An infection is an invasion and multiplying of pathogenic microbes in the body tissues in which they are not usually present (1). Ask a Doctor Online Now!A colonization is the usual presence of non-pathogenic and even potentially pathogenic microbes on the skin, in the nose, mouth, bowel, penile or vaginal mucosa, as a part of normal human flora, in the amount not harmful for the body – this is not an infection. A contamination is the presence of germs which do not multiply, for example, in a contaminated (not infected)wound. A carrier state is the non-usual presence of pathogenic microbes in the body, in the way not harmful for the carrier, but potentially dangerous for others, since the carrier is usually contagious. An overgrowth of microbes, non-pathogenic in small amount, but pathogenic in large amount, for example, an overgrowth of Clostridium difficile bacteria in the colon can cause life threatening pseudomembranous colitis. Re-activation of an infection may occur; for example, a Varicella zoster virus, which has remained dormant in the roots of the spinal nerves after successfully healed chicken pox, may be re-activated during stress or certain disease, and can cause shingles.
Bacteremia, viremia, fungemia and parasitemia (the presence of microbes in the blood) may result in an infection of other organs, or sepsis. Systemic infection, like influenza, affects the whole body and causes systemic symptoms, like general malaise, muscle pains, fever, nausea, etc. Localized infection, like cellulitis, is limited to one or few body parts and presents with localized symptoms, like redness, swelling, pain or localized (nasal, ear, etc.) discharge.
Chronic infection, like tuberculosis or AIDS, may last from several weeks to several years. Recurrent infection is one that frequently affects a person, like folliculitis in those who share the same sport equipment, or fungal infections  in those with lowered immunity.
Invasion of multi-cellular parasites, like intestinal worms or head lice, into the body is called infestation.
Viral infections are often systemic and may cause fever, headache, runny nose, sore throat, muscle and joint pains, diarrhea, skin rash, etc.
Fungal (yeast) infections in a person with a healthy immune system usually affect only the skin. In a person with a weak immune system, fungal infections, commonly caused by a yeast Candida albicans, may appear in the mouth (oral thrush), esophagus, rectum or vagina; systemic candidiasis is severe and commonly fatal infection. Parasitic infections cause different symptoms, depending on the type of parasite and organ affected. Infestation (Latin infestare = to attack, disturb) is an invasion of multi-cellular parasites, like intestinal worms (helminths) or head lice to the body. In medical terms, the incubation period is the time from when a person is exposed to an infectious agent (pathogenic microorganism) till the onset of signs and symptoms. Fever in localized skin infections or food poisoning may be absent, in tuberculosis or viral pneumonia it is usually low-grade, in influenza moderate, and in bacterial pneumonia or sepsis high.
Pain in childhood viral infections and flu is usually general and vague, and in localized bacterial infections, like bacterial prostatitis, localized and intense. Discharge from the nose, eyes, ears, trachea, bronchi and lungs (phlegm, sputum), nipples, bowel (mucus in the stool), urethra, vagina and wounds may appear in all types of infections. An incubation period is the time elapsed between exposure to pathogenic microbes and symptoms appearance.
An autoinfection – the spread of an infection from one body part to another, usually by hands or clothes (folliculitis, impetigo).
By drinking contaminated water, one can contract stomach flu, cholera, dysentery, typhoid fever, amebiasis, etc. By swimming in contaminated swimming or spa pools, or lakes, one can contract hot tub folliculitis, intestinal parasite Cryptosporidium, eye and middle ear infections. Industrial cooling or hot water systems, air condition and room-air humidifiers can be a source of Legionella.
During walking barefoot, Clostridium tetani, sandworms, or intestinal parasites, like Strongyloides stercoralis or hookworms can be contacted. Infections acquired in hospitals can be dangerous, since causing microbes are often resistant to regular antibiotics, and patients infected are often already seriously ill. Legionella may be sometimes found in the tap water in newly opened or poorly maintained hospitals.
A fomite is an inanimate object or substance capable of transmitting infectious agents (microorganisms) from one object to another.
Ask a Doctor Online Now!Microbes may make harm by releasing toxins, for example, in food poisoning, a parasite Entameba hystolytica can release toxins, which can destroy colonic mucosa, resulting in bleeding ulcers and diarrhea. Invasion of microbes triggers immune response of the body and attracts inflammatory cells, like leukocytes, and substances, like cytokines, which attack the microbes.


Effective anti-microbial medications for most infections, except viral ones, are available.

Amir, the base of infection is an invasion of microorganism into your body what results in inflammation.
Pink eye (commonly known as red eye in Singapore), medically termed as conjunctivitis, refers to an inflammation of the conjunctiva - the mucous membrane that covers the whites (sclera) of the eye and the underside of the eyelids. This tissue is vulnerable to infection by bacteria and viruses just as our ears and throats may be infected.When infected, the blood vessels in the conjunctiva becomes inflamed also.
That is why your eyes appear reddish or pink because the blood vessels become more visible.Conjunctivitis is a very common type of eye infection. This includes those related to sexually transmitted diseases (STDs).This type of pink eye often develops quickly and can be recognized by yellow to green discharge that contains pus and sticky. Children And Bacterial ConjunctivitisThis type of pink eye is especially common in children probably due to the less than adequate hand-washing and other hygienic practices. Bacterial conjunctivitis is usually not serious and will go away within 10 days even without treatment.If you are diagnosed with bacterial conjunctivitis, your doctor will typically give you topical antibiotic eye drops or eye ointments.
These eye drops can be useful as it can reduce the time it takes to full recovery.Hot compress (very warm water on washcloth) will be helpful also specifically if your eyelids are sticking together in the morning. These diseases are both bacterial in nature and can infect the newborna€™s eye if the treatment of the mother isn't complete prior to giving birth.In such cases, antibiotic ointment is administered to the infantsa€™ eyes just after birth to negate any bacteria that may have passed to the newborn. Viral ConjunctivitisViral conjunctivitis is the leading cause of conjunctivitis among adults and is associated with upper respiratory infections such as flu, measles or the common cold. Viral conjunctivitis looks a little different from the bacterial type as the discharge from eyes is usually more watery and less sticky.The infected eye also looks more pink than red and your vision is usually normal or close to normal. Papillary conjunctivitis is more commonly caused by the constant presence of a soft contact lens.
Diabetes is a chronic ailment that develops when the pancreas becomes unable to create sufficient insulin in the body or the healthy cells turn resistant to insulin and leads to abnormally increased levels of sugar in the blood.
Some of the health problems that can be caused due to diabetes include blood pressure, heart diseases, eye nerve damage, and skin diseases. Many times, eczema is considered to be one of the diseases that are causes due to diabetes. Diabetes causes the natural body fat to break down on its own when the body begins to lose its energy.
You must not ignore it and seek medical assistance because many times, when this condition is ignored, it can lead to severe complications such as yeast infection causing eczema like skin rashes and itchy scaly patches or even gangrene. Infection is the invasion of disease-causing organisms in host organism’s body, where disease-causing organisms multiplies, reacts and produces toxins in host organism’s bodily tissues.

For example, if you have Staphylococcus aureus bacteria (a common cause of skin infections) in your nose, you may infect others, even if you alone never develop an infection. Small intestinal bacterial overgrowth due to invasion of otherwise non-harmful colonic bacteria into the small intestine can cause bloating and diarrhea. Example: infection with Epstein-Barr virus (EBV), which can cause infectious mononucleosis, often triggers no symptoms in small children.
Examples of bacterial infections: staphylococcal skin infections, pseudomonas folliculitis, streptococcal pharyngitis, osteomyelitis, pneumococcal pneumonia, bacterial meningitis, etc. Patchy areas with a brownish or reddish scaly rash on the scalp (scalp ringworm), trunk, limbs or groin (jock itch), peeled skin on the hands or feet (athlete’s foot), or discolored or cracked nails are typical symptoms of a skin fungal infection. Intestinal parasites cause bloating, diarrhea, mucus in the stool and eventual weight loss.
Not every person who comes into contact with an infectious agent will become infected but once the infection is acquired, the micoorganism will take a period of time during which it multiplies and spreads within the body until the point that signs and symptoms become evident. There is no single specific symptom but a combination of symptoms and signs that speak for an infection. In everyday speech, only infections transmitted directly from person to person (like flu) are considered as contagious. Once contaminated, fomites may carry microbes for few minutes or several weeks, depending on the type of the microbe and certain circumstances, like air humidity and temperature.
Such a defense reaction regularly results in an inflammation of infected tissue, which can be observed, for example, as purulent discharge in common cold or swollen joint in bacterial arthritis.


For example, Streptococcus pneumoniae , causing pneumonia, can trigger fluid collection in the lungs, impeding oxygen exchange between the air and the blood and thus reducing the oxygen supply to the tissues, what may result in death.
When in doubt, a doctor can take a sample of blood, urine, stool, sputum, nasal or other discharge and send it to laboratory, where microbes can be determined by serologic tests or a culture. A doctor can often make a diagnosis from symptoms and physical examination, but in doubtfull or severe cases, lab tests has to be done to determine the causing microbe. They just like to touch their eyes so much.Infants can also be affected by this form of conjunctivitis due to an incompletely opened tear duct. And yes, you will feel pain.In this case, antibiotics will not be effective but applying a warm washcloth to the eyes several times a day can relieve symptoms. This conjunctivitis causes itchiness, heavy discharge, excessive tearing and red bumps (called papillae) forming underside of the eyelid. Many times, some of the skin diseases are mistaken as eczema, which is originally caused due to some skin irritants and not due to insulin abnormalities or disrupted levels of blood sugar.
When the glucose level increases in the blood stream, kidneys intend to flush out the extra sugar content from the body. When you observe that you are frequently going to the toilet more than usual, then you must check with your physician to find out if you are suffering from diabetes or not. You may realize this only when you carefully notice that even small wounds are taking a very long time to heal. The kidney attempts to flush out the extra glucose content from the blood stream in the form of urine. Diabetes can cause severe eye problems such as blurry vision, strain, eye pain and headaches.
Contamination also refers to presence of pathogenic microbes on medical equipment, in the water, food etc.
Examples of viral infections: influenza, childhood diseases like chicken pox, rubella, rubeolla and infectious mononucleosis, AIDS, viral hepatitis, viral hemorrhagic fever, etc.
Effective over the counter or prescribed anti-fungal ointments and oral medications are available. In diabetes, where excessive thirst and hunger are the main symptoms, eczema does not show any of these symptoms. But, when this condition is left untreated for a long time, it can cause severe complications affecting the entire body. Suddenly, you may observe that your appetite has increased manifolds and you wish to eat a lot. The inflammation of skin due to bacterial skin infection is called as infective dermatitis. It may also clear up quickly as a result of the treatments already being used for systemic viral condition.
But, diabetes causes skin infections and bacterial manifestations that can look similar to eczema. The skin may become dry and thick with certain areas showing hair loss and color disruptions.
Except of acyclovir and related antiviral drugs, at present, there is not a lot of effective medicines for viral diseases available.
Surgical removal of parasitic cysts, like in Echinococcus, from the liver, bones, brain or lungs is sometimes required.
The infection or the inflammation of the skin occurs in the deep epidermis (outermost layer of the skin) with lymphatic spread.Signs and symptoms – Fever with chills, fatigue, vomiting, headaches and generalized weakness within 48 hours of infection.
Severe infections can lead to vesicles and petechiae with skin necrosis (premature death of cells of human tissue). On the other hand, ‘bullous impetigo’ is mainly seen in children younger than 2 years with complaints of fluid-filled, painless blisters mostly on the legs, arms and trunk with itchy skin.In ecthyma, lesions are painful with fluid or pus-filled with redness and soreness, usually seen on legs and arms can lead to deep ulcers in the skin. Staphylococcus aureus and Streptococcus pyogenes are the types of bacteria responsible for this bacterial skin infection, which invades through cuts, blisters, lacerated or surgical wounds, break of skin or insect bites.
