Weird Killer Disease of Human from Bites and Stings
There are various kinds of weird human diseases caused by animal or insect bites. Some diseases are caused by tick-borne disease or bites from infected animals or insects. Inhalation of dust that is infected with animal feces can also cause this type of weird human disease. Often times we associate mosquito bites with illnesses such as malaria, it is important to note that mosquitoes are also carriers of infectious diseases and that causes fatality to both humans and animals. Here is a list of weird killer diseases caused by insect bites and stings.
Updated: We also added diseases that are transmitted by insects and other animal carriers (not necessarily from bites or stings).
1) Dengue Fever
Some study say, Aedes Aegypti mosquito come out for their “prey” as early as 6:00 in the morning till 8:00 a.m and 4:00 pm to 6:00 p.m. before evening time.
Dengue fever, also known as the backbone fever, is an infectious disease caused by dengue virus from Aedes Aegypti mosquitos’ stings. Dengue fever usually last for 3 to 7 days, but if left untreated it will lead to hemorrhagic fever which is fatal. Patients with Dengue Fever are advised to increase their fluid intake to avoid dehydration.
Chikugunya virus is an insect-borne virus of the genus Alphavirus, and transmitted to human by Aedes mosquitoes, a virus carrier. Symptoms are similar to Dengue fever, that last 2 to 5 days with muscle pains and joints (arthralgic). Chikugunya means, “that which bends up virus” and come from Makonde language (Makonde Language- is spoken by the Makondes they are an ethnic group found in Eastern Africa).
Barmah Forest Virus
The Barmah Forest virus is a non-fatal disease transmitted by mozzies, or Cutex Annulirostris mosquito. In some cases, the virus is hosted by wild birds and marsupials. The virus cannot infect other people; however, symptoms such as the joint pain can last up to six months.
Lymphatic Filariasis Elephantiasis
Lymphatic Filariasis Elephantiasis virus, are transmitted to humans by a mosquito infected with parasitic worms called ” Wuchereria bancrofti, Brugia malayi and B. Timori. Elephantiasis disease is characterized by rough and thick skin. Lymphatic Filariasis Elephantiasis causes enlargement of the affected body part such as the legs and the genitals. Filariasis, or prodocomosis, is the medical term of Elephantiasis.
Murray Valley Encephalitis
Murray Valley encephalitis virus, is a disease endemic in Papua New Guinea and Australia. It can cause death or permanent neurological disease to patients.
Onyong’yong virus come from Nilotic language of Uganda and Sudan, which means “weakening of the joints”. The virus is transmitted by Anopheles mosquito bites, it is sometimes compared to dengue virus.
2) Trombiculosis or Chigger Bites
Chiggers are commonly found on the tip of grass-blades . Chiggers are related to mites and falls under the Trombiculidae family mites which are called ‘trombiculid mites’.
Untreate wound caused by animal or insect bites and cuts or deep-punctured wounds. Prolonged infections will lead to Tetanus infections and even gangrene.
3) Scabies or Seven Year Itch
The scabies disease also known as ” Seven Year itch”, is a contagious skin disease infection, caused by parasites–mites, called Sarcoptes Scabei, which digs under the patient’s skin. This skin disease causes severe itching and allergy. Scabies in animals are called, “sarcoptic mange”.
4) African Eye Disease or Loa loa Filariasis
African Eyeworm, also known as Calabar Swelling and Fugitive Swelling, is a skin and eye disease transmitted by the nematode worm known as Loa loa through Chrysops Callidus (deer fly) and Chrysops SPP (mango fly). The human is made as natural reservoir for this disease. The African eyeworm disease is very common in Cameroon, where Ogooue river is located and in which deerflies are the inhabitants.
5) Pneumocystis Pneumonia (PCP)
The Pneumocystis pneumonia (PCP) is a disease transmitted by yeast-like fungus. Recently, it was mistakenly classified as protozoa, Pneumocystis jirovecii. The pathogens of this disease is said to only affect humans. There were no evidence found that the same pathogens can infect animals. PCP infects the human lungs and for people who have weaker immune system this can cause them a huge problem.
Toxoplasmosis is a kind of parasitic disease contaminated by protozoan species such as “Toxoplasma Gondii”. These parasitic protozoa can infects warm blooded animals and humans are no exceptions. The most common host of Taxosplasmosis is the felid cat and warm blooded mammals are said to be the carriers. A human can get taxosplasmosis from a bite of the infected animals.
Myiasis is also infectious disease and is transmitted by parasitic dipterous fly larvae. These annoying larvae and make the animal or human’s necrotic or living tissue as their host. Myiasis can cause toxemia or septicemia (sepsis, a potential deadly condition caused by bacterial infection in the bloodstream) and can lead to anorexia.
Cholera is commonly endemic in Asia. The common cause of this weird disease is from uncooked food like oysters, clams and meat that were contaminated by parasitic flies. Contaminated water can also cause cholera and symptoms of this disease include vomiting and diarrhea. Without proper medical attention, the patients or victims often die of dehydration.
7) Lyme Disease
Lyme disease or Lyme boreliosis, is an infectious disease transmitted by tick bites. Symptoms of Lyme disease are: fever, headache, fatigue, depression and skin rashes (erythema migrans).
Typhus or Epidemic Louse-borne Typhus
Typhus – (also called, Camp fever, Jail fever, Hospital fever, Ship fever, famine fever, putrid fever, Louse-borne Typhus and Epidemic Louse-Borne Typhus) is a diseases caused by after-wars epidemic, natural calamity and Rickettsia Prowazekii bacteria. It is transmitted through bites of Pediculus Humanus Corporis (human body louse).
Typhoid fever is a common disease and affects many people worldwide. Human, animal or insect feces can contaminate food and water which then causes typhoid fever. The organism responsible for this infection can be attributed to Salmonella Enterica, Serovar Typhi. Typhoid fever symptoms can include a slow- progress of high fever, excessive sweating, gastroenteritis, and rose-colored rashes. Typhoid fever, if left untreated can lead to a much serious condition, can cause bradycardia, discomfort, uneasiness, severe headache, cough, nose bleeding and a decrease in the white blood cells (Leukopenia), and could be accompanied by Eosinopenia and Lymphocytosis
Pediculosis Pubis also called Crabs or Pubic Lice, is a really weird disease caused by “crab louse”, Phthirus Pubis. Phthirus Pubis, are parasites that infest and lives in human genitals . These pesky pests lives in other areas where hair grows, like eyelashes (Pediculosis Ciliaris) and armpits.
9) Tick-Borne Encephalitis (TBE)
Tick-borne Encephalitis (TBE) is a viral infections from Ixodes Ricinus or sheep ticks, which attacks the nervous system and lead to chronic meningitis, encephalitis or meningoencephalitis. TBE is known as a “neurological disorder”. Most patients inflicted with TBE disease, could have permanent pathological condition, such as injury or trauma (neuropsychiatric sequelae). Fatality is always a risk with TBE, thus, patients with this condition are monitored closely.
10) Cat Scratch Disease (CSD)
The Cat-scratch disease (CSD) or cat-scratch fever also known as “Inoculation lymphoreticulosis” and “Subacute Regional Lymphadenitis”, is a non-cancerous infectious disease, caused by Bartonella (intracellular bacterium). Children are most commonly infected– they can get CSE from cat bites or scratch. Cats are known to be the host of this pathogen.
11) Bartonella or Rochalimaea
Bartonella or Rochalimaea, is a low level of taxonomic of Gram-negative bacteria. Fleas, Sand-flies and mosquitoes are the insects to transmit the Bartonella disease to animals and humans, and most especially to cats. The cats or felines then transmit this to humans through a bite and or a scratch. Bartonella is also known as Cat-scratch disease.
Hantavirus is transmitted to human by rodent bites. Aside from rodent bites, Hantavirus can also be transmitted by urine, saliva or feces of rodents. This is a deadly disease and it can lead to hemorrhagic fever associated with renal syndrome (HFRS) and (HPS) hantavirus pulmonary syndrome.
13) Water borne Disease
Swimmers Itch also known as Carcarial dermatitis, is a human skin disease caused by infected water-borne Schistosomatidae, or parasitic flatworms.
Schistosomiasis or Bilharzia
Schistosomiasis also known as Bilharzia, Bilharziosis or snail fever, a parasitic disease transmitted to humans by species of trematodes or platyhelminth infection of Schistosoma, which are parasitic worms. The disease is a chronic disease and which can destroy human internal organs.A person with Bilharzia disease has a high risk of getting bladder cancer. Areas that are dominated by fresh water snails are known to be the origin (places) of this disease.
Leeches feed on blood; when leech bites, it keeps itself attached to its victim until it’s full
Once the leech is removed, the wound caused by the bite bleeds because of hirudin (is secreted by leeches that prevent coagulation). Leeches normally carries parasites, but these parasites are not necessarily threats to humans. However, any infected wound left untreated can cause bacterial infection and can cause serious problems. The common symptoms are red blotches, itchy rashes, swelling of bitten area, severe allergies, anaphylactic reactions, feeling faint, and dizziness. There are also times that the patients or individual who have this disease can have difficulty in breathing. African leeches found in Cameroon are later found out to be carriers of HIV and Hepatitis.
14) Bolivian Hemorrhagic Fever or Black Typhus
Bolivian Hemorrhagic fever also called Black Typhus or Ordog Fever, is a disease caused by Zoonotic infectious disease. This hemorrhagic fever is commonly prevalent in Bolivia (after Machupo virus) this deadly disease are caused by vesper mouse calomyscallosus. Symptoms are commonly with fever, discomfort, headaches and muscle pains and blood spots (petechia) and nose and gum bleeding, which is observed closely within the seven days.
15) Sodoku Fever
Sodoku fever also known as “rat-bite fever (RBF)”, is a bacterial zoonotic illness caused by Spirochaete Spirillum Minus, transmitted to humans by rat or other rodent family bites, saliva, increments, urine or scratch. Complications from this disease can lead to more serious condition, such as: Myocarditis, Endocarditis, Hepatitis, Splenomegaly, Meningitis and Lymphadenopathy (disease of the lymph nodes).
Puumala Virus (Hantavirus)
Bank Vole is the vector and reservoir of the Nephropathia Epidemica virus is a disease that infect humans through inhalation of dust from the Bank Vole’s droppings. It also can cause Hantavirus, which is also called Puumala Virus (named after Finland’s municipality, where the Hantavirus is commonly endemic.
16) H1N1 Influenza A Virus
H1N1 Influenza virus, most common flu epidemic in China and other countries. Strains of H1N1 are endemic to humans and some strains of H1N1 causes human flu infections. The H1N1 virus are endemic in Pigs (swine influenza) and chickens (Avian influenza).
Henipavirus, is a low level taxonomic member of Paramyxoviridae family, order Mononeyaviales, with Hendravirus and Nipahvirus members. Henipavirus are the reservoir of Pteropid flying foxes or bats, and are characterized by big contents of organisms. The host –zoonotic pathogens carries these viruses leading to chronic illness and death.
18) Creutzfeldt-Jakob Disease (CJD)
Creutzfeldt-Jakob disease (CJD), is a neurodegenerative brain disease which has no cure and oftentimes are fatal. The CJD are sometimes called human form of Mad Cow Disease. The Bovine Spongiform Encephalopathy, is the cause of Creutzfeldt-Jakob diseases in human. Prion is a type of infectious disease transmitted to human by eating contaminated beef meat. CJD symptoms are dementia leading to memory loss, hallucinations and change of personality.
19) Hepatitis B Virus
Hepatitis B virus is a type of virus – Ortho Hepadnavirus the virus are found with three other species such as; the Ground Squirrel Hepatitis virus, Woodchuck Hepatitis virus and Wooly yellow tailed monkey.
20) Marburg Virus
The Marburg virus, also known as Marburg Hemorrhagic Fever, is related to Ebola.
A person can survive this virus as long as he follows on a prompt treatment for continued recovery. MHF can cause inflammation of the internal organs. Internal organs such as the testicles, liver, transverse myelitis can get inflamed. Also, MHF can cause an eye disease called Uveitis and a salivary gland disease called parotitis. Note: testicles inflammation is called orchitis and liver inflammation is called hepatitis.
Ebola virus is compared to Marburg virus or Marburg Hemorrhagic Fever (MHF), which is blamed to monkeys as the host for the Ebola virus (EBOV). Humans infected by Ebola virus can cause hemorrhagic fever that can eventually cause death. Ebola is derived from the name Zairel (now Republic of Congo) river.
Patas monkeys, Wadi or Hussar monkeys are known as the natural reservoir of Ebola virus.
21) Snake Bites
Snakes are known as venomous animals and bites from snakes are fatal. There are snakes that are not that venomous, but snake bites or wound if untreated could lead to severe gangrene or necrosis of tissues.
22) Irukandji Syndrome
The Irukandji syndrome is the condition caused by Carukia Barnesi, a species of Irukandji jellyfish and Box Jellyfish (cubozoans). The Irukandji syndrome’s symptoms include vomiting, severe pain from the sting area, and rapid rise of blood temperature, cardiac arrest and death.
23) Spider bites or sting
Bites from spiders such as the Black-wishbone spider, causes “necrotic wound” if left untreated . In some cases though spiders are non-venomous;however, spiders can transmit other diseases to humans.
Bee and Wasps stings with Venom
Venomous insects or animals, have variety of toxins and a bite from these culprits can cause immediate death.
24) West Nile Virus
The West Nile virus, mainly affects animals and birds, but recently studies shows that it affect humans through infected mosquito bites which produces 3 kinds of infections to humans, such as, WNV, mild fever or Pyreia or Hyperthemia WNV and Meningitis WNV and Encephalitis (acute inflammation of the brain).
25) Severe Acute Respiratory Syndrome (SARS)
Severe Acute Respiratory Syndrome (SARS) is a respiratory disease in humans caused by SARS coronavirus (SARS CoV) and findings of atypical pneumonia or respiratory distress syndrome. Symptoms are flu-like fever, myalgia (muscle pain), lethargy (fatigue or exhaustion), gastro-intestinal symptoms, severe cough, sorethroat and shortness of breath.
