Infectious diseases

Let's talk. What are infectious diseases and what do they entail?
Good day Elliot.
Well, infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Now, many organisms live in and on our bodies. They're normally harmless or even helpful. But under certain conditions, some organisms may cause disease.

Alright.
And their mode of transmission?

Alright.
And their mode of transmission?
Hello, Rokey.
Okay, well, some infectious diseases can be passed from person to person. Some are transmitted by insects or other animals. And you may get others by consuming contaminated food or water or being exposed to organisms in or within the environment..

Alright.
And their mode of transmission?
Well, it wouldn't hurt you to also know that 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..

Hey Rainbow...
Well, now 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.
Also in addition, certain other medical conditions may predispose you to infection, including implanted medical devices, malnutrition and extremes of age, among others...

Can we dive a little to talk about the agents aforementioned that are responsible for infectious diseases please?

Certainly, Elliot it's fun learning yeah?
As I earlier said, 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 too.
And then we have Parasites that are responsible for the well known disease, malaria. It may interest you to know that malaria is caused by a tiny parasite that is transmitted by a mosquito bite. Other parasites may be transmitted to humans from animal feces too..

Do all infectious diseases have the same symptoms?

Not exactly, Rokey.
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 need hospitalization.
Now, general signs and symptoms common to a number of infectious diseases include:
Fever
Diarrhea
Fatigue
Muscle aches
Coughing... Etc.

What is responsible for chicken pox, and is it true that it happens to be a one-time experience if one ever contracts it?

Hi Rainbow,
So, chickenpox infection is caused by a Virus known as the varicella-zoster virus. It can spread through direct contact with the rash, and can also spread when a person with the chickenpox coughs or sneezes and you inhale the air droplets.
Also, it is highly contagious to people who haven't had the disease or been vaccinated against it.
And as to whether it's a one time disease?
Well, though uncommon, you can get chickenpox more than once. The majority of people who have had chickenpox will have immunity from it for the remainder of their lives.
You may be susceptible to the chickenpox virus twice if:
-You had your first case of chickenpox when you were less than 6 months old.
- Your first case of chickenpox was extremely mild.
- You have a weakened immune system.
And in some cases, a person who appears to be developing chickenpox for the second time is actually having their first case of chickenpox. Some rashes can mimic chickenpox. It may be that that person actually never had chickenpox before, but instead received a misdiagnosis.

Hi again, Lewis.
So, can health complications arise from contracting any infectious disease?

Hi again, Lewis.
So, can health complications arise from contracting any infectious disease?
Well, 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,
Also 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 chickenpox may develop shingles much much later in life..
So, it's a 50-50 chance.

At what point does one need to book a doctor's appointment?

Now while some infectious diseases could come with mild effects, others don't. So, it is important to seek medical attention if you:
1. Have been bitten by an animal
2. Are having trouble breathing
3. Have been coughing for more than a week
4. Have severe headache with fever
5. Experience a rash or swelling
6. Have unexplained or prolonged fever
7. Have sudden vision problems... Etc

This way you can be properly checked up, diagnosed and treated.

Refering back to my question again, can anyone tell us how to go about preventing infectious diseases?
Hey there, Elliot.
Interesting topic you've got there.
Well in response to your question...
Tips for preventing infectious diseases include:
- Regular washing of hands before cooking, eating and after eating, most importantly when you use the toilet. And try not to touch your eyes, nose or mouth often with your hands, as that's a common way germs enter the body.
- Get vaccinated against infectious diseases as they reduce your chances of contracting infectious diseases.
- Stay home when ill.
- Prepare food in a neat and sage environment.
- Don't share personal items such as combs, toothbrushes, razors. Also, 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...
These actions can go a long way in preventing one from contracting infectious diseases.

Thanks for this information, Ford.
I'm certain we've all learned a thing or two today!
