Infectious disease

infectious disease
An infectious disease is any disease caused by a pathogen (germ) such as a virus, bacteria, parasite, or fungus. Other living organisms such as animals, plants, and microorganisms can all be made ill by an infectious disease.

Pathogens

“Pathogen” is the scientific name for “germ.” Infectious diseases are caused by pathogens. When your mom says to wash your hands because of germs, she wants you to get all the pathogens off your hands so they won’t go into your mouth and body. Pathogens are tiny organisms (called microorganisms) that invade the body and make it
sick. Different kinds of pathogens cause different kinds of diseases. Here are some diseases caused by each type of pathogen:
  • Viruses – Viruses are extremely small and consist of DNA with a protective coating of protein. Diseases caused by viruses include influenza, the common cold, measles, yellow fever, and hepatitis.
  • Bacteria – Bacteria are small microorganisms. They can cause diseases such as tuberculosis, cholera, typhoid fever, and tetanus.
  • Parasites – Parasites are organisms that live off their hosts. Some parasitic diseases include malaria, sleeping sickness, and scabies.
  • Fungi – Fungi are microorganisms such as yeasts and molds. They can cause diseases such as fungal meningitis, ringworm, and thrush.

Transmission

Infectious diseases can be transmitted in several ways including:

  • Food and water contamination – Some diseases are passed on by contaminated food or water. This can occur in undercooked food or when sewage gets into the water supply. Examples of diseases that are transmitted this way include E. coli, cholera, and salmonella.
  • Insect bites – Insects such as fleas, mosquitoes, and ticks can carry pathogens that get passed on when they make contact with humans. Diseases from insects include malaria (mosquitoes), Lyme disease (ticks), and the bubonic plague (fleas).
  • Direct contact – Diseases are often passed from person to person by direct contact. This could include shaking hands, sneezing (airborne), and kissing. Examples include influenza, the common cold, and chickenpox.
  • Indirect contact – Some pathogens can survive for a while outside the host. They may be on objects such as doorknobs and telephones. Many of the same diseases, but not all, that can spread through direct contact can also be spread through indirect contact.

Other Types of Diseases

Not all diseases are infectious diseases. Some other types of diseases include:

  • Autoimmune – An autoimmune disease occurs when the immune system attacks the body. Examples include Type I diabetes and multiple sclerosis.
  • Lifestyle – Lifestyle diseases are caused by the way people live. They can also be a result of people living longer. Examples include Type 2 diabetes, alcoholism, and Alzheimer’s disease.
  • Disorder – A disease is sometimes called a disorder when some part of the body isn’t functioning normally. Often disorders are associated with the brain and are called mental disorders. Examples include eating disorders such as bulimia and mental disorders such as depression.
  • Heart disease – Heart disease is used to describe anything that is wrong with the cardiovascular system. This includes diseases such as coronary artery disease, high blood pressure, and congenital heart disease.
  • Medical condition – The term medical condition is used to describe everything from injuries to infectious diseases to disorders. An injury such as a concussion would be considered a medical condition.

Interesting Facts about Infectious Disease

  • A Zoonotic disease is an infectious disease that can be transmitted between animals to humans.
  • Not all infections are considered diseases as some infections don’t make a person sick.
  • Not all viruses, bacteria, parasites, and fungi are bad for humans, but the ones that do cause disease are called pathogens.
  • Over 160,000 people die each year in the United States from infectious diseases.
  • A “contagious” disease is an infectious disease that is very easily transmitted.

Ecology

Ecology

Ecology is the study of environmental systems, or as it is sometimes called, the economy of nature. “Environment” usually means relating to the natural, versus human-made world; the “systems” means that ecology is, by its very nature, not interested in just the components of nature individually but especially in how the parts interact.

The subject matter of ecology is normally divided into following broad categories:

  • Physiological ecology– It deals with the response of single species to environmental conditions such as temperature or light.
  • Population ecology– It usually focuses on the abundance and distribution of individual species and the factors that cause such distribution;
  • Community ecology– It deals with the number of species found at a given location and their interactions; and
  • Ecosystems ecology– deals with the structure and function of the entire suite of microbes, plants, and animals, and their abiotic environment, and how the parts interact to generate the whole. This branch often focuses on the energy and nutrient flows of ecosystems, and when this approach is combined with computer analysis and simulation we often call it systems ecology.
  • Evolutionary ecology– It operates at the physiological or population level, is a rich and dynamic area of ecology focusing on attempting to understand how natural selection developed the structure and function of the organisms and ecosystems at any of these levels.

It is usually considered from the perspective of the specific geographic environment that is being studied a moment: tropical rain forest, temperate grassland, arctic tundra, benthic marine, the entire biosphere, and so on. The subject matter of ecology is the entire natural world, including both the living and the non-living parts.

Biogeography focuses on the observed distribution of plants and animals and the reasons behind it. More recently ecology has included increasingly the human-dominated world of agriculture, grazing lands for domestic animals, cities, and even industrial parks.

Industrial ecology is a discipline that has recently been developed, especially in Europe, where the objective is to follow the energy and material use throughout the process of, e.g., making an automobile with the objective of attempting to improve the material and energy efficiency of manufacturing. For any of these levels or approaches there are some scientists that focus on theoretical ecology, which attempts to derive or apply theoretical or sometimes mathematical reasons and generalities for what is observed in nature, and empirical ecology, which is concerned principally with measurement. Applied ecology takes what is found from one or both of these approaches and uses it to protect or manage nature in some way. Related to this discipline is conservation biology. Plant, animal, and microbial ecology have obvious foci.

Reasons to study ecology

There are usually four basic reasons given to study and as to why we might want to understand it:

  • First, since all of us live to some degree in a natural or at least partly natural ecosystem, then considerable pleasure can be derived by studying the environment around us. Just as one might learn to appreciate art better through an art history course so too might one appreciate more the nature around us with a better understanding.
  • Second, human economies are in large part based on the exploitation and management of nature. Applied ecology is used every day in forestry, fisheries, range management, agriculture, and so on to provide us with the food and fiber we need.
  • Third, human societies can often be understood very clearly from ecological perspectives as we study, for example, the population dynamics (demography) of our own species, the food and fossil energy flowing through our society.
  • Fourth, humans appear to be changing aspects of the global environment in many ways.

It can be very useful to help us understand what these changes are, what the implications might be for various ecosystems, and how we might intervene in either human economies or in nature to try to mitigate or otherwise alter these changes. There are many professional ecologists, who believe that these apparent changes from human activities have the potential to generate enormous harm to both natural ecosystems and human economies. Understanding, predicting and adapting to these issues could be the most important of all possible issue for humans to deal with.

army navy air force

The Indian Armed Forces are the military forces of the Republic of India. It consists of four professional uniformed services: the Indian Army, Indian Navy, Indian Air Force and Indian Coast Guard. Additionally, the Indian Armed Forces are supported by several paramilitary organisations (Assam Rifles and Special Frontier Force) and various inter-service institutions such as the Strategic Forces Command. The President of India is the Supreme Commander of the Indian Armed Forces. The Indian Armed Forces are under the management of the Ministry of Defence (MoD), which is led by the Union Cabinet Minister of Defense. With strength of over 1.3 million active personnel, it is world’s 3rd largest military forceand the largest standing volunteer army in the world.

The headquarters of the Indian Armed Forces is in New Delhi, the capital city of India.  India honours its armed forces and military personnel annually on Armed Forces Flag Day, 7 December. The Indian Armed Forces are the world’s largest arms importer, with Russia, Israel, and to some extent, France and United States being the primary foreign suppliers of military equipment.

The Armed Forces have six main tasks;

  • To assert the territorial integrity of India.
  • To defend the country if attacked by a foreign nation.
  • To send own amphibious warfare equipment to take the battle to enemy shores.
  • To follow the Cold Start doctrine, meaning that the Indian Armed Forces are able to quickly mobilise and take offensive actions without crossing the enemy’s nuclear-use threshold.
  •  To support the civil community in case of disasters (e.g. flooding).
  • To participate in United Nations peacekeeping operations in consonance with India’s commitment to the United Nations Charter.

Indian Army : The basic responsibility of the Army is to safeguard the territorial integrity of the nation against external aggression. The force is headed by the Chief of Army Staff of the Indian Army. The Indian Army has seen military action during the First Kashmir War, Operation Polo, the Sino-Indian War, the Second Kashmir War, the Indo-Pakistani War of 1971, the Sri Lankan Civil War and the Kargil War. The Indian army has dedicated one brigade of troops to the UN’s standby arrangements. The Army is often required to assist the civil administration during internal security disturbances and in the maintenance of law and order, in organising relief operations during natural calamities like floods, earthquakes and cyclones and in the maintenance of essential services.

Indian Navy : The foundation of the modern Indian Navy was laid in the seventeenth century when the East India Company had established a maritime force, thereby graduating in time to the establishment of the Royal Indian Navy in 1934. With 58,350 men and women, including 7,000 personnel of Indian naval air arm, 1,200 Marine Commandos (MARCOS) and 1,000 personnel of the Sagar Prahari Bal, it is one of the world’s largest navy. The navy is under the command of the Chief of the naval staff – an Admiral. The Indian navy is deployed under three area commands, each headed by a flag officer. In recent years, the Indian Navy has undergone extensive modernization and expansion with an intention to increase its capabilities as a recognized blue-water navy. It is also only one of the six navies in the world that has nuclear capabilities. In addition it is in command of the BrahMos which is the fastest cruise missile in the world with speeds of 2.8 Mach.

Indian Airforce :  The Indian Air Force (IAF) today, having completed more than six decades of dedicated service to the nation, is a modern, technology-intensive force distinguished by its commitment to excellence and professionalism. The Indian Air Force was officially established on 8th October 1932, and on 1st April 1954. With the passage of time, the Indian Air Force undertook massive upgrading of its aircraft and equipments. In recent times however, India has manufactured its own aircraft, including the HAL Tejas, a 4th generation fighter, and the HAL Dhruv, a multi-role helicopter, which has been exported to several countries, including Israel, Burma, Nepal and Ecuador. India also maintains UAV squadrons which can be used to carry out ground attacks and aerial surveillance.

Indian Coast Guard : The Coast Guard (CG) was set up as an Armed Force of the Union in 1978 on recommendations of Rustamji Committee for preservation and protection of our Exclusive Economic Zone (EEZ). The CG is responsible for keeping India’s EEZ measuring over 2.02 million sq. kms. under regular surveillance in order to prevent poaching/ smuggling and other illegal activities in the EEZ. The coast guard works closely with the Indian Navy and the Indian Customs Department, and is usually headed by a naval officer of the rank of Vice-Admiral.

The Primary duty of Indian Coast Guard is:

  • To protect our ocean and offshore wealth including Oil, Fish and Minerals.
  • Protect the artificial Islands and off-shore installations.
  • To assist Mariners in distress and safeguard life and property at sea
  • To enforce Maritime Laws with respect to sea, shipping, poaching, smuggling and narcotics.
  • To preserve marine environment and ecology and to protect rare species.
  • To collect scientific data
  • To assist Indian Navy during war situation

The Department of Defence Production of the Ministry of Defence is responsible for the indigenous production of equipment used by the Indian Armed Forces. It comprises the 41 Indian Ordnance Factories under control of the Ordnance Factories Board and 8 Defence PSUs namely, HAL, BEL, BEML, BDL, MDL, GSL, GRSE and Midhani.

The Royal Indian Navy was first established by the British while much of India was under the control of the East India Company. The first Indian to be granted a commission was Sub Lieutenant D. N. Mukherji, who joined the Royal Indian Marine as an engineer officer in 1928.

The major commitments of the Indian Navy constitute patrol missions, anti-piracy operations off the coast of Somalia, the ‘Singapore Indian Maritime Bilateral Exercise’ with the Republic of Singapore Navy in the Straits of Malacca, maintaining a military presence in Southeast Asias waters, and joint exercises with other countries, such as Brazil, South Africa, the United States and Japan, France (Varuna naval exercises), People’s Republic of China, the Russian Navy (INDRA naval exercises)
