How Pathogens Make Us Sick Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease occurs when the cells in your body are damaged as a result of infection and signs and symptoms of an illness appear. The incidence of disease among those infected varies greatly depending on the particular pathogen and individual susceptibility. Many of the symptoms that make a person suffer during an infection fever, malaise, headache, rash result from the activities of the immune system trying to eliminate the infection from the body. In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader. Indeed, many of the symptoms that make a person suffer during an infection fever, malaise, headache, rash result from the activities of the immune system trying to eliminate the infection from the body. Pathogenic microbes challenge the immune system in many ways. Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), with the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system’s antibodies and other cells to target the invader. Many bacteria make us sick in the same way that viruses do, but they also have other strategies at their disposal. Sometimes bacteria multiply so rapidly they crowd out host tissues and disrupt normal function. Sometimes they kill cells and tissues outright. Sometimes they make toxins that can paralyze, destroy cells’ metabolic machinery, or precipitate a massive immune reaction that is itself toxic.

How to Reduce Eczema Itching Eczema, or atopic dermatitis, affects every age group, but most often arises in infancy or young childhood years. It consists of dry skin and a red itchy rash that can be found anywhere on the body, but is most commonly located on the bends of the arms and the backs of the knees.[1] It is commonly associated with other allergic-type conditions, meaning that people with food allergies, asthma, or hay fever are more likely to have eczema as well.[2] It also has a tendency to run in families. One of the most challenging symptoms to manage can be the itch, so read on to find out strategies to manage and reduce itching and scratching! 1 Choose fragrance-free products for sensitive skin. This includes products such as soap and laundry detergent, as well as things such as lotion.[4] Avoid bubble baths for children. Use non-drying, mild soaps such as Cetaphil, Dove, or Aveeno. Avoid any products that contain alcohol, as these can dry out skin. Avoid using things like fabric softeners or dryer sheets, as these usually have fragrances that can cause irritation. 2 Wear clothes with natural fibers close to your skin.[5] Fabrics such as cotton, silk, and bamboo are often less irritating on the skin than polyester.[6] Wool should be avoided, as it is known to irritate the skin. Wash new clothes before you wear them. This can help remove any agents left over from manufacturing that might irritate your skin

The length of time you're infectious for after having a viral infection depends on the type of virus involved. The infectious period often begins before you start to feel unwell or notice a rash. The infectious periods for some common viral infections are described below. Bronchitis The length of time that bronchitis is infectious varies, depending on its cause. In most cases, bronchitis is caused by the same viruses that cause the common cold or flu and you're likely to be infectious as long as you have cold or flu symptoms. Chickenpox Chickenpox is infectious from about one to two days before the rash appears until all the blisters have fully crusted or scabbed over. This is usually five to six days after the start of the rash. Common cold The common cold is infectious from a few days before your symptoms appear until all of the symptoms are gone. Most people will be infectious for around two weeks. Symptoms are usually worse during the first two to three days and this is when you're most likely to spread the virus. Flu (influenza) Flu is usually most infectious from the day your symptoms start and for a further three to seven days. Children and people with lowered immune systems may be infectious for a few days longer.
