Hey Scholars!!
I hope your spring break was full of fun and rest. This week we are discussing Human Health risks. For this week's Post I would like you to choose a Biological Human Health Hazards (Pathogen), such as a viral or bacterial disease and post the symptoms, who is most affected, how it is contracted, and how to fight the hazard.
Have a great week back!!!

Botulism
ReplyDeleteAll types of botulism produce symptoms that affect the nervous system. The classic symptoms of botulism include double vision, blurred vision, drooping eyelids, slurred speech, difficulty swallowing, dry mouth and muscle weakness that goes down the body, first the shoulders, then upper arms, lower arms, thighs, calves, feet. If untreated these symptoms may progress to paralysis. Infants with botulism appear lethargic, feed poorly, are constipated, and have a weak cry and poor muscle tone.
All canned and preserved foods should be properly processed and prepared. Persons who do home canning should follow strict hygienic procedures to reduce contamination of foods. Because the botulism toxin is destroyed by high temperatures, persons who eat home-canned foods should consider boiling the food for 10 minutes before eating it to ensure safety. Bulging containers should not be opened and foods with an unusual smell should not be eaten or even tasted. Canned food with bulging lids should be thrown away. Identified sources of infant botulism, such as honey, should not be fed to infants.
anyone can be affected

Leptospirosis
Leptospirosis is a bacterial disease that affects humans and animals. Outbreaks of this disease are generally caused by exposure to water contaminated with the urine of infected animals. Leptospira organisms have been found in cattle, pigs, horses, dogs, rodents, and wild animals. Humans become infected through contact with water, food, or soil containing urine from these infected animals. The time it takes a person who is exposed to Leptospirosis to encounter symptoms is between two days and four weeks. Symptoms of Leptospirosis include high fever, severe headache, chills, muscle aches, and vomiting, and may include jaundice (yellow skin and eyes), red eyes, abdominal pain, diarrhea, or a rash. Luckily, Leptospirosis can be treated with the use of antibiotics by mouth and through veins.

Leprosy
Symptoms:
1. Skin lesions that are lighter than your normal skin color and have a decreased sensation to touch, heat, or pain,
2. Numbness or absent sensation in the hands, arms, feet, and legs, and
3. Muscle weakness
Who is affected:
Children are more commonly affected than adults by leprocy. Leprosy is common in many countries worldwide, and in temperate, tropical, and subtropical climates. Approximately 100 cases a year are diagnosed in the United States, mostly in the South, California, Hawaii, and U.S. island possessions.
How it is contracted:
Leprosy is caused by the organism Mycobacteriumleprae. Leprosy is not easily transmitted but a person can become affected if they come into direct contact with an untreated person.
Ways to fight it:
1. A number of different antibiotics are used to kill the bacteria that cause the disease.
2. Aspirin or thalidomide are used to control inflammation.
3. Isolation is not necessary
Syphilis
ReplyDeleteThe route of transmission of syphilis is almost always through sexual contact, although there are examples of congenital syphilis via transmission from mother to child in utero.
Syphilis can generally be treated with antibiotics, including penicillin. If left untreated, syphilis can damage the heart, aorta, brain, eyes, and bones. In some cases these effects can be fatal.

"Syphilis is a sexually transmitted infection caused by Treponema pallidum – a specific type of bacteria called a spirochete."~ menshealth.com
ReplyDeleteIt affects 16-40 year old the most because they are the most active sexualy and it is transmitted sexualy and has four stages. The symptoms include sores on the area exposed to the infection.
Plasmodium Parasite:
ReplyDeleteThe Malaria parasite is developed in female mosquito where when it bites humans the sporozites of the plasmodium penetrate the liver and once developed enters the bloodstream of the human. Malaria destroys blood cells, causes intense fever, chills, anemia, headaches, weakness and vomiting. People living in poor African countries are the most likely to contract Malaria.

Rickettsia Bacterium
ReplyDeleteThe Rickettsia survival depends on entry, growth, and replication within the cytoplasm of eukaryotic host cells (typically endothelial cells).[1] Because of this, Rickettsia cannot live in artificial nutrient environments and are grown either in tissue or embryo cultures (typically, chicken embryos are used). Rickettsia species are carried as parasites by many ticks, fleas, and lice, and cause diseases such as typhus, rickettsialpox, Boutonneuse fever, African tick bite fever, Rocky Mountain spotted fever, Australian Tick Typhus, Flinders Island Spotted Fever and Queensland tick typhus [2] in human beings.They have also been associated with a range of plant diseases.They are thought to be the closest living relatives to bacteria that were the origin of the mitochondria organelle that exists inside most eukaryotic cells.

ReplyDeleteMalaria
Malaria is a mosquito-borne disease caused by a parasite. People with malaria often experience fever, chills, and flu-like illness. Left untreated, they may develop severe complications and die. Each year 350-500 million cases of malaria occur worldwide, and over one million people die, most of them young children in sub-Saharan Africa. To prevent malaria avoid mosquitoes, use preventive medication,and use insect repellent.
Staphylococci are Gram-positive spherical bacteria that occur in microscopic clusters resembling grapes

Monkeypox
What is it?
a rare smallpox-like disease that occurs primarily in the rain forest countries of central and west Africa
How can humans get it?
Monkeypox can spread to humans from an infected animal through an animal bite or direct contact with the animal's lesions or body fluids. The disease also can be spread from person to person
What are the symptoms?
first fever, headache, muscle aches, backache, swollen lymph nodes, a general feeling of discomfort, and exhaustion. then a papular rash
IS there a cure?
Currently, no treatment is available for monkeypox. Smallpox vaccine has been reported to reduce the risk of monkeypox among previously vaccinated persons in Africa
mwahahha. I choose the T-Virus. if i remember correctly:
ReplyDeleteSymptoms of theT-Virus (Tyrant Virus):
-Brain Deterioration (Lack of knowledge)
-Increase in Hunger
-Mutation (Bones would become displaced, skin would rip itself apart, Etc.)
-Body Deterioration (Skin and flesh dissolving)
-Increase in Adrenaline
-Increase in Human Limits (Agility, Strength, Stamina, Etc.)
-The ability to keep all bodily functions in full capacity (Live forever)
Commonly used and is released in the air, causing inhilation. Affects everyone. turns you into a zombie. Also it is mainly transferred by contact of blood. such as a bite or scratch from the living dead could cause you to become one.
possibly the future of biochemical warfare. hope that doesn't come true.

ReplyDeleteThe ebola virus!
http://www.who.int/csr/disease/ebola/en/
Ebola haemorrhagic fever (EHF) is a viral haemorrhagic fever and one of the most virulent viral diseases known to humankind.
The Ebola virus was first identified in the western equatorial province of Sudan and in a nearby region of Zaire (now Democratic Republic of the Congo) in 1976 after significant epidemics in Nzara, southern Sudan and Yambuku, northern Zaire.
There are five distinct species of the Ebola virus: Bundibugyo, Côte d’Ivoire, Reston, Sudan and Zaïre. Bundibugyo, Sudan and Zaïre species have been associated with large outbreaks of Ebola haemorrhagic fever (EHF) in Africa causing death in 25-90% of all clinically ill cases, while Côte d’Ivoire and Reston have not.
The Ebola virus is transmitted by direct contact with the blood, body fluids and tissues of infected persons. Transmission of the Ebola virus has also occurred by handling sick or dead infected wild animals (chimpanzees, gorillas, monkeys, forest antelope, fruit bats). The predominant treatment is general supportive therapy.
Malaria is a mosquito-borne infectious disease caused by a eukaryotic protist of the genus Plasmodium. It is widespread in tropical and subtropical regions, including parts of the Americas (22 countries), Asia, and Africa. Each year, there are approximately 350–500 million cases of malaria,[1] killing between one and three million people, the majority of whom are young children in sub-Saharan Africa.[2] Ninety percent of malaria-related deaths occur in sub-Saharan Africa. Malaria is commonly associated with poverty, but is also a cause of poverty[3] and a major hindrance to economic development. Symptoms include: fever, shivering, arthralgia (joint pain), vomiting, anemia (caused by hemolysis), hemoglobinuria, retinal damage,[10] and convulsions. To fight the dissease, you can get vaccinated and sleep in a mosquito net.

ReplyDeleteE coli
E coli is a rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms E coli is mostly harmless, but some strands can cause serious food poisoning. Symptoms include heavy and persistant vomiting, severe cramps and bloody diarrhea. It is contracted when people eat under cooked ground beef, drinking contaminited water or unpastuerized milk, or working with cattle.
You can prevent this disease by thoroughly cooking meat and washing hands after working with livestock. Anyone is can get this disease, but symptoms are more severe in children and older adults.

Lyme Disease
Lyme disease is caused by the bacterium Borrelia burgdorferi (B. burgdorferi). Certain ticks carry these bacteria. The ticks pick up the bacteria when they bite mice or deer that are infected with Lyme disease. You can get the disease if you are bitten by an infected tick. Lyme disease was first reported in the United States in the town of Old Lyme, Connecticut, in 1975. Cases have now been reported in most parts of the United States. Most of the cases occur in the Northeast, upper Midwest, and along the Pacific coast. Lyme disease is usually seen during the late spring, summer, and early fall.
Symptoms:
Not everyone infected with these bacteria gets ill. If a person does become ill, the first symptoms resemble the flu and include: Chills, Fever, Headache, Lethargy, Muscle pain, Body-wide itching, Joint inflammation, Stiff neck, Unusual or strange behavior.
Risk factors for Lyme disease include:
Having a pet that may carry ticks home, Doing activities that increase tick exposure (for example, gardening, hunting, or hiking), Walking in high grasses.
Prevention
When walking or hiking in wooded or grassy areas:
Spray all exposed skin and your clothing with insect repellant (spray outdoors only, do not use on face, use just enough to cover all other exposed skin, don't spray under clothing, don't apply over wounds or irritated skin, wash skin after going inside)
Wear light-colored clothing to make it easier to spot ticks
Wear long-sleeved shirts and long pants with the cuffs tucked into shoes or socks
Wear high boots, preferably rubber
Check yourself and your pets frequently during and after your walk or hike.
Ticks that carry Lyme disease are so small that they are very hard to see. After returning home, remove your clothes and thoroughly inspect all skin surface areas, including your scalp.

When I tested the Andis water I noticed that the water I tested the dish water, the tap water an the sanitary water. The dish water had less tubudity than normal so it was close to nuetral and the only reason it was n ot closer to nuetral was probably because it had Dawn dish washing liquid in it. The tap water was close to nuetral, this is good I was suprised because I always thought maysville water was nasty. What disturbed me was that there was no bleach in the sanitary water, which would have made the water basic. THis could have been because the waitstaff was just making new bleach water and had yet to put it in there.

Small pox is an infectious disease, unique to humans that attacks the skin, throat and mouth cells of the body. Unlike chicken pox which are centered around the torso of the body, Small pox are usually found on the extrmeities and the face. Small Pox is characterized by high fevers and severe rashes that transform into fluid-filled blisters. If the small pox vaccine is administered within three days of exposure, it will prevent or lessen the symptoms of the disease.
ReplyDeleteAnthrax...a commonly known CDC
ReplyDelete•Encapsulated, aerobic, gram-positive, spore-forming, rod-shaped (bacillus) bacterium
Systems Affected •Skin or cutaneous (most common)
•Respiratory tract or inhalation (rare)
•Gastrointestinal (GI) tract (rare)
•Oropharyngeal form (least common)
Transmission •Skin: direct skin contact with spores; in nature, contact with infected animals or animal products (usually related to occupational exposure)
•Respiratory tract: inhalation of aerosolized spores
•GI: consumption of undercooked or raw meat products or dairy products from infected animals
•NO person-to-person transmission of inhalation or GI anthrax

Treatment
(See Cutaneous Anthrax Treatment Protocol for specific therapy)
•Obtain specimens for culture BEFORE initiating antimicrobial therapy.
•Do NOT use extended-spectrum cephalosporins or trimethoprim/sulfamethoxazole because anthrax may be resistant to these drugs.
Precautions •Standard contact precautions. Avoid direct contact with wound or wound drainage.
Shingles
ReplyDeleteThe symptoms include itching, tingling, burning, constant aching, or a deep, shooting, or "lightning bolt" pain on any part of the body.
People who have HIV/AIDS, Cancer, and recieving radiation treatment are most liking to contract shingles.
Stress and fatigue help cause shingles.
The VZV vaccine and Zostavax may decrease the incidence of shingles
Siera Young
ReplyDeleteMononucleosis is most commonly caused by the Epstein-Barr virus (EBV), and it is most frequently diagnosed in teenagers and young adults.Mononucleosis generally resolves without medical help, though it may last from weeks to months. Treatment is aimed at easing the symptoms of the illness, and it can usually be done at home with plenty of rest, fluids, and over-the-counter medications. Serious complications only rarely occur. The most common symptoms of mononucleosis are fever, sore throat, swollen glands (lymph nodes), and fatigue. Symptoms usually develop between four to six weeks after exposure to the EBV. Other signs and symptoms of mononucleosis may include the following:
headache,
rash,
malaise,
loss of appetite,
jaundice,
tonsillitis,
body aches,
enlarged spleen and/or liver,
abdominal pain, and
difficulty breathing.
In younger children, the symptoms may be more subtle and may additionally include irritability and poor feeding. Mononucleosis most often occurs in people between 5-25 years of age, with the highest occurrence rate between 15-25 years of age.
Tuberculosis or TB
ReplyDeleteis a common and often deadly infectious disease caused by various strains of mycobacteria in humans, it usually attacks the lungs but can effect other parts of the body.
Symptoms
chronic cough, fever, night sweats, and weight loss. if other body parts are infected, symptoms vary.
Treatment
the use of antibiotics over a long period of time. antibiotics are being resisted more often.
to catch TB you have to inhale large amounts of the bacteria for a long period of time. TB is an airborn disease
most affected
Persons with HIV infection or other diseases that weaken the immune system
Persons in close contact with someone who has TB disease
Homeless persons
Persons from countries were TB is common
Persons in nursing homes

Influenza (FLU)
ReplyDeleteInfluenza or the flu is a respiratory system disease diseases system caused by influenza-viruses.
Human influenza virus is transmitted from one person to the other through the air droplets expelled during coughing an sneezing. The virus infects the mucous membranes of the upper respiratory tract and occasionally invades the lungs.
Symptoms include a low grade fever lasting for 3-7 days, chills, fatigue, headache and general aching. Recovery usually takes place rapidly. The antiviral drugs amentadine, rimantadine, zanamivir and oseltamivir has been shown to reduce the duration if administered during first two days of illness.
At present, three influenza A virus subtypes are epidemic in humans (H1N1, H2N1 and H3N2). Ifluenza infections frequently occur during winter and the school going children are more susceptible to the diseases.

Botulism
ReplyDeleteTHe diease is most often found in children but its possible to get it as an adult. It effects the muscles and some of the nervous system and can cause nausea and other cold like symptoms. You can get this by colonization of the digestive tract by the bacterium in children or adults, by ingestion of toxin from foodstuffs or by contamination of a wound by the bacterium. This can be prevented by heating stuff at 121 for three minutes before consumption.
Clostridium Perfringens
ReplyDeleteit is a anaerobic bacteria that is widely distributed in the environment. it also can occur in human and animal intestines. It can affect people that eat undercooked poultry. some symptoms are Diarrhea (often bloody), abdominal cramps, nausea, and headaches. it typically lasts 1-10 days
