List Of Infectious Diseases


Here is the List of infectious diseases

Bacterial infection diseases


A bacterial infectious disease that is caused by the bacteria called Bacillus anthracis. It affects different body systems but mostly the respiratory, gastrointestinal, central nervous system and the cutaneous membranes. The symptoms vary according to the system it affects but mostly anthrax inflames the protective membranes of the cells.

Bacterial meningitis

Meningitis means an inflammation of the membranes or the meninges of the coverings of the spinal cord and the brain. Bacterial meningitis is caused by group B streptococcus such as the E. coli, Listeria monocytigenes, Neisseria meningitides, Streptococcus pneumoniae, and others.


This is a rare disease where the effects are serious and can paralyze a patient because of the botulinum toxin. The toxins are the metabolic waste of the Clostridium botulinum bacteria during anaerobic conditions. In adults, the toxins usually come from the food-borne botulism.


This is a very contagious illness where it is caused by a gram negative bacteria like Brucella. This occurs when a person ingests unsterilized or contagious milk from the animals infected by the bacteria. This is also called as the Bang’s disease, Malta fever, Crimean fever, Gibraltar fever and others.


This is an infectious disease caused by Campylobacter bacterium. This is called foodborne diseases where anybody who ingested food with these bacteria will experience blood stool diarrhea, fever, body pain and cramps.


Cholera is a foodborne disease where the transmission through the fecal-mouth route. The bacteria causing cholera is Vibrio cholera where a person ingests water or food that is infected with feces of the infected person. This causes diarrhea and vomiting and can cause dehydration and death if no treatment is done.


Diphtheria comes from Greek word “diphtheria” which means leather scrolls in pair. This disease affects the upper respiratory system because of the bacteria like Cornebacterium diphtheriae which is a gram positive bacterium that attaches to the pharynx, nasal cavity or the tonsils. The patient will present low grade fever and sore throat.

Epidemic typhus

This is also called as jail fever, hospital fever, famine fever and others. Epidemic typhus is caused by Rikettsia prowazekii and it got its name because of the epidemic it caused during natural disaster and war. This causes high grade fever, rashes, muscle pain that is severe, chills, and even low blood pressure and delirium.


This is one of the common causes of sexually transmitted diseases. The problem is caused by Neiserria gonorrhoae which thrives in warm and most area in the reproductive tract like the cervix and even goes deeper into the fallopian tubes and uterus.


An infectious disease caused by Staphylococcus aureus. This is also called as the school sores since it affects mostly pre-schoolers. This is a contagious problem which can infect anyone via body or close contact.


This is a fatal infection where the causative agents are gram negative bacteria that belong to the Legionella family. It is a respiratory problem where the signs and symptoms resemble that of the influenza virus. The legionellosis comes in 2 forms: the Pontiac fever and the Lehionnaire’s disease


This is also called as the Hansen’s disease where the causative agents are Mycobacterium leprae and Mycobacterium lepromatosis. It affects the upper respiratory tract specifically nerves and the mucosa. The obvious signs and symptoms are the skin lesions which can be damaging to the skin and nerves if it is untreated.


Leptospirosis is also called as the Weil’s syndrome, Rat catchers’ Yellows, 7-day fever, Bragg fever, Pretibial fever and others where it affects the spleen and causes nephritis as well as jaundice. This is one of the infectious conditions where the transmission comes from animals to human beings caused by the Leptospira family.


This is an infectious disease that mostly attacks immunocompromised individuals from infancy to elderly. The causative agent of Listeriosis is the Listeria monocytogenes which is a gram positive bacterium where the signs and symptoms include muscle pain, fever, vomiting and it affects 1 in every 5 persons.

Lyme disease

Lyme disease is an infectious tick-borne disease. It is caused by different bacteria in the genus Borrelia. Mainly there is an erythema or a circular skin rash which can later complicate the organs like the heart, the joints and the brain.


This means methicillin-resistant staphylococcus aureus. The bacteria are referred to as the “flesh-eating bacteria” because in MRSA it affects and destroys the skin. There is great weight loss and depletion of the muscles because the bacteria eat up the human flesh.


Pertussis is also called as the whooping cough. This is caused by bacteria called Bordetella pertussis where the cough starts out mildly and then becomes severe and high pitched. This mostly affects children and babies where when they breathe after coughing hard causes the whooping sound.

Pneumococcal pneumonia

This is a kind bacterial pneumonia where it affects the upper respiratory tract but it can also affect other parts of the body like the lungs, blood, nervous system and the middle ear if not treated. The causative agent is the streptococcus pneumonia which attacks children and adults.

Rocky Mountain spotted fever

It is a very lethal kind of bacterial infection that is caused by Rickettsia rickettsii. The mode of transmission is through vector-like ticks. Once the person is bitten by the tick, infection starts and shows signs and symptoms like muscle pains, headache and fever.


Salmonellosis affects the gastrointestinal system where the causative agent is the Salmonella bacteria. This condition happens when ingesting infected food like poultry, beef, eggs, chicken and even fruits and vegetables. There are abrupt signs and symptoms like fever, diarrhea, and abdominal cramps within 12 to 72 hours.

Scarlet fever

Scarlet fever is caused by the Streptococcus pyogenes where the most obvious sign and symptom is the strawberry appearance of the tongue. It becomes bright red with fever and sore throat and should be managed right away with antibiotics. The exotoxins released by the bacteria are fatal if not treated right away.


This is a food-born bacterial infection caused by the Shigella bacteria. This is also called as the Marlow syndrome or bacillary dysentery where it causes abdominal pain, cramps, fever, diarrhea, pus or mucus in the stool or even blood in the stool.


This is another sexually transmitted infection caused by Treponema pallidum. The syphilis happens through sexual contact where the signs and symptoms depend on the stages (primary to tertiary) the patient is in.


Is a serious condition caused by claustridium tetanii. The bacteria come from soil, manure or dusts that enter through an open wound. This will cause tingling of muscles and even leads to lock-jaw and patients can soon die of suffocation if not promptly treated.


This bacterial infection is caused by Chlamydia trachomatis which infects the eye through body contact or secretion. The contaminated objects like towels can cause the bacteria to enter the eye and leads to infection.


This is an infection that affects the respiratory system specifically the lungs through the causative agent- Mycobacterium tuberculosis. The bacteria may also affect other parts of the body like TB of the stomach or bones. A patient experiences chronic cough with or without sputum. Sometimes it is accompanied by blood-tinged sputum with fever and night sweats

Typhoid fever

Typhoid fever is a food-borne infectious disease where the mode of transmission is through the fecal-oral route. This is caused by Salmonella enteric where a person eats a contaminated food (feces). This is also called as the gastric fever or abdominal typhus, infantile intermittent fever or pythogenic fever.

Viral infections


AIDS stands for acquire immunodeficiency syndrome where it mainly attacks the body’s immune system and once this is down, opportunistic infections happen. AIDS is a severe form of HIV or human immunodeficiency virus and it is transmitted mostly through sexual intercourse, blood transfusions which are contaminated, mother to child transfer during pregnancy, breastfeeding and in rare instances pricking of needles.

Chicken pox

Chicken pox is caused by the varicella virus where it is transmitted through airborne. It mostly affects children but it can also affect adults. The usual signs and symptoms include fever, headache, itchy rashes that looks like blisters and it usually seen in the trunk, scalp and on the face.

Common colds

Medical term for common colds include rhinopharyngitis, acute coryza, or nasopharyngitis. This affects the upper respiratory system like the nose, pharynx and the throat. The signs and symptoms include cough, runny nose or colds, sore throat and sometimes fever.

Dengue fever

This viral infectious disease is caused by Aedes aegypti and those in the genus Aedes. This fever usually happens in tropical areas where signs and symptoms include skin rashes, joint pains, intermittent fever and headache. It can lead to dengue hemorrhagic fever since the platelet goes down and there is a risk of bleeding involved.

Ebola hemorrhagic fever

This is a fatal condition where the virus mainly responsible for the fever is the Foloviridae. This is common in the Philippines and the virus can be passed from animals to human beings. The infection process may also spread through droplet transmission when the body fluids of the infected person enter the body.


Is an inflammation of the liver caused by different group of viruses that affects the liver. There are different kinds of hepatitis ranging from A to E but the common ones are hepatitis A, B and C.

Herpes zoster

This condition is also called as shingles where the viruses cause painful skin rashes and blisters in selected areas of the body. The blisters or rashes are often in stripe and this is associated with the varicella zoster virus and even chickenpox.


This is also called as flu caused by the influenza virus. This is a contagious illness where it usually affects children and some adults. The usual signs and symptoms include fever, chills, runny nose, sore throat, weakness, loss of appetite and the like.


This is an infectious disease caused by the Morbillivirus that affects the respiratory system. This condition is also called as morbilli where it can affect through droplet or transmission for the affected person. Erythematous rash, fever, cough, runny nose and red eyes are the usual signs and symptoms of the disease


Mumps is also called as epidemic parotitis where it is caused by the mumps virus. This is a condition where the parotid gland which is one of the salivary glands is inflamed. This can also cause orchitis or the inflammation of the testicles where it can cause infertility if not promptly treated.


Poliomyelitis is also called as infantile paralysis where the mode of transmission is through the fecal-oral route. The virus enters the body and it affects the central nervous system causing muscle weaknesses, flaccid paralysis and even destroys the motor neurons. This disease shows now symptoms to more than 90% off the affected individuals.


Rabies is a viral disease where it causes encephalitis or inflammation of the brain because of the virus from the warm-blooded animals. The transmission is from animal to humans through animal bites.

Viral encephalitis

This is an infectious disease where there is inflammation of the brain because of a virus. This mostly happens as an effect of any acute infection caused by rabies virus, poliovirus, measles, and other viruses.

West Nile virus

This type of disease is caused by the virus in the Flaviviridae family. The mode of transmission is through a bite from mosquitoes and it appears asymptomatic in human beings infected with the disease

Yellow fever

This is a hemorrhagic disease that is caused by the Flaviviridae family. Yellow fever mostly affects in tropical and sub-tropical countries like South America and Africa.

Fungal infections


This is a kind of fungal infection where it is caused by the candida group or yeast. Candidiasis is also called as thrush where it affects the mouth and vagina but the yeast becomes systemic which can be a cause for systemic diseases.


This is a fatal fungal disease where it is caused by the crptococcus neoformans and the Cryptococcus gattii. This is an opportunistic disease mostly happening in patients with HIV/AIDs and is acquired through inhalation.


Histoplasmosis is a fungal infection caused by the Histoplasma capsulatum. It is also called as Darling’s disease or the Cave disease where the signs and symptoms show about 2 weeks after exposure. This is fatal when not treated promptly.

Tinea pedis

Tinea pedis is also called as athlete’s foot where it affects both feet of the patient. The feet appear to be flaky, scaling and very itchy caused by the fungi called Trichophyton. This is mostly transmitted when walking in barefoot in public bathhouses and showers


Parasitic infection

African trypanosomiasis

The Human African Trypanosomiasis is caused by Trypanosoma brucei. This is a protozoa that is found in the tsetse fly where it serves as the vector of the microorganism. The fly bite causes the introduction of the protozoa to the human body where adverse signs and symptoms are experienced. This is also called as the sleeping sickness or African lethargy.


This is a gastrointestinal protozoal infection caused by the Entamoeba histolytica. A person with amoebasis may be asymptomatic or the case becomes latent until it affects the person again. The usual signs and symptoms include dysentery, mild diarrhea, blood and mucus in the stool.


Ascariasisis also a protozoal infection where it is caused by a parasite called Ascaris lumbricoides. The infection happens through the fecal-oral route where there is ingestion of food with contamination like feces with the ascaris eggs. The larvae will then hatch and multiply in the intestine but it will also reach other parts of the body like the respiratory tract or lungs.


This is a condition wherein it is caused by the genus Babesia which is blood-sucking assassin bugs and shows signs and symptoms of the malaria bug. This is a rare condition that the affected individuals only get this when travelling into areas where babesiosis is endemic.


This is caused by the Chinese liver fluke or the Clonorchis sinensis. The mode of transmission is through the oral-fecal route where flukes are passed through the fecal matter and then the eggs are batched in the mollusks. This condition happens when the mollusk are undercooked and ingested.


Is a protozoan infectious disease caused by the fecal-oral mode of transmission. The causative agent is called the Taenia solium or commonly called as the pork tapeworm. This affects the gastrointestinal system as well as the brain


Dracunculiasis is a condition that affects the subcutaneous tissues of a person or animals like dogs, cats, cattle or horses. This is also called as the guinea worm disease where it is caused by the Dracunculus medinensis. Patients with this illness present a very painful and burning sensation blister in their lower extremities.


The enterobiasis is also called as the pinworm infection where the causative agent is the Enterobius vermicularis. This is a parasite that is transmitted through the fecal-oral route where an individual ingest the eggs of the pinworm in contaminated food. The most common symptom is the itching of the anus.


This is a kind of parasitic disease is transmitted through the oral-fecal route and it affects both animals and human beings. Echinococcus is a kind of tapeworm and the Echinococcus granulosus is the most common kind of parasite affects the human beings.


The fasciolasis is transmitted through the oral-fecal route where the causative agent is the Fasciola hepatica and the Fasciola gigantic. These are found in domestic animals which serve as host such as the sheep, pigs, cattle donkeys and others. When these animals are not thoroughly cooked, it will infect the human beings.


Filariasis occurs in tropical countries where the nematodes or the ringworm in the Filaroidea family infects the individual through vector transmission. The mosquitoes and the black flies are usually the vector and when it bites the human being the eggs of the nematodes are released into the lymphatic system.


Giadasis is a parasitic infection where it causes diarrhea and other gastrointestinal problems because of the microorganism called Gardia Lamblia. This is also called as the beaver fever where this can be transmitted via different route like person-to-peron, through a vector or water-borne infections.


This is a kind of infection where it is caused by tapeworms mainly the Hymenoplepis nana and the Hymenolepis diminuta. Most of the infections happen in tropical countries where the mode of transmission is through oral-fecal route.


Is a kind of parasitic infection where the parasite is the genus Plasmodium. Infection happens through vector transmission where the parasite is carried by the mosquito and bites a human being. The parasite attacks the liver and then in the red blood cells causing headache and fever. If this is not treated, it can cause death. Most microorganisms causing malaria include Plasmodium falciparum, Plasmodium vivix, Plasmodium ovale and others.


Metagonimiasis is a parasitic infection where it is caused by Metagonimus yokagawai which is an intestinal nematode. The infection is transmitted through the oral-fecal route.


This parasitic infection is also called as the river blindness or the Robles’ disease. The onchocerciasis is caused by the Onchocerca volvulus which is the leading cause of blindness. This condition is transmitted through vector transmission through the black fly. Once a person is bitten, the larvae of the nematodes spread systemically and affect the eye.


Scabies is a contagious infection where it the parasite that causes it is the Scarcoptes scabiei. This is a tiny tick and is regarded by the WHO water-related disease. It causes severe itching on the skin.


This is also called as the bilharzias or snail fever. The disease is caused by genus Schistosoma which are parasitic worms where they live in snails. A person is infected when they are exposed to contaminated water or snails which usually happen in developing countries where sanitation is poor.


Trichominiasis is a sexually transmitted disease caused by Trichomonas vaginalis. This is also called as the “trich” where it affects the genito-urinary tract.
