The document discusses infectious diseases and how to prevent them. It defines infectious diseases as diseases caused by microorganisms that can be transmitted between individuals. It notes that pathogens cause disease while opportunistic pathogens rarely do so in healthy individuals. There are five major types of infectious agents: bacteria, viruses, fungi, protozoa, and helminths. Some common infectious diseases are listed. Signs and symptoms of infection include fever, cough, sore throat, and others. Hygienic habits like handwashing, vaccinations, safe food preparation, and not sharing personal items can help prevent the spread of infectious diseases.

Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It most commonly affects the lungs but can affect other parts of the body. The disease spreads through airborne droplets when infected people cough, sneeze or speak. Diagnosis involves medical history, physical exam, tuberculin skin test, chest x-ray and microbiological tests. Treatment requires a combination of antibiotics taken for at least 6-12 months to prevent drug resistance from developing. Prevention strategies include identifying infected individuals and their contacts, testing high-risk groups, and immunizing infants with the BCG vaccine.Tuberculosis

Tuberculosis is a bacterial infection that primarily affects the lungs. It is caused by Mycobacterium tuberculosis bacteria and is spread through inhaling droplets from the coughs or sneezes of an infected individual. Common symptoms include cough, fever, night sweats, and weight loss. While it usually affects the lungs, TB can infect other organs like the kidneys, spine, and brain. Treatment involves a combination of antibiotics taken for at least 6 months to kill the bacteria and prevent drug resistance.Tuberculosis and it's therapy

Tuberculosis is a deadly infectious disease caused by bacteria that primarily affects the lungs. It spreads through airborne droplets when infected people cough, sneeze or speak. Symptoms include coughing, fever, night sweats and weight loss. Diagnosis involves skin tests, chest x-rays and sputum cultures. Treatment requires taking multiple antibiotics for at least 6 months to cure active cases and prevent latent cases from becoming active. Drug-resistant strains are a growing problem when treatment is not properly followed.Tuberculosis Fernando M. A.

Tuberculosis is an infectious disease usually caused by the Mycobacterium tuberculosis bacteria that typically affects the lungs. It spreads through the air when people with an active infection cough or sneeze. Most infections are asymptomatic and latent, but about 10% of latent infections can develop into the active form of the disease which can be lethal without treatment. Treatment uses antibiotics to kill the bacteria, with isoniazid and rifampicin being most commonly used both alone and in combination for latent and active infections respectively.TUBERCULOSIS

This document provides an overview of tuberculosis (TB), including:
- TB is caused by various Mycobacterium species, most commonly M. tuberculosis. It most often affects the lungs but can spread to other organs.
- Untreated TB can be fatal within 5 years. It is one of the top infectious killers worldwide. Risk factors include living in areas with high TB rates, poor healthcare access, and immunocompromised status.
- M. tuberculosis infects alveolar macrophages and forms lesions called tubercles. The immune response tries to wall off the bacteria in structures called granulomas. Latent TB occurs when infection is controlled, while active TB results if the immune response is overwhelmed.Tuberculosis

The document discusses tuberculosis (TB), a top infectious disease killer worldwide. It notes that South Africa has a high burden of TB. Symptoms of TB include prolonged cough, fever, night sweats, and weight loss. Healthcare workers are at higher risk of TB infection and should take precautions like wearing masks when treating patients. N95 or FFP2 masks help contain the TB germ but masks with valves allow germs to escape. People with latent TB have the germ but no symptoms, while active TB causes illness and is infectious. The document encourages those suspecting TB to seek medical help and complete treatment.CAUSES OF TUBERCULOSIS POWERPOINT

Tuberculosis is an infectious disease usually caused by the bacteria Mycobacterium tuberculosis that generally affects the lungs. It spreads through the air when infected people cough, spit, speak, or sneeze. While it most commonly involves the lungs, causing symptoms like chest pain and coughing, it can also spread to other parts of the body in 15-20% of cases. Proper ventilation, covering coughs, spending time outdoors, and avoiding crowds can help prevent the spread of the disease.Tuberculosis slides

2) TB germs are spread through the air when an infected person coughs, sneezes or laughs, but casual contact is not a risk.
3) There is a difference between TB infection, where germs are present but dormant, and TB disease, where germs are actively multiplying - only those with active disease can spread it.Tuberculosis Made Easy (Everything about it)

Microorganisms can cause disease when they enter the body and find a favorable environment. An infection occurs through a chain of events - a pathogen must have a reservoir, exit the reservoir, be transmitted to a new host, enter through a portal, and find a susceptible host. Breaking any link in the chain can prevent transmission and infection. Common ways to do this include proper hygiene, sterilization, use of antiseptics, vaccination, and strengthening a host's defenses.Host Microorganisms relationship.pptxtso

This document discusses different types of diseases in microbiology. There are four main types: infectious diseases which are caused by microbes like viruses and bacteria; communicable diseases which spread between people; non-communicable diseases which are chronic like cancer and heart disease; and contagious diseases which spread through direct or indirect contact. Infectious diseases can be infectious, acute, chronic, or subclinical. Diseases spread through stages including a reservoir, exit portal, entry portal, and transmission between hosts.Chapter 6 microbe human interaction

An ancient System for holistic health (mental and physical) and wellbeing, is a scientific art of living with harmony (connecting) of mind and body. Although much more ancient than Patanjali, who documented yoga systematically about 2000 years ago, Patanjali is often referred to as the "father of modern yoga."
Yoga postures are commonly depicted in ancient paintings, carvings, and sculptures in almost all civilizations and religions, thus Yoga cant be described as an act of Hinduism. It originated long before any religion on Earth, with the emergence of life on the Planet. All yoga poses are natural, and what is not natural is not yoga; it is油Viyoga.
Besides Vedic Yoga, Hatha, Vinyasa, Ashtanga, Iyengar, Yin, Restorative, Kundalini, Bikram, Sahaj, and Power yoga are some popular types.
Vinyasa油Yoga is the closest form to Vedic Yoga; it is known for its flowing movements, not very rigorous, not too much straining, actions flow with the breath.
Though all yoga may lead to meditation (Dhyan) for your inner upliftment, it is not the same as described in Hinduism for self-liberation.
In Hinduism, different paths of life looking distinct but can be practiced all together, they are: Karma Yoga (selfless action and service), Bhakti Yoga (devotion and love for God or Godly power), Jnana (Gyan) Yoga (gaining knowledge for self-realization through wisdom), Dhyan Yoga (meditation) and Kriya Yoga (optimum utilization of your vital and muscular energy).油

Hygienic Behavior
- 2. According to the World Health Organization (WHO), "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases." Personal hygiene refers to maintaining the body's cleanliness.
- 3. Infectious diseases An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
- 4. 1. Microorganisms that are capable of causing disease are called pathogens. Note: Most microorganisms do not cause disease. In fact, many probably provide some protection against harmful microorganisms 2. A true pathogen is an infectious agent that causes disease in virtually any susceptible host. Opportunistic pathogens are potentially infectious agents that rarely cause disease in individuals with healthy immune systems. 3. The terms "infection" and "disease" are not synonymous. An infection results when a pathogen invades and begins growing within a host. Disease results only if and when, as a consequence of the invasion and growth of a pathogen, tissue function is impaired.
- 5. There are five major types of infectious agents: 1. Bacteria 2. Viruses 3. Fungi 4. Protozoa 5. Helminths 6. In addition, a new class of infectious agents, the prions, has recently been recognized
- 6. TYPES OF INFECTIOUS DISEASES 1. Influenza (flu) 2. Pertussis (whooping cough) 3. Diphtheria 4. Measles 5. Chikenpox 6. Polio 7. Tuberculosis 8. Mumps 9. Hepatitis 10.HIV/AIDS 11.Smallpox
- 7. SIGNS & SYMPTOMS Fever (this is sometimes the only sign of an infection). Chills and sweats. Change in cough or a new cough. Sore throat or new mouth sore. Shortness of breath. Nasal congestion. Stiff neck. Burning or pain with urination. Unusual vaginal discharge or irritation. Increased urination. Redness, soreness, or swelling in any area, including surgical wounds and ports. Diarrhea. Vomiting. Pain in the abdomen or rectum. New onset of pain.
- 8. HOW TO PREVENT INFECTIOUS DISEASES HYGIENIC HABITS Wash your hands Bathing Laundering Get vaccinated Prepare food safely Good diet/nutritious food Excercise Sleep and rest Stay home when ill Practice safe sex Don't share personal items Travel wisely
