Infectious Diseases

Infectious diseases are mainly caused by micro-organisms  like bacteria, viruses, fungi or parasites. some of these organisms  cause diseases. Than any other cause infectious diseases kill more people throughout the world. These infections are mainly caused by germs .we can get infected by touching, eating, drinking or breathing something. Germs can also spread through animal and insect bites, sexual contact. Some of the diseases like measles and chickenpox can also be prevented by vaccines. Hand washing is also a used to prevent infectious diseases.

  These sciences are used to control human health through monitoring and control of zoonotic disease, infectious disease transmitted from non-human animals to humans, food safety, and indirectly through human applications from basic medical research food supply is through livestock health monitoring and treatment, and mental health by keeping pet’s healthy and long living. Veterinary scientists often collaborate with epidemiologists.

 Pediatric infectious diseases are mainly infected in children; specialists are devoted for diagnosis and treatment of children who suffer from infectious diseases. These diseases are mainly caused by bacteria, viruses, fungi, and parasites and treat mild to most severe conditions. A wide range of   and immunologic diseases caused by bacteria, viruses, fungi, and parasites. Pediatric specialist may also understand the unique signs, symptoms, treatments, and outcomes associated with infectious diseases in children.

 Chronic obstructive pulmonary disease and asthma are cause of respiratory symptoms. These affects the organs and tissues that make gas exchange possible in higher organisms, and includes conditions of the upper respiratory tract, trachea, bronchi, bronchioles, alveoli, and the nerves and muscles of breathing. 

  Infection occupy  organism's  in body tissues by diseases causing agents, their reaction of host tissues to these organisms and  toxins  they produce   must be  sufficient  number and virulence to destroy normal tissue, illness  resulting from an infection. Infectious disease was also known as transmissible diseases or communicable disease, the immune system is a host defense system comprising many biological structures and processes   within an organism that protects against diseases. , An immune system identifies a variety of agents, like pathogens, from viruses to parasitic worms and  distinguishes them from organism’s own healthy tissue.

   These  virus spread   was by Aedas mosquito.these viruses cause birth defects in babies by infected pregnant women, symptoms are mild fever, skin rash, conjunctivitis, muscle and joint pain, malaise or headache. These last for 2-7 days this infection was confirmed by laboratory tests on blood or other body fluids, such as urine, saliva or semen. Ebola virus disease (EVD), is commonly called as Ebola hemorrhagic fever (EHF) or Ebola, signs and symptoms typically start between two days and three weeks after contracting the virus with a fever, sore throat, muscular pain and headache then, vomiting, diarrhea and rash usually follow, along with decreased function of the liver and kidneys.   

Epidemiology suggests that examine the causes, pattern, and effects of health and diseases conditions in population. Characteristic the danger factors for being quality and targets for preventive care. The medical specialty  infectious diseases are HIV/AIDS, malaria, infectious disease, pneumococcus.drug-resistant infections.

Sexually transmitted diseases also are named as genital diseases  caused by bacterium, viruses and parasite and will be infected with either Cupid's disease, gonorrhea, chlamydia or endogenous infections, induced infections and also the a lot of usually famous sexually transmitted infections

A microorganism is rarely alone and once an outsized range of microorganism have gathered to create communities, supposed biofilms.. They attach themselves to surfaces, they trigger severe, chronic inflammation, against that each the system and antibiotics area unit impotent. Bacterial pathogens, vibrio cholera are the molecular approaches.

Plant pathology is that the study of diseases in plants caused by pathogens and environmental conditions. Organisms that cause infectious diseases embody fungi, oomycetes, bacteria, viruses, viroid’s, virus like organisms,  phyto plasma, protozoa, nematodes and parasitic plants.  Infectious disease of plant disease include, modeling of infectious diseases in plants. Medicine Dynamics of disease, epidemics, plant pathology

Immune system is a network of cells and chemicals. The cells  within the system have the flexibility to acknowledge one thing as either self or extending the body system that protects the body from foreign substances, cells, and tissues by manufacturing the immunologic response which includes particularly the thymus, spleen, humor nodes, special deposits of animal tissue and lymphocytes together with the B cells and T cells

Vaccine produces immunity from disease and injected through Needle injections, through by mouth or aerosols. Vaccination is an injection of killed organism that produces immunity against that organism in body 

Infection Control in a health care facility is the prevention of the spread of microorganisms from one individual to another individual to prevent these infectious diseases problems frequent hand washing, infection out breaks, water and food in hospital must be maintained.

Communicable diseases  are spread from person to person or through animals .these can be spread through air and transfer from blood or other body fluids like malaria,HIV/AIDS. non communicable diseases are chronic diseases like heart diseases, cancer and diabetes

Methicillin-resistant S aureus(MRSA) is resistant to many antibiotics. Can also cause a variety of problems ranging from  skin infections and sepsis to pneumonia to bloodstream infections. Skin infections and severe infections are mainly caused. Wearing  gloves,  hospitalization trends  can mainly use  for prevention of MRSA.

Diagnosis for infectious diseases is laboratory tests, imaging scans, biopsies, and antibiotics, antifungals are given for treatment of infectious diseases

Some common and preventable diseases diphtheria,  Haemophilus influenza serotype infection, hepatitis B, measles, meningitis, mumps, pertussis, poliomyelitis, rubella, tetanus, tuberculosis, and yellow fever. Some of the vaccines for preventive infectious diseases are, Animal vaccines, cancer vaccines influenza vaccines, etc.

Contagious diseases spread from one person to another person. Cleaning surface areas ,frequent hand washing, sterilization, get  vaccinated are steps to prevent and control  Contagious  Diseases

Patients are cared for in an environment that is safe and clean. . Every interaction in general practice should include a risk assessment of the potential for infection transmission. Hand hygiene, infectious prevention education and training, safe injection practices

 To prevent and control viral hepatitis need to raise awareness of all types of viral hepatitis infections. Vaccines are also used to prevent and infectious precautions in health care and community settings, safer sex and hand washing, safe food and water provide protection against viral hepatitis

Eradication is that the reduction of infectious disease's prevalence within the international host population to zero. Smallpox and rinderpest are the diseases eradicated. Choice of infectious diseases for wipe-out depend on rigorous criteria

The most challenging neurological disorders are viral and immune mediated disorders  of the nervous system. The most common neuroimmune disorder is multiple sclerosis; and HIV is the most common viral infection of the nervous system, Nonepidemic viral infections constitute the majority of infections affecting the nervous system today. Chronic neurologic disease as a sequel to infection is a relatively new and developing area of both pediatric and adult neurology research. Chief among these disorders is the role of postinfectious brain inflammation in epileptogenesis.

Germs can cause infection in human blood and diseases are known  as  blood borne pathogens. The most common and dangerous germs spread through blood within the hospital are viral hepatitis B and hepatitis c virus. These viruses cause infections and liver injury. This virus cause AIDS. Organisms such as bacteria, viruses ,prions, and parasites will be transmitted through blood transfusions.

Acute rheumatic fever is an autoimmune inflammatory develops as a sequel of streptococcal infection .Acute rheumatic fever  is the result of an autoimmune response to pharyngitis caused by infection with group A Streptococcus. The long term damage to cardiac valves caused by ARF, which can result from a single severe episode or from multiple recurrent episodes of the illness, is known as rheumatic heart disease.
