Infectious diseases

Introduction Do infectious diseases pose a big global health threat? Infectious diseases have been around for centuries and each year we discover new outbreaks around the world. One of our primary goals in global health is to prevent the spread of disease by adopting new technologies and providing primary prevention health education to ensure people live a prolonged life. Communicable diseases such as foodborne diseases do not only spread within a country, but can also easily transcend borders through international trade and travel (Philpott, 2015). There are an estimated thirteen million people who die each year from an infectious or parasitic disease (WHO, 2016a). The World Health Organization (WHO) (2016a) states that in developing countries…

CHAPTER 1 INTRODUCTION 1.1 TUBERCULOSIS Tuberculosis (TB) is an infectious disease caused by the bacillus Mycobacterium tuberculosis. TB is a major global health problem and it ranks alongside Human Immunodeficiency Virus (HIV) as a leading cause of death worldwide. According to the estimates of WHO global tuberculosis report of 2015, there were 9.6 million people who developed TB and 1.5 million who died from the disease in 2014. 1.2 TRANSMISSION AND PATHOGENESIS OF TB TB infection occurs when…

“You can find bacteria everywhere. They 're invisible to us. I 've never seen a bacterium, except under a microscope. They 're so small, we don 't see them, but they are everywhere” (Bonnie Bassler). Pathogens can be found all around us. Over 160,000 people die each year in the United States from infectious diseases that Pathogens cause. Pathogens can be traced from decades ago even during the geologic time. Many pathogenic organisms show ancestral traces in the fossil records from hundreds of…

chronic infectious disease of the supporting tissues of the teeth. Due to bacterial infection, periodontal tissues become inflamed, and are slowly destroyed by the action of the inflammatory process. If the disease is left untreated, teeth lose their ligamentous support to the alveolar bone, alveolar bone itself is resorbed, and the teeth become mobile and are finally lost.1 Traditionally, periodontitis was thought to be strictly environmental in origin. Despite this belief, it was recognized…

Over the past years, scientists from different fields, extending from medicine and biology to applied mathematics and computer science, have teamed up to assess emerging diseases. Mathematical modelling plays an important role in predicting, forecasting and controlling disease outbreaks. Despite control measures, it often happens that outbreaks remain a serious public health risk in areas where recurrent outbreaks have been observed for a long time. Therefore, it is crucial to evaluate the…

Infection is called as a pathogen invades a human or an animal and grows in the organism, and the expression of symptoms caused by this infection is called infectious disease. Infectious diseases have no symptoms at all, but it has incurable infection that cause only immunity, and those that cause symptoms. Sometimes they are synonymous with infectious diseases. Infectious is a disease that easily migrates to many people. In Europe, there are many programs to cure and prevent the infectious…

Statistics about infectious disease, still a leading killer in the world 1. Despite new technology and prosperity, still a main threat 2. People believe it is a problem of the past, but it is not B. By mid-20th century most experts had declared the war against infectious diseases was over 1. Overly optimistic, infectious diseases have been reemerging 2. Complacency followed and it is a shock how devastating infectious diseases have been since the start of the 21st century 3. Many new diseases…

The death of an elderly man on a flight from Beijing to Brisbane has been brought to our attention, as it appears the death was the result of an infectious disease, which we believe may have been ‘severe acute respiratory syndrome’ (SARS). SARS is a respiratory illness produced by a coronavirus, called ‘SARS-associated coronavirus (SARS-CoV). It was first identified in 2002 in southern China, which resulted in an epidemic in 37 countries, with more than 8000 cases and 774 deaths. The epidemic…

Certification in Basic Infectious Disease I chose to receive a certification on the material of Basic Infectious Diseases because I plan on going into the medical field. I am not overly educated with epidemiology, so I wanted to increase my knowledge in relation to this subject. I believe it will help with basic information that I will need to know as a nurse. I also chose this topic because this certificate only required around an hour of my time, which was rewarding in the content provided,…

Health care organizations are extremely thorough when it comes to the risk management program. Because there is much vulnerability for the spread of infectious diseases within a health care facility, the risk management team have to pay close attention and develop many strategies toward the prevention of this risk. Alliance Health Center (AHC) maintains full awareness of the risks within its facility; therefore, through careful research and interview sessions with some of the health care…
