Chickenpox is highly contagious and can be transmitted through physical contact, coughing or sneezing, and contact with fluid from blisters. Vaccination can help prevent transmission, but in rare cases, it can cause a mild case of the disease. Shingles can also transmit the virus.
There are several ways that chickenpox, which is highly contagious, can be passed from one person to another. One of the most common methods of transmitting chickenpox is through physical contact with an actively contagious, infected person. The virus can also spread through the air when a sick person coughs or sneezes, as it is present in saliva. Sometimes children who receive the chickenpox vaccine can develop a mild case of the disease. In rare cases, people with shingles can cause a chickenpox infection in someone who comes into contact with them.
Chickenpox infection causes patients to develop fluid-filled blisters over much of their skin. Contact with this fluid is a common cause of transmission of chickenpox. This can happen if a person touches actual blisters when they break, or it can happen if they handle things like bed sheets or towels that the infected person has used. Caregivers of those who are infected should be careful when touching the patient or her belongings to avoid infection.
Saliva or the mucous membranes of the respiratory tract can also be the source of chickenpox transmission. If a patient coughs or sneezes while actively contagious, the virus can travel through the air and be breathed in by another person, spreading the infection. Sick people who don’t wash their hands properly can also leave the virus on surfaces where it can be picked up by others. This is especially problematic in places like schools where children, who are typically the ones to get chickenpox, are often in close proximity to each other.
One method that can help stop the transmission of chickenpox is vaccination against the varicella-zoster virus that causes it; in some cases, however, the vaccine can cause a mild chickenpox infection. Children in these cases typically show much less severe and less severe symptoms than full-blown cases of the disease and usually recover much faster. However, they are still contagious and thus must be careful about spreading them further.
After being infected with chickenpox, the varicella-zoster virus usually stays in the body and can become active later in life as shingles. This condition causes a painful rash that can potentially transmit the virus. Although rare, a person who comes into physical contact with this rash can develop a case of chicken pox.
