Viruses And Diseases
A virus is a tiny infectious agent that can only replicate when inside another organism's cells. Viruses will infect any type of organisms, animals, plants, human beings all included. Some of the common diseases caused by viruses include influenza, cold sores, chicken pox, and the common cold, while more serious and life threatening cases include the more prevalent AIDS, ebola, avian flu, SARS, swine flu to name but a few. The ability of a virus to cause disease is depicted in terms of its virulence.
There are some diseases however which are still under research to determine whether they are caused by viruses or not, a perfect example being the likely connection between neurological diseases like chronic fatigue syndrome and multiple sclerosis and the human herpes virus 6 (HHV6). Still on point, alarming debate is going on whether the borna virus, which was previously suspected to be the causative agent of neurological diseases in horses, could be the culprit behind psychiatric conditions in humans.
Generally, viruses have diverse mechanisms in which they cause a disease in a living organism, which basically depends on the viral species in question. At the cellular level, mechanisms simply include cell lysis i.e. breaking open and ensuing death of the cell. When dealing with multicelluar organisms, effect can only be felt when all cells die in the entire organism. While a virus will typically disrupt the normal functioning of the body to cause diseases, some can still exist fairly harmless in an organism.
A perfect example of this is the herpes simplex virus, known to cause sores. It is able to remain in a dormant state in the human body. While they can eventually cause diseases, there presence can sometimes be beneficial as the mere presence of it can increase the body's immunity against pathogenic infections like Yersinia Pestis. Note however that some viruses are known to cause chronic or life-long infections, in cases where the virus continues to replicate inside the body regardless of the body's defense mechanism.
This is evident in hepatitis B and C virus infections. In such cases, individuals who are chronically infected are known as carriers as they act as stores of infectious viruses. In a society where many people are carriers, the disease will be termed as endemic. Virologists, the people who study viruses and their behaviors, are however always trying to identify the different viruses so that vaccination and treatment against them can be discovered.

Water Borne Diseases
Water Borne Diseases
Water borne diseases are caused by drinking water which is contaminated. The main causes of contamination are human and animal waste as well as disease-causing microorganisms. These diseases can easily be treated in case they are diagnosed early enough. One should go for regular check-ups in case they are often exposed to contaminated drinking water.
Some water-borne diseases like cholera are known to have existed for a very long time. Others are very new and few people have heard or suffered from them. In the case of new diseases, it is important that diagnosis be carried out first before treatment can be done.
Water borne diseases outbreaks occur when there is a lot of contaminated water in the wrong places. It is important for one to understand the ecology of water-borne diseases in order to understand their transmission, cure and prevention measures.
The situation in developing countries is worth mentioning when it comes to water-borne diseases. Four fifths of all diseases that are reported in these countries are water-borne. In fact, diarrhea is the single leading cause of death among children in these countries.
The main reason why people suffer from these diseases is lack of clean, reliable water for drinking and cooking. Poor sanitation is a problem to 1.1 billion people in the world, who have no access to reliable water supply.
It is also important for people all over the world to understand how water-borne diseases are transmitted. In case the problem of water-borne diseases is to be overcome, pollution of water systems must be prevented at all costs. Drinking water must be kept clean all the time. Infected people must be taken care of in a hygienic manner in order to prevent transmission to a wide section of the population.
When septic tanks burst, it can cause a catastrophe, and a large section of the neighboring population might end up getting infected. This is why sewer treatment plants should be located away from residential areas. Manufacturing plants that throw waste into rivers are a major cause of water-borne diseases.
Outbreaks of water-borne diseases can be very dynamic. You always have to be vigilant especially if you live in an area where typhoid and cholera outbreaks are frequently reported. You should refrain from buying food that has been cooked in unhygienic conditions. It takes little effort to ensure that the water that you are drinking is clean and free from any disease-causing microorganisms. If you suspect to have been infected, it is good to go for a medical examination.

Skin Diseases Symptoms
Skin Diseases Symptoms
A skin disease is a condition which involves the largest organ in the body - the skin. The fact that the skin is largely exposed makes it more susceptible to diseases and symptoms. Still on point, as it is a highly visible organ, the symptoms of skin diseases are mostly identified early by keen patients who pay attention and take note of the changes in the skin. Unfortunately, skin diseases can be a source of embarrassment and humiliation, thanks to its extremely visible nature.
Skin diseases can be acquired or congenital. Acquired skin diseases are those that target the skin superficially and are mostly caused by fungi and bacteria such as impetigo that affects the face and athlete's foot that affects people in between their toes. Acquired skin diseases are treatable with topical application of medications. Allergic reactions, contact with irritating substances, and insect bites can also cause skin diseases.
Congenital diseases on the other hand are genetic in nature, a perfect example being Harlequin ichthyosis, an extremely painful skin disease whose symptoms include scaling of the skin, blistering, and discoloration. To manage such a disease one would need to be very comfortable and the symptoms should be dealt with as the disease may be incurable.
Other causes of skin diseases, which may reflect underlying medical complications include eczema, hives etc. skin diseases can also be caused by nutritional deficiencies, hormonal imbalances, prolonged exposure to UV rays, stress etc. depending on the nature of your disease, skin disease symptoms have different manifestations. First symptom is that the skin tends to change the color as well as the texture, it become hot, slimy to touch, and swollen.
Embarrassing symptoms of skin diseases include acne, chiggers, lichens, cysts, rosacia, boils, psoriasis etc resulting in symptoms such as itching, swelling, redness, irritation, etc. Every skin disease is characterized by its own distinct symptoms, in addition to the common symptoms that generally affect all skin diseases. It is however easy to identify a skin disease because it will change the appearance of the skin and as mentioned cause irritation.
Many skin diseases are generally identified by simply their appearances as well as their symptoms, although there are still other conditions that will call for a blood test for proper diagnosis and right treatment to be administered. This is particularly important because most skin diseases are cyclic in nature hence right diagnosis is needed if they are ever to disappear completely.

List Of Communicable Diseases
List Of Communicable Diseases
Most states in the United States have specific laws and guidelines that spell out how communicable diseases should be kept in check and how outbreaks should be curbed. Towards this end, they keep a list of communicable diseases that is available even for the general public. The list communicable diseases is primarily used by the health facilities, healthcare providers and the relevant monitory authorities to ensure that such diseases are kept under control at all times.
Basically a diseases is termed communicable (CD) if it is infectious and can be transmitted from a sick person to a healthy person via direct contact, contact or exchange of bodily fluids, or even through an indirect contact (like touching something that's bee touched by an infected person). The following list of communicable diseases has been classified into some basic categories that overlap. Attempt has been made to build the list accumulatively, such that no disease is repeated if it occurs in more than one category.
Some common communicable diseases among children in the US include HIV/AIDS, bacterial meningitis, pink eye, fifth disease, cold sores (herpes simplex), viral hepatitis (A, B and C), lice, flu, mumps, measles, mono (mononucleosis), pinworms, whooping cough, RSV (respiratory syncytial virus), German measles (rubella), rosella, scabies, ringworm, staph infections, Chlamydia, genital herpes, scarlet fever, strep throat and tuberculosis.
Besides these, the EU has several other infections identified on its list of communicable diseases. Such diseases (Not covered above) include Amebiasis, Babesiosis, Chancroid, Chlamydia, Chickenpox (Varicella), Clostridium Difficile Infection, Crabs, E Coli, Eastern Equine Encephalitis (EEE), Ehrlichiosis, Giardiasis, Herpes, Hib/Haemophilus Influenza Type B, HIV, Human Papillomavirus (Genital Warts), Influenza, Legionellosis, Lyme, Meningitis (Meningococcal Disease), Molluscum Contagiosum, MRSA, Nongonococcal Urethritis (NGU), Norovirus Infection, Pediculosis and Pelvic Inflammatory Disease (PID).
In additions to these, both the EU and US recognize the following as communicable diseases; Pertussis (Whooping Cough), Polio, Rabies, Rocky Mountain Spotted Fever, Salmonellosis, Shigellosis, Brucellosis, Echinococcosis, Scabies, Streptococcal and West Nile Virus. Some common sexually diseases across the continents include Gonorrhea, Chlamydia infections, Gonococcal infections, HIV-infection and Syphilis
In sub-Saharan Africa, there are some communicable diseases that are regarded as serious imported diseases and they include Cholera, Malaria, Plague and Viral hemorrhagic fevers. The most notorious communicable diseases that are airborne include Legionellosism, Meningococcal disease, Pneumococcal infections and Tuberculosis.
Some common food and water-borne communicable diseases and other diseases with an environmental origin include Botulism, Campylobacteriosis, Cryptosporidiosis, Giardiasis, Enterohaemorrhagic E.coli, Leptospirosis, Listeriosis, Toxoplasmosis, Trichinosis and Yersinosis.

List Of Diseases
List Of Diseases
Humanity has experienced throughout the history many kinds of deadly diseases that have shaken up the medical systems. Scientists had tried to develop theories in order to find treatments to prevent the appearance and if possible to cure some of the deadliest illnesses that affected millions of human beings. Diseases like cancer, AIDS or cardiovascular problems cause the death of hundreds of people every year worldwide. The top four dangerous diseases are described below:
Heart disease affects heart muscles and is considered to be the primary cause of death among adults. It includes symptoms such as irregular and rapid heartbeats, exhaustion, chest pains, difficulties when breathing or dizziness. The causes may vary from smoking, inappropriate foods, diabetes, lack of exercises to heredity. Medicines help affected people get better by improving the heart condition but they cannot restore the health. A proper treatment and a healthy lifestyle may help patients live with the disease for many years.
Cancer is the second cause of death among people. In all its forms, it has killed hundreds of people yearly. Cancer affects many parts of the human body. The most common forms are breast cancer, skin and colon cancer. Leukaemia, known as blood cancer is described as abnormal multiplication of white blood cells. When treating it, it's important for doctors to know the patient's medical history. The procedures are complicated and often hurtful ranging from surgery, radiotherapy, chemotherapy to immunotherapy.
AIDS also known as Acquired Immune Deficiency Syndrome is the advanced form of HIV (Human Immunodeficiency Virus). This virus attacks the immune white cells also called CD4, which act in order to protect the human body from illnesses. When the immune system looses too many Cd4 cells, the human body gets very week and can't fight against infections which finally kill the patient.
People with HIV can live many years without knowing it but HIV can develop AIDS if no proper treatment is administrated. Death occurs when a deadly infection installs in the weakened body which can no longer survive.
Diabetes is also a well known chronic disease which affects thousands of people around the world. It causes heart strokes, kidney diseases, infections due to high blood glucose which attacks blood vessels. There are three forms of diabetes: type 1 is the insulin dependent diabetes affecting mostly teenagers and children. Treatment implies taking insulin, lots of exercises and strict diets. Type 2 affects people of all ages. This type of diabetes makes pancreas not to secrete the needed insulin. Overweight people are likely to develop this kind of diabetes. The third type is the gestational diabetes which appears at pregnancy.
Diseases such typhus, cholera or malaria have horrified the humanity throughout old times by killing millions of people. Scientists take enormous efforts to discover treatments for which are now incurable diseases. Dealing with an illness it's not all about the treatment. Prevention is the key. Yet, maybe the worse of all is denial and indifference regarding our body.

Immune System Diseases
Immune System Diseases
Immune system diseases can be put into two general classifications: There are disorders or diseases of the immune system where the body ceases to have the defenses necessary to fight off disease, and the other disorder is where the body overly reacts to stimulus, which consequently results in organ damage and function.
There are multiple rare genetically inherited disease processes of the immune system that are classified as primary immune deficiency disorders. These disorders affect about fifty thousand people within the United States, alone.
A person with a healthy immune system has the physiological ability to identify invading viruses, bacteria or any element that is not a typical part of the body's function and destroys them.
In cases of immune system diseases where there exists a debilitation in the response, frequent infections occur within the victim. The most Common disease that occurs in people as a result of a lower functioning immune system is AIDS.
AIDS is not inherited or caused at birth. It is caused by becoming infected with the HIV (Human Immune Deficiency Virus) by way of blood transfusion, sexual intercourse and IV drug usage.
The HIV virus invades the T-helper cells in the body that are responsible for destroying invaders by creating anti-bodies, but when this system is compromised by HIV, the process ultimately destroys the bodies immune system causing numerous infections, including cancer and pneumonia- and without drug treatment- even death.
Currently there are over 955,000 people with AIDS in the United States. This disease is acquired, which means that people who have become infected had normal, healthy immune systems to start with.
Other immune system diseases include allergies, Addison's disease, Rheumatoid Arthritis, Lupus, Psoriasis and Multiple Sclerosis.
Immune disorders like Lupus and Rheumatoid Arthritis are believed to be caused by an over-reactive immune system.
Much research has been done on the study of immune system diseases, treatments, prevention and cures.
As of today, many alternative health care industries who promote dietary supplements and herbs have concluded that maintaining a healthy immunes system is possible by boosting the body's ability to fight off infection by a healthy diet, exercise, and taking these nutrients on a daily basis.
There are also a number of research scientists currently doing studies on drugs that can be used to treat these immune system diseases, particularly with the epidemic of AIDS that has infected almost a million Americans to date.

Diseases Caused By Virus
Diseases Caused By Virus
Viruses have been in existence since time immemorial, as early as the 1800s, although virologists could not identify them positively during the 1800s, proper identification took place in the 1900s with advancement in technology. The virus word originates from a Latin word meaning a poison or toxin. Perfect examples of viruses include Marburg, influenza, HIV, and Ebola to mention but a few. Majority of these viruses are well-known for their virulence and are disgracefully hard to treat because they mutate faster and quite effectively.
A virus cannot survive or reproduce on its own, it would need a host so that it can pass on its genes. Typically, the particle of a virus will consist of a protein cover which contains all the genetic material of a virus. This explains the reason why virologists today are reluctant to categorize viruses as living organisms. Still on point, another reason why it is so difficult to classify viruses is because of their unique behavior that is different from any other form of life today.
Some of the common diseases that are caused by virus include:
- AIDS
- Colorado tick fever
- Burkitt's lymphoma

Common Childhood Diseases
Common Childhood Diseases
Children are usually vaccinated from birth against various common childhood diseases. Most can be contagious while others are not. Contagious diseases are transmitted one to another, in environments such as day-care centers, classrooms, and common play areas.
Many common childhood diseases, once contracted could result in lifelong immunity in the infected child. Vaccinations provide immunity to some diseases.
Parenting is no easy task and it is when these precious bundles of joy get sick that parents get worried and want to do their best and work wonders to make the pain and discomfort go away. This is not always possible, and contracting any of the common childhood disease can be possible at any time and age.
Here is a list of common childhood disease.
Chickenpox - once contracted the body is immune to a further attack at a later stage or age. Symptoms include, red, itchy, spots or blisters that is scattered throughout body. The child may have a slight fever. Treatment could be in the form of calamine lotion to reduce itching. Antiviral medicine if the outbreak if severe and some mild medication for the fever may be administered. Incubation period would usually be between 10 - 20 days. Chickenpox can be considered contagious from a few days before and after the disease. The child should not attend school. Plenty of fluids should be included in the normal diet. In some cases antibiotics would be prescribed.
Whooping cough - symptoms include fits of coughing, wheezy breathing and vomiting. Symptoms may become worse and flare up at night. There is no particular treatment; children should be given small amounts of food to prevent vomiting and plenty of fresh air. Incubation period would usually be 7 days after exposure. The disease is contagious during the first week. The child should be kept away from school.
Viral infection - Symptoms include rash, fever, muscle aches and headache. It is also know as "slapped cheek" syndrome. Treatment should be sought if the symptoms are severe and the child in uncomfortable. Incubation period is up to 14 days and is mostly seen in children between the ages of 4 and 12.
Strep Throat - the child will have a sore and red throat with symptoms including vomiting, headache, fever and abdominal pain.
