Black Pox is a symptom of smallpox that is caused by bleeding under the skin which makes it look charred or black. this symptom usually indicates that a person with smallpox is going to die. smallpox was an infectious disease caused by one of two virus variants: Variola major or minor. Variola major was the more severe and more common form, it included higher fevers and extensive rashes. Variola minor was the less common form and far more less severe with death rates of only 1 percent. The Variola virus evolved from a rodent virus between 16,000 to 68,000 years ago.…
The Nipah Virus causes severe illness. A person with this infection will get a respiratory disease, a term that includes extreme conditions affecting the organs and tissues that make gaseous exchange possible in organisms, and includes conditions of the upper respiratory tract, trachea, bronchi, alveoli, pleura and the nerves and muscles of breathing. (Source c)…
Shingles occurs when the virus that causes chickenpox starts up again in your body. After you get better from chickenpox, the virus "sleeps" (is dormant) in your nerve roots. In some people, it stays dormant forever. In others, the virus "wakes up" when disease, stress, or aging weakens the immune system. But after the virus becomes active again, it can only cause shingles, not chickenpox.…
A virus is a small infectious agent that replicates only inside the living cells of other organisms. A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell to produce many more viruses. Viruses can infect all types of life forms, such as animals and plants to microorganisms, including bacteria and archaea.…
A virus may not kill a host cell but may become inactive for a period…
These patches can be easily spotted since they are a bright red and have small blisters (more like pimples) that contain the virus in a fluid form. The patches can radiate in itchiness, pain, or a burning sensation that stays constant for long periods of time. Shingles is caused by the Varicella-Zoster virus which is the same virus that creates Chickenpox in young children. Shingles can only happen if a person has had Chickenpox in the past, in which the Varicella-Zoster virus stays dormant in the nerve roots and reawakens later in life, in many cases the virus stays dormant forever. A person is most at risk of getting Shingles if they are over the age of 50 and as of today approximately 1 in 3 people in America will get Shingles. Although 100 Shingles related deaths happen every year, it is usually in rare cases involving people with extremely poor immune systems. While on the topic about poor immune systems, I want to move on to the next point which is the transmission of…
(Talaro) The Varicella-zoster virus is a DNA virus in the same group as the herpes virus. (Varicella) Latency is the main virulence property of Varicella. Human are the sole reservoir of the chickenpox and is spread through human-to-human contact. Chickenpox can be spread through the respiratory tract and conjunctiva. Respiratory transmission occurs through person-to-person when respiratory tract secretions are transferred from an infected individual to a healthy individual. Another form of transmission of Varicella is through respiratory contact of airborne droplets or inhaling aerosols.…
Shingles, also known as herpes zoster, is a reactivation of the chickenpox virus, causing a painful rash. Shingles can occur anywhere on your body. They most often appear on your torso. They look like a small strip of blisters. Shingles is caused by the same virus that causes chickenpox. After you've had chickenpox, the virus is already in your spinal cord and brain, but inactive. The virus may reactivate as shingles years later. Shingles can be very painful. Vaccines can help lower the risk of shingles, and early treatment can help shorten a shingles infection. Shingles can cause death, but is rare.…
Herpes Zoster is caused by varicella zoster virus, which is the same virus that causes chicken pox. When a person gets chicken pox and recovers from it, the virus does not go away, it remains in the body, but becomes dormant (inactive). Later in life, the virus can reactivate itself causing herpes zoster. Herpes zoster itself cannot be spread from person to person, but the varicella zoster virus can be spread from one person with active shingles to another person who has never had chicken pox. That…
resembles the herpes virus. The virus can be released into the air by coughing or sneezing, spreading the virus from person to person. The virus also can be spread by touching the fluids from a chickenpox blister. Chickenpox is so contagious that an individual who has never had exposure to chickenpox has an 80% chance of obtaining the disease when in close contact with an infected individual. According to Pub Med Health (2009) “Most children with chickenpox act sick, with symptoms such as a fever, headache, tummy ache, or loss of appetite…
Shingles is a viral infection as a result of which you end up with a painful rash. It is caused by a virus called varicella zoster. This is the same virus which leads to chickenpox. If you have already had chickenpox, this shingles virus remains dormant in your body. However, it could become active again causing the rash. It can be found on any body part. Generally small sections of the body are affected by it.…
Shingles, also known as herpes zoster, is a disease caused by the reactivation of the varicela zoster virus – the very same virus that produces chicken pox. This virus resides in dormant state in the nerves and exploits a weakened immune system and/or extreme emotional/physical stress…
It is easily passed between members of families and school classmates through airborne particles, droplets in the air, and fluid from the blisters or sores. It also can be transmitted indirectly by contact with articles of clothing and other items exposed to open sores. Patients are contagious up to five days, when all of the sores have crusted over, the person is usually no longer contagious.…
Varicella zoster is a highly infectious viral disease, known familiarly as chickenpox, which is a member of the herpes group of viruses. Varicella zoster is a DNA virus and is a member of the herpes virus group. Like other herpes viruses, VZV has the capacity to persist in the body after the primary (first) infection as a latent infection.It is usually a mild disease that lasts a short time in healthy children. However, it can be severe in adults and may cause serious or even fatal complications in people of any age. Chickenpox is a vaccine preventable disease, and vaccination is recommended as part of routine childhood immunisation. The vaccine should not be given to children with severe immune deficiency diseases, including HIV/AIDS, or to…
The Mydoom virus (also known as a worm and as Win32.Mydoom.A) was a very damaging computer virus that affected Microsoft Windows-based computers. The worm was spread through mass emailing, disguised as badly sent email.…
