Types Of Diseases Causes Of Diseases Prevention Introduction Viral diseases Bacterial diseases

PowerPoint Presentation:

Why Do We Fall ILL??? Some diseases are caused by bacteria and some , such as AIDS and the common cold, are caused by viruses. Normally, our immune system protects us against diseases. But sometimes our body – because of too little sleep or a lot of stress- becomes so weak that the immune system does not work properly and we succumb to diseases. Luckily, we can get ourselves vaccinated against some dangerous diseases .

PowerPoint Presentation:

Health : It is a state of being well enough to function well physically, mentally and socially. Illness : Illness and sickness are generally used as synonyms for disease . However, this term is occasionally used to refer specifically to the patient's personal experience of their disease. In this model, it is possible for a person to be diseased without being ill. Illness is often not due to infection but a collection of evolved responses, sickness behavior by the body which aids the clearing of infection. next

PowerPoint Presentation:

Other contents Types Of Diseases Infectious Disease : Diseases where microbes are the immediate cause. Contagious diseases : A subset of infectious diseases. Communicable diseases : Diseases which spread through an infected person to a healthy person through air, water, contaminated food and pathogens . Airborne diseases : A disease that spread from air . Non-communicable diseases : It is a medical condition or disease which by definition is non-infectious and non-transmissible between persons. Lifestyle diseases : Diseases that appear to increase in frequency as countries become more industrialized and people live longer .

Causes Of Diseases:

Causes Of Diseases Let us look at an example. If there is a baby suffering from loose motions ,we can say that the cause of loose motions is an infection with a virus. So the immediate cause of the disease is a VIRUS . Virus could have been come through unclean drinking water. But in some cases one baby develops loose motions while the other baby does not ? The reason could be that the baby is not HEALTHY .As a result, it might be more likely to have diseases when exposed to risk, whereas healthier babies would not.

PowerPoint Presentation:

Lack of Good Nourishment : The baby is not healthy because it is not well nourished and does not get enough food . So, this is the another cause . Genetic Difference : It is also possible that the baby has some genetic difference that makes it more likely to suffer from loose motions when exposed to such a virus . Without the virus , the genetic difference or the poor nourishment alone would not lead to loose motions .But they do become contributory causes of the diseases. Other contents

A cure is the end of a medical condition or a treatment that is very likely to end it, while remission refers to the disappearance, possibly temporarily, of symptoms. Complete remission is the best possible outcome for incurable diseases. CURE : PREVENTION : Many diseases and disorders can be prevented through a variety of means. These include sanitation, proper nutrition, adequate exercise, vaccinations, and other self-care and public health measures.

PowerPoint Presentation:

Medical therapies or treatments are efforts to cure or improve a disease or other health problem. In the medical field, therapy is synonymous with the word treatment . Treatments may be provided by an organized health care system, or informally, by the patient or family members. A prevention or preventive therapy is a way to avoid an injury, sickness, or disease in the first place. A treatment or cure is applied after a medical problem has already started. A treatment attempts to improve or remove a problem, but treatments may not produce permanent cures, especially in chronic diseases. Fact file T r e a t m e n t

PowerPoint Presentation:

How can we prevent Diseases? There are two ways, one general and one specific to each diseases . The general ways of preventing infections mostly relate to preventing exposure. How can we prevent exposure to infectious microbes? For airborne microbes , we can prevent exposure by providing living conditions that are not overcrowded . For waterborne microbes, we can prevent exposure by providing safe drinking water . This can be done by treating the water to kill any microbial contamination . For vector-borne infections , we can provide clean environments . This would not , for example, allow mosquito breeding . In other words , public hygiene is one basic key to the prevention of infectious diseases . Next

PowerPoint Presentation:

Once someone has a disease, their body functions are damaged and may never recover completely. Treatment will take time, which means that someone suffering from a disease is likely to be bedridden for sometime if we can give proper treatment. The person suffering from an infectious disease can serve as a source from where the infection may spread to other people. This leads to the multiplication of the above difficulties. It is because of such reasons that prevention of diseases is better than their cure . Other contents Treatment

This is because the original host may either die or eliminate the infection. Some important routes of viral transfer include: Spread of Viruses

PowerPoint Presentation:

Several antiviral drugs that are used to treat viral infections have been developed over the past two decades. Many of these are focussed against HIV. These do not cure HIV infection but stop the virus from multiplying and prevent the progress of the disease. Another notable antiviral drug is Ribavarin against hepatitis A Viruses in general are notoriously difficult drug targets as they modify and adapt themselves rapidly to build up a resistance against the drug. Case in point is Oseltamivir (trade name - Tamiflu ) used in influenza.

PowerPoint Presentation:

Bacterial diseases include any type of illness caused by bacteria. Bacteria are a type of microorganism, which are tiny forms of life that can only be seen with a microscope. Other types of microorganisms include viruses, some fungi, and some parasites. Millions of bacteria normally live on the skin, in the intestines, and on the genitalia. The vast majority of bacteria do not cause disease, and many bacteria are actually helpful and even necessary for good health. These bacteria are sometimes referred to as “good bacteria” or “healthy bacteria.” What Are Bacterial Diseases?

PowerPoint Presentation:

Symptoms of bacterial diseases vary depending on the type of bacterial infection, the area of the body that is infected, and other factors, such as the patient’s age and health history. The symptoms of bacterial diseases can also resemble symptoms of other diseases, such as colitis, influenza, and viral infections. The classic symptom of a bacterial infection is a Fever , although not all people with a bacterial infection will have a fever. What are the symptoms of bacterial diseases?

PowerPoint Presentation:

What causes bacterial diseases? Bacterial diseases are caused by harmful bacteria (pathogenic bacteria). The vast majority of bacteria do not cause disease, and many bacteria are actually helpful and even necessary for good health. Bacterial diseases occur when pathogenic bacteria get into an area of the body that is normally sterile, such as the bladder, or when they crowd out the helpful bacteria in places such as the intestines, vagina or mouth. Less common, bacterial infections can occur when healthy bacteria multiply uncontrollably.

PowerPoint Presentation:

There are several measures used to quantify the burden imposed by diseases on people. The years of potential life lost (YPLL) is a simple estimate of the number of years that a person's life was shortened due to a disease. For example, if a person dies at the age of 65 from a disease, and would probably have lived until age 80 without that disease, then that disease has caused a loss of 15 years of potential life. + Close YPLL measurements do not account for how disabled a person is before dying, so the measurement treats a person who dies suddenly and a person who died at the same age after decades of illness as equivalent. In 2004, the World Health Organisation calculated that 932 million years of potential life were lost to premature death. In 2004, the World Health Organization calculated that 1.5 billion disability-adjusted life years were lost to disease and injury. FACT FILE
