People who have never had chicken pox or have not been vaccinated must steer clear from fresh, active blisters. It cannot however, be transmitted through casual, indirect contact. Once the blisters develop a crust, the virus can no longer be spread.

Shingles cannot be passed from one person to another. However, the virus that causes shingles, VZV, can be spread from a person with active shingles to a person who has never had chickenpox through direct contact with the rash. The person exposed would develop chickenpox, not shingles. The virus is not spread through sneezing, coughing or casual contact. A person with shingles can spread the disease when the rash is in the blister-phase. See similar questions...

The risk of spreading shingles is low if the rash is covered. People with shingles should keep the rash covered, not touch or scratch the rash, and wash their hands often to prevent the spread of VZV. Once the rash has developed crusts, the person is no longer contagious. See similar questions...

In the United States, asphalt shingles are categorized as either organic-based or fiberglass-based. Organic-based asphalt shingles are manufactured with a base (also termed mat or substrate) made of various cellulose fibers, such as recycled waste paper and wood fibers. This organic base is then saturated with a specially formulated asphalt coating and surfaced with weather resistant mineral granules. See similar questions...

Shingles -- also called varicella-zoster -- is a painful skin disease caused by a reactivation of the chickenpox virus. It is distinctive because it affects only one side of the body. The early signs of shingles usually develop in three stages: severe pain or tingling, possibly itchy rash, and blisters that look like chickenpox. See similar questions...

VRE is usually passed to others by direct contact with stool, urine or blood containing VRE. It can also be spread indirectly via the hands of healthcare providers or on contaminated environmental surfaces. VRE usually is not spread through casual contact such as touching or hugging. VRE is not spread through the air by coughing or sneezing. See similar questions...

There is still much debate in the scientific community regarding how BSE is spread. At the present time, BSE is thought to be spread in tissue from the central nervous system (brain, spinal cord) as well as distal ileum, some of which can be present in meat and bone meal. BSE is not spread by animal-to-animal contact. In other words, an animal infected with BSE cannot infect another animal with which it is penned or pastured. See similar questions...

Wild waterfowl are the natural reservoir of all influenza A viruses. They have probably carried influenza viruses, including H5 and H7 subtypes in the low pathogenic form with no apparent harm for centuries. Evidence now suggests that migratory birds can introduce low pathogenic H5 and H7 viruses into poultry flocks and these then mutate to the highly pathogenic form. See similar questions...

The primary way that SARS appears to spread is by close person-to-person contact. SARS-CoV is thought to be transmitted most readily by respiratory droplets (droplet spread) produced when an infected person coughs or sneezes. Droplet spread can happen when droplets from the cough or sneeze of an infected person are propelled a short distance (generally up to 3 feet) through the air and deposited on the mucous membranes of the mouth, nose, or eyes of persons who are nearby.

Fire ants reproduce opportunistically when conditions are wet and warm. They are found in all types of soil, but they do better in open pastures and sunny, grassy places than in thick shaded woods. Grassy medians of freeway and mowed pipeline and powerline rights of ways provide prime "freeways" for the ants too. Polygyne colonies (those with multiple queens/mound) can reproduce by budding off new colonies and spread by walking a few meters per year. See similar questions...

TB is spread through the air from one person to another. The bacteria get into the air when a person with TB disease of the lungs or throat coughs, shouts, sings, or sneezes. People nearby may breathe in the bacteria and become infected. You may have been exposed to TB if you spent a lot of time near someone with TB disease of the lungs or throat. Most people get TB from a family member, spouse, friend, or close coworker. See similar questions...

The virus is easily passed from person to person by breathing in air containing virus produced when an infected person talks, coughs or sneezes. It can spread through hand/face contact after touching a person or surface contaminated with the virus. See similar questions...

No, absolutely not. There has been significant testing on this issue and it has been proven that a Radiant Barrier installed in a residential attic will have not have any detrimental effect on the shingles. See similar questions...
