Infectious diseases are caused by germs, which are tiny living organisms. Potentially, these organisms are infinitely transferable to fresh bodies.
Infectious diseases cause more deaths worldwide than any other single agent. These are the four main types of unhealthy germs causing diseases:
Since infectious organisms are found in air, soil and water, you may become infected just by;
- eating
- kissing
- drinking
- touching
- breathing
- insect bites
- from animals
- sexual contact
Many microorganisms live on or in your skin, mouth, upper airways, intestine and genitals without causing disease.
Whether a microorganism lives as a harmless companion or causes a disease depends on the microorganism’s nature and the state of your immune system.
Communicable diseases are transmitted from one source to another by infectious bacteria or viral organisms. Contagious diseases are very communicable, spreading rapidly from one person to another via contact or close proximity. Some germs are communicable and/or contagious, while others are not, i.e. food poisoning.
Contagious, communicable or noncommunicable infectious diseases, posing a health risk, have always existed. To control the spread of a contagious infectious disease is by limiting exposure. Isolation and quarantine are two main strategies. The difference between the two are:
- isolation applies to those known to be ill
- quarantine applies to those who have been exposed, ill or not
Many infectious diseases may never be a risk for you. Yet, global travel brings some around that previously never existed. The following offers a peak at the extent of infectious diseases worldwide by germ category.
Sample list of viral infections disease types:
- HPV
- AIDS
- SARS
- rabies
- rubella
- roseola
- mumps
- measles
- norovirus
- lassa fever
- yellow fever
- poliomyelitis
- conjunctivitis
- viral hepatitis
- Dengue fever
- common cold
- influenza ~ flu
- viral meningitis
- West Nile virus
- viral pneumonia
- viral encephalitis
- smallpox ~ variola
- Colorado tick fever
- viral gastroenteritis
- roseola sixth disease
- chickenpox ~ varicella
- fifth disease parvovirus
- herpes simplex & zoster
- cytomegalovirus infection
- infectious mononucleosis
- Marburg, ebola haemorrhagic fever
- progressive multifocal leukencephalopathy
- hand, foot and mouth disease ~ coxsackie
Antibiotics do not work if you have a viral infection, although there are a couple antiviral medicines available. And vaccines can help prevent several virus causing infectious diseases.
Sample list of bacterial infectious diseases types:
- stye
- MRSA
- E. coli
- typhus
- plague
- Q fever
- tetanus
- cholera
- anthrax
- syphilis
- pink eye
- impetigo
- botulism
- tularemia
- trachoma
- chalazion
- listeriosis
- diphtheria
- gonorrhea
- blepharitis
- chlamydia
- brucellosis
- shigellosis
- psittacosis
- melioidosis
- nocardiosis
- scarlet fever
- tuberculosis
- legionellosis
- leptospirosis
- typhoid fever
- salmonellosis
- Lyme disease
- campylobacteriosis
- bacterial meningitis
- cat scratch disease
- Hansen’s disease leprosy
- pertussis whooping cough
- pneumococcal pneumonia
- UTI ~ cystitis, pyelonephritis
- Rocky Mountain spotted fever
Antibiotics treat many bacterial infectious diseases.
Sample list of fungal infectious disease types:
- candidiasis
- aspergillosis
- blastomycosis
- histoplasmosis
- cryptococcosis
- coccidioidomycosis
- tinea cruris ~ jock itch
- tinea capitis ~ ringworm
- tinea pedis ~ athlete’s foot
Fungi are difficult germs to kill. Oral antifungal drugs are available for serious infections. And for skin and nail infections, topical medications go to work on fungus causing infectious diseases.
Sample list of parasitic infections disease types:
- malaria
- scabies
- myiasis
- filariasis
- taeniasis
- giardiasis
- amebiasis
- ascariasis
- babesiosis
- trichuriasis
- fascioliasis
- pediculosis
- isosporiasis
- enterobiasis
- toxocariasis
- trichinellosis
- clonorchiasis
- cysticercosis
- leishmaniasis
- dracunculiasis
- toxoplasmosis
- trichomoniasis
- fasciolopsiasis
- onchocerciasis
- echinococcosis
- hymenolepiasis
- metagonimiasis
- chagas disease
- schistosomiasis
- trypanosomiasis
- gnathostomiasis
- cryptosporidiosis
- diphyllobothriasis
- African trypanosomiasis
- free living amebic infection
Prevention is especially important, as there are no vaccines for parasitic diseases. However, some medications are available for their treatment.
Emerging infectious diseases are those that are first described within the last 20 years. A couple falling into this category include:
- SARS
- avian flu
- Nipah virus
- ehrlichiosis
- anaplasmosis
- West Nile virus
- mad cow disease
- human metapneumovirus
- hantavirus pulmonary syndrome
Because children have maturing immune systems and are often in close proximity to one another, these factors make it easier for transmitting contagious diseases. Notorious childhood contagious diseases commonly discovered running around the playground include:
- rubella
- roseola
- scabies
- measles
- pink eye
- ringworm
- chickenpox
- scarlet fever
- fifth disease
- hand-foot-and-mouth disease
Several measures can help you protect against communicable, contagious infectious diseases:
- vaccinations
- frequent hand washing
- antibiotics given ahead of the infection
- wear gown, mask, gloves in highly contagious environments
- avoid animal borne diseases via no contact with their waste, saliva, dander
Lower your odds for being overwhelmed by a infectious disease through maintaining the health of your immune system via proper diet and regular exercise. It is what it is, and doesn’t get any easier. “Live Pro Health”
