme circumstances, can be fatal. Handling animal waste can be hazardous, too. For example, you can acquire a toxoplasmosis infection by scooping your cat's litter box.

Mother to unborn child. A pregnant woman may pass germs that cause infectious diseases to her unborn baby. Some germs can pass through the placenta. Germs in the vagina can be transmitted to the baby during birth.

Indirect contact

Disease-causing organisms also can be passed by indirect contact. Many germs can linger on an inanimate object, such as a tabletop, doorknob or faucet handle.

When you touch a doorknob handled by someone ill with the flu or a cold, for example, you can pick up the germs he or she left behind. If you then touch your eyes, mouth or nose before washing your hands, you may become infected.

Insect bites

Some germs rely on insect carriers — such as mosquitoes, fleas, lice or ticks — to move from host to host. These carriers are known as vectors. Mosquitoes can carry the malaria parasite or West Nile virus, and deer ticks may carry the bacterium that causes Lyme disease.

Food contamination

Another way disease-causing germs can infect you is through contaminated food and water. This mechanism of transmission allows germs to be spread to many people through a single source. E. coli, for example, is a bacterium present in or on certain foods — such as undercooked hamburger or unpasteurized fruit juice.

Risk factors

While anyone can catch infectious diseases, you may be more likely to get sick if your immune system isn't working properly. This may occur if:

You're taking steroids or other medications that suppress your immune system, such as anti-rejection drugs for a transplanted organ

You have HIV or AIDS

You have certain types of cancer or other disorders that affect your immune system

In addition, certain other medical conditions may predispose you to infection, including implanted medical devices, malnutrition and extremes of age, among others.

Complications

Most infectious diseases have only minor complications. But some infections — such as pneumonia, AIDS and meningitis — can become life-threatening. A few types of infections have been linked to a long-term increased risk of cancer:

Human papillomavirus is linked to cervical cancer

Helicobacter pylori is linked to stomach cancer and peptic ulcers

Hepatitis B and C have been linked to liver cancer

In addition, some infectious diseases may become silent, only to appear again in the future — sometimes even decades later. For example, someone who's had a chickenpox infection may develop shingles much later in life.

Prevention

Infectious agents can enter your body through:

Skin contact or injuries

Inhalation of airborne germs

Ingestion of contaminated food or water

Tick or mosquito bites

Sexual contact

Follow these tips to decrease your risk of infecting yourself or others:

Wash your hands. This is especially important before and after preparing food, before eating, and after using the toilet. And try not to touch your eyes, nose or mouth with your hands, as that's a common way germs enter the body.

Get vaccinated. Immunization can drastically reduce your chances of contracting many diseases. Make sure to keep up to date on your recommended vaccinations, as well as your children's.

Stay home when ill. Don't go to work if you are vomiting, have diarrhea or have a fever. Don't send your child to school if he or she has these signs and symptoms, either.

Prepare food safely. Keep counters and other kitchen surfaces clean when preparing meals. Cook foods to the proper temperature using a food thermometer to check for doneness. For ground meats, that means at least 160 F (71 C); for poultry, 165 F (74 C); and for most other meat, at least 145 F (63 C).

In addition, promptly refrigerate leftovers — don't let cooked foods remain at room temperature for extended periods of time.

Practice safe sex. Always use condoms if you or your partner has a history of sexually transmitted infections or high-risk behavior.

Don't share personal items. Use your own toothbrush, comb and razor. Avoid sharing drinking glasses or dining utensils.

Travel wisely. If you're traveling out of the country, talk to your doctor about any special vaccinations — such as yellow fever, cholera, hepatitis A or B, or typhoid fever — you may need.

You could say  that infectious diseases are a things of the past because back then, the technology to cure them before they spread wasn’t available then it is now. That’s why on the graph, we could see over the years, the mortality rates due to infectious diseases has decreased. Living conditions of people have improved as well from the past so that is a big factor too.

It is partially thing of the past as the rate of mortality has decreased massively in the last 100 years, it happend because the medicine strongly developed over the years; there is many vaccines created for many diseases,drug development, antibiotics discovered. The hygiene rules has saved many lives, everyone knows the main ways you can get the diesease from

People are adapt with the disease overtime as we now know why the disease caused so we know how to prevent from it. We create new medicine to cure from an infectious disease. Also 100 years ago, they didnt know what a bacteria is since theres no proof to suggest that it exist. Know that we know, we have a better chance of curing from the disease since we know what to do and how to prevent from it.
