Hey Scholars!!
I hope your break was full of food and rest. Last week we discussed 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!!!

The bacterial pathogen Lyssavirus (genus)of the Rhabdoviridea family (Order Mononegavirales). This pathogen is well known for causing rabies.
ReplyDeleteThe Rabies Virus produces:
1)Flu-Like Symptons from two to twelve weeks, but can continue for up to two years.
2)Partial Paralysis, 3)Cerebral Dysfunction, 4)Anxiety, 5)Insomnia, 6)Agitation, 7)Abnormal Behavior, 8)Terror, 9)Paranoia, 10)Hallucinations, 11)Delirium, and 12) Death
The Rabies virus has around a 8% survival rate, and the humans that do survive usually end up with severe brain damage.
Prevention: Vaccinations for humans and widespread vaccination of domesticated cats and dogs. Vaccines had dropped the numbers of death by a huge amount, as it is only down to 1-2 deaths per year. Those deaths are most likey from bat bites, inwhich the person that was bit did not notice.
Bacillus anthracis is a bacterium that causes anthrax. It is found on almost every continent in some quantity and can be found in endospore form in soil where it can lay dormant for years at a time. Everyone can be infected but people who deal with the bodies of animals. It is contracted by inhalation of the spores and the ingestion of infected animal meat. Anthrax is being used as a biological weapon in many countries around the world as well. There is not much you can do to fight the hazard of anthrax because it does not have any specialized niche and can be found almost anywhere.
ReplyDeleteCholera Disease:
ReplyDeleteSymptoms:
severe watery diarrhea
vomiting
then dehydration
Who is affected:
Haitians at the moment. People in countries without proper water treatments.
How is it contracted:
By eating food or drinking water contaminated by feces from a person with the infection.
How is it treated:
No real treatment at the moment all doctors can do is hydrate a person infected and give so antibiotics to slow the diarrhea.

Chicken Pox
ReplyDeleteAn airborne disease that is easily spread through coughing or sneezing from sick persons or through direct contact with secretions from the rash. Mostly effects the very young since it is very hard to contract twice. There is a chickenpox vaccine if you want it but to fight off the chickenpox you just have to wait it out and try not to itch.

The Ebola Virus symptoms include fever, muscle pain, headache, and inflammation of the pharynx. Six days following vomiting and bloody diarrhea, individuals could develop maclopapular rash with bleeding at needle sites and body orifices. This virus can be transmitted through body fluids; the handling of dead animals and is highly infectious. People that work with animals are the most vulnerable seeing as animals carry it. You can fight this hazard by having basic hygiene; and getting a vaccine.

Early stage - Flu like symptoms,High fever,Chills, Shivering, Rigor, Headache, Malaise, Body aches, Muscle aches, Mild respiratory symptoms, and Diarrhea
Low respitory stage - Dry nonproductive cough, Shortness of breath, Difficulty breathing, Hypoxia, Hypoxemia, Pneumonia, Acute respiratory distress syndrome, Focal interstitial infiltrates on lung x-rays - in early respiratory phase, Generalized, patchy, interstitial infiltrates on lung x-rays - in later respiratory phase, Areas of consolidation on lung x-rays - in later respiratory phase
Contraction: Transmission of an infectious agent by another person by one or more of the following: saliva, air, cough, fecal-oral route, surfaces, blood, needles, blood transfusions, sexual contact, mother to fetus, etc. Read more at
People most at risk: Children and the Elderly
How to fight SARS: Treatments similar to atypical pneumonia, Antiviral agents, Oseltamivir, Ribavirin, Oral steroids, Intravenous steroids, Steroid and ribavirin combination, Steroids and other antimicrobials, Intubation, Mechanical ventilation - needed in about 10-20% of cases, Isolation, Anti-transmission protocols including standard, contact, and airborne precautions

Many viral diseases are transferred through blood and other bodily fluids like semen, vaginal fluid, and breast milk. For example, HIV/AIDS, and Hepatitis B and C. It affects the people who have it that have contact with others, like people who have sex and don't tell their partners they have it, or when women have babies, and then their babies are born with it.
The symptoms can vary, because the illnesses people with AIDS/HIV get are ones from bacteria and viruses that come from the failing immune system that AIDS/HIV causes. To prevent the spread of AIDS/HIV, people with it need to not come into close contact with uninfected people. They also need to be not allowed to reproduce.

Lyme Disease
ReplyDeleteSymptoms: rash, flu-like symptoms, heart and nervous system involvement (palsies, meningitis), motor and sensory nerve damage, brain inflammation, and arthritis
Humans are infected by ticks
-avoid brushy, overgrown grassy, and
wooded habitats
-remove leaves, tall grass and brush
from work areas

Strep Throat
ReplyDeleteSymptoms:
Severe and sudden sore throat without coughing, sneezing, or other cold symptoms.
Pain or difficulty with swallowing.
Fever over 101F. Lower fevers may indicate a viral infection and not strep.
Swollen lymph nodes in the neck.
White or yellow spots or coating on the throat and tonsils .
most affected:
usually school kids kids under 3 usually do not get it
contracted:
Strep Throat is transmitted directly from person to person by coughing, sneezing, and close contact. Very occasionally strep throat is passed through food, when a food handler infected with strep throat accidentally contaminates food by coughing or sneezing.
how to fight:
There is really no way to prevent getting strep throat. Some of the common ways to help prevent getting strep throat are: covering her mouth when she sneezes to keep from spreading the bacteria; wash their hands after sneezing, blowing their noses, and before cooking or eating; wash dishes, drinking glasses, and knives, forks, and spoons in hot, soapy water; and keep sores and cuts clean.

is small red bumps that resemble pimples, spider bites, or boils. Then the bumps become larger, more painful, and eventually open into deep, pus-filled boils. people with weak immune systems and athletics are most exposed to this infection. It can be attracted from skin contact with another person whose infected or by not proper cleaning your equipment.Vancomycin and teicoplanin are glycopeptide antibiotics used to treat MRSA infections

H1N1
ReplyDeleteFever – particularly a fever of over 100 degrees
Sore throat
Cough
Chills and fatigue
Body aches
Headache
Occasionally, vomiting and diarrhea
Trouble breathing, including rapid breathing.
Gray or bluish skin color
Not drinking enough fluids
Sleeping constantly and not interacting when awake
Being especially irritable
Not urinating or no tears when crying
The symptoms improve but then return with fever and worse cough.
The people most affected by it are the elderly, the young, the pregnant, people with chronic illnesses, people with asthma, and heavy smokers.
The virus is spread from person 2 person through coughing or sneezing, so avoid ppl w/flu or flu-like symptoms. Avoid touching things such as doorknobs w/flu virus on it.
You simply treat the symptoms that you may have from the virus.
the common cold is an upper respiratory infection that is caused by a virus. The symptoms are fever, sneezing, watery eyes, runny nose, headache, sore throat, and cough. It is passed through contact and is very contagious. To fight this virus, rest and fluids are encouraged. Anyone can get this, but children are prone to this virus.

ReplyDeleteAnthrax
Symptoms:first experience a small, raised sore that resembles an insect bite, but within days develops into a blister. Some symptoms seen with gastrointestinal anthrax can include nausea, bloody diarrhea, and vomiting blood.
There are vaccines for it to be treated
Usually found in Europe Africa and the middle east rarely found in US
Anyone can be affected because it can be transferred by skin through inhalation of digested
"Anthrax." Other Information. Web. 05 Dec. 2010. .
Anthrax:
ReplyDeletecaused by exposure to the spores of the bacteria Bacillus anthracis that become entrenched in the host body and produce lethal poisons. It is primarily a disease of grazing animals such as cattle, sheep, goats, and horses. Cutaneous (skin) anthrax causes a characteristic sore on the skin and results from exposure to the spores after handling sick animals or contaminated animal wool, hair, hides, or bone meal products. Inhalational anthrax results from breathing anthrax spores into the lungs. People who handle animal hides infested with spores may develop inhalational anthrax, known as woolsorter's disease. Once inhaled, the organisms multiply and may spread their toxins to the bloodstream and many other organs. Infection may spread from the liver, spleen, and kidneys back into the bloodstream, thus causing an overwhelming infection and death. Gastrointestinal anthrax results from eating meat products that contain anthrax. Gastrointestinal anthrax is difficult to diagnose. It can produce sores in the mouth and throat.
I'm choosing meningitis because its a disease that truly fascinates me. Oh my gosh I sound kinda like a science nerd for a third time in my life. (just kidding) but i'm going to focus on the BACTERIAL meningitis. Essentially, it is the swelling of the membranes surrounding the brain and spinal cord. The swelling occurs due to the presence of bacteria. It is serious and can be fatal. It's more likely to occur in children and young adults. If death doesn't occur, it is more than possible a limb will be amputated, or brain damage or kidney failure will be caused. There's a vaccination for it. YAY! It's transmitted through air droplets and direct contact; it's extremely contagious. At first meningitis seems like the average flu, so a improper diagnosis may occur. It's very very interesting.

Foodborne diseases are the illnesses contracted from eating contaminated food or beverages. There are more than 250 foodborne diseases. They are caused by viruses,bacteria,parasites,toxins,metals, and prions. Symptoms vary from mild gastroenteritis to life-threatening neurologic,hepatic,and renal syndromes. To fight the disease is just to stay away from contaminated foods and cook properly.

Reusing water after it has been used for chemicals use.
Since it is rare that most the chemicals aren't cleaned, some symptoms could be disfiguration, it all depends on the chemical that has been reused.
Humans would be mostly affected. Most reused water is used in water fountains and toilets and many other accessories.
You become affected with it just by drinking it and intaking it into your system.
The only way that you can fight this hazard is if you visibly see weird colors or if the water companies clean the water much better.
I chose the common cold. Symptoms include a runny or stuffy nose, sinus pressure, headache and sometimes fever or sore throat. Kids are the most like ones to catch a cold. It can be contracted from touching things that have been sneezed or coughed on or if the air is dry(that's why most people get a cold in the winter), Simple things can be done to prevent catching a cold such as always washing your hands and using hand sanitizer.
ReplyDeleteHIV
ReplyDeletesymptoms: fever, rash, swollen lymphnodes, muscle pains, mouth soars, and liver & spleen enlargement.
most affected: are people who have unsafe sex
contracted mostly through: unsafe sex, contaminated needles, breast milk, and from a mother to her child at birth
how to fight it: working on a new antibody that can help to cure it and they also use many HIV therapies.

Chikungunya Fever is a flu-like viral disease. Symptoms are severe headaches, aching joints, chills, nausea and vomiting. This virus greatly effects elder people who may have it for 1 to 2 months. It is contracted from mosquitos. The virus can be fought by common disinfectants, moist heat, and drying.

Salmonella is a pathogenic bacteria that can cause typhoid fever, paratyphoid fever, and foodborne illness. It is found worldwide in both cold and warm-blooded animals including humans. It is typically found in contaminated food and can multiply very rapidly. The best way to rid of salmonella is sanitation and proper preparation and storage of foods.
ReplyDeleteANTHRAX!!!!
ReplyDeletedeadly disease. a bacterial infection.
It can survive in the soil for over 70 years and must enter the body through an open wound, inhalation, or ingestion. Many animals are still affected per year.
The diease causes internal bleeding, destruction of tissues, and a build up of toxins in lethal doses to humans.
The disease can be fought with antibiotics and vaccines, however if administered late, antibiotics will kill the bateria but not the fatal toxins in the body.

Anthrax is caused by bacteria. It is contracted by contact with contaminated animal substances such as feces and hair. Anthrax is characterized by ulcerative skin lesions and some other symptoms include fever, swelling, and respiratory problems. It is contracted mostly in undeveloped nations where working conditions are not good. One way to prevent anthrax is by preventive measures such as making sure conditions among animals are well. http://www.answers.com/topic/anthrax
ReplyDeleteCholera is caused by bacteria in the intestines and is contracted by a person eating or drinking a substance with the bacteria. Diarrhea, vomiting, leg cramps, shock, and dehydration are all symptoms of this sickness. It takes place mostly in underdeveloped areas with poor sanitation, inadequate water treatment, and inadequate hygiene. Immediate replacement of loss fluids should be made when dealing with this illness. Washing hands, drinking boiled, chemically treated, or bottled water and eating foods cooked properly are all ways to prevent cholera from taking place. http://www.medicinenet.com/cholera/page3.htm
The brand EcoSmart makes pesticides that are relitively safe. The substances that they use are non toxic to both humans and to plants. The pesticides are also pretty safe for the environment as they contain natural ingredients. Even the spider blaster contains rosemary oil as well as other natural ingredients.

Arenavirus - Lassa
ReplyDeleteThe symptoms include: prodromal phase with fever, myalgia, vomiting, diarrhoea, followed by rash, liver dysfunction and convulsions. Arenaviruses are generally associated with rodents, however humans can contract the virus. The virus is transmitted through contact with the feces, urine, blood, or saliva of an infected rodent. Ribavirin has shown to be an effective treatment for Lassa fever (arenavirus), especially if used within the first week of contracting the illness.

Streptococcus pneumoniae
ReplyDeleteStreptococcus pneumoniae leads to Pneumococcal Disease. Symptoms may include fever, chills, headache, ear pain, cough, chest pain, disorientation, shortness of breath and occasionally stiff neck. Although anyone can contract the disease, it most commonly occurs in young children, elderly, people with serious underlying medical conditions (chronic lung, heart, or kidney disease), alcoholics, diabetics, and people with sickle cell anemia, HIV/AIDS, or those without a spleen. The disease is spread by airborne or direct exposure to respiratory droplets from a person who is infected or carrying the bacteria. Prompt treatment with penicillin is generally effective. However, people with penicillin-resistant pneumococcal infections require treatment with more powerful antibiotics.
-Gillian Garcia
SARS
ReplyDeleteinfants, children, and old people are most effected.
symptoms: high fever, dry cough, muscle aches, chills& shivering, breathing difficulties.
can be contracted through events such as coughing, saliva, the air, blood, sexual contact, etc. similar to how you contract a cold.
fight it: antiviral medications,high doses of steroids (to reduce lung inflammation), supplemental oxygen
Strep Throat
ReplyDeletesymptoms: pain swallowing, sore throat without coughing, swollen lymph nodes, bright red spots on the roof of the mouth, maybe swollen tonsils
contracted by:streptococcus bacteria. most common to children and adolescents.
treated by antibiotics.
MRSA is a bacterial infection found on the skin. It is often seen in athletes that share equipment. It is contracted when a person has MRSA and an uninfected person comes into contact with the bacteria through open wounds. Treatment depends on the type of infection. For some you need antibiotics, and others a doctor will incise and drain the wound. It can be prevented simply by washing yourself and your equipment properly, and avoiding skin to skin contact if you have an open wound. It starts out looking like a rash, but can become an open, inflamed area on the skin.
ReplyDeleteInfluenza, aka the flu, is a potentionally fatal viral disease. Anyone can get influenza. It is contracted by coming into contact with the influenza virus, whether from an infected person or an infected object. Some symptoms are nausea and vomiting, weakness/fatigue, sore throat, fever, and coughing. There is a vaccine that can prevent influenza, and it can be treated by getting lots of rest, drinking lots of fluids, and sometimes taking certain kinds of drugs.
ReplyDeleteRhino Virus
ReplyDeleteSymptoms include sore throat, runny nose, nasal congestion, sneezing and cough; sometimes accompanied by muscle aches, fatigue, malaise, headache, muscle weakness, or loss of appetite.
The disease is world-wide.
You can contract it from person to person through inhalation ect..
To prevent it you should wash your hands often and take any the usual cold preventative measures.
THe H1N1 more commonly known as Swine Flue:
ReplyDeleteSymptoms may include: ● Fever ● Cough ● Sore Throat ● Runny Nose ● Body Aches ● Headaches ● Chills ● Fatigue ● Runny Nose
adults 65 and older, young children, pregnant women, and people with certain chronic medical conditions are more susceptible to this disease.
For protection:
Cover your nose and mouth with a tissue when you cough or sneeze.
Throw the tissue in the trash after you use it.
Wash your hands often with soap and water, especially after you cough
or sneeze. If soap and water are not available, alcohol-based hand
cleaners are also effective.
Avoid touching your eyes, nose or mouth to avoid contracting illness.
Try to avoid close contact with sick people.
Practice good health habits including getting enough sleep, eating
nutritious foods, and exercising regularly.

E. Coli is a bacteria that exists naturally in warm-blooded organisms, but can contaminate a food supply and cause many harmful effects to one's body.
ReplyDeleteSymptoms: diarrhea, fever, UTI, death (from combinations of illnesses)
It can be spread by improper and unsanitary food packaging and preparation.
People who live in unsanitary conditions and areas are most susceptible.
Best method of prevention is proper food preparation.
Anthrax is a deadly bacteria that can enter one's body through an open wound/sore, or even through contaminated animal products.
ReplyDeleteSymptoms: abnormal breathing, damage to the tissues in various organs, internal bleeding, and even death.
The people most susecptible to anthrax are those that could be targeted, (terrorism/chemical warfare) and people who live in areas where contamination can occur in animal products.
Prevention includes early detection of contaminated products, and vaccines/antibiotics to those who could be harmed.

Symptoms: Poor appetite, fever, headaches, lethargy, generalized aches and pains, diarrhea, chest congestion and abdominal pain.
The bacteria, Salmonella typhi which cause typhoid, are deposited in water or food by a human carrier and are then spread to other people in the area. Fatality is 33%, but with antibiotics, care, and mortality can lower the rate by 1%-3%. Pretty much anyone can contract it if they consume the contaminated water or food.

ReplyDeleteI did mine on Mad Cow Disease
Mad cow disease, which is scientifically known as 'Bovine Spongiform Encephalopathy' (BSE), is an ailment that affects the central nervous system of cattle. This dangerous disease can also be found in human beings and is known as variant Creutzfeldt-Jacob disease (vCJD). The name is taken from the names of the two physicians who discovered the existence of this disease.
***Noticeable effects in humans don't show until 2-8 years***
-The earliest symptoms of mad cow disease in humans include depression, insomnia and anxiety. The person may look withdrawn and seem to be always in a confused state of mind. One would be able to notice significant changes in the personality and behavior of the individual. He/she may also experience muscle spasms, i.e. involuntary muscle contractions that are very painful.
-As the condition of the person suffering from mad cow disease worsens, he/she loses muscle control and coordination, and may also face some problems involving vision and memory. He/she may start having a blurred vision, and also start forgetting people and things that they do in their daily life. It is also usual to experience a tingling sensation on the feet, hands, face and legs of the individual who has mad cow disease.
-As the condition of the patient worsens, he may develop dementia and all his mental and physical functions will become weak. During the final stages of the ailment, the patient may go into a coma which finally leads to death. A person reaches the final stage within 6 months to one year after the inception of the symptoms.

ReplyDeleteMy next one is the staph infection MRSA
Staph skin infections, including MRSA, generally start as small red bumps that resemble pimples, boils or spider bites. These can quickly turn into deep, painful abscesses that require surgical draining. Sometimes the bacteria remain confined to the skin. But they can also burrow deep into the body, causing potentially life-threatening infections in bones, joints, surgical wounds, the bloodstream, heart valves and lungs.
smallpox
ReplyDeletesymptomes- at first, cold-like symptoms, then a rash around the mouth area that soon spreads to the rest of the body, developing into large boil like things that usually have a 'dimple' in the center.
cause- through the air.
who- pretty much anyone who comes into contact with the virus. even with a vaccination, smallpox is still contractable with its more severe strings.
fight- the best method is to get vaccinated. but if you dont, or catch the virus anyway, there are treatments that range from antibiotics to viral insolation.

Symptoms: Mucus buildup in your nose
Difficulty breathing through your nose
Swelling of your sinuses
Sneezing
Sore throat
Cough
Headache.
Most Affected: people with the common cold
Contracted by: Inhaling the virus through moisture in the environment
How to fight the hazard: Antibiotics, alot of vitamin c, & getting rest
anthrax
ReplyDeletesymptoms- fever, flu-like symptoms, cough, sores, especially on your face, arms or hands, that start as a raised bump and develops into a painless ulcer with a black area in the center.
who- pretty much everyone who comes into contact with the spores.
how- anthrax develops as spores and can be absorbed through the skin, inhaled, or ingestion, each producing a different string of the disease.
treatment- early response is cruical. mostly doctors can help you if you hurry to get help. inhalation is usually fatal. gastrointestinal is fatal to about 20-25% of people with skin absorbtion killing about 20% of infected individuals.
fun fact- anthrax is NOT contagious from person to person.
