The infectious agent of chickenpox is the virus varicella-zoster. This virus lives in the nervous system for decades and causes shingles, a very painful rash that follows a nerve pathway. Chickenpox causes the infected person to break out into itchy blisters – usually 250-500 covering the body. In Chickenpox: Symptoms, causes, and prevention Christian Nordqvist lists the symptoms of chicken pox as malaise, fever, muscle aches, loss of appetite and nausea, and in severe cases, difficulty breathing. It can cause pneumonia in adults. When pregnant women contract chickenpox, their unborn child is at risk for shingles within the first two years of life. As well, some babies may develop congenital varicella syndrome, which may include:
• Scars
• Problems

Thus it is virulent, waiting for the host’s body to become weak enough to allow it to flourish.
Chickenpox is spread only between humans. There is no evidence of other carriers. One can catch chickenpox from surfaces that are contaminated with the exudate, linens and objects. As well, inadvertent contact with a person infected by the disease is easily spread to others via their respiratory system – coughing, sneezing and even just talking. Since the disease is airborne, it is quite easily transmitted to another by simply inhabiting the same room for over 15 minutes (Chickenpox, 2017).
The portals of exit for the virus are both direct and indirect. The host may infect another even before their own symptoms manifest; these may not become apparent for up to two weeks. The mechanism is as follows: after entry through the respiratory route, the virus replicates, inhabits the lymphatic system and finally the blood

Reasons for this are the lack of information about the virus and how it is spread, lack of resources to obtain the vaccine, inexperience with or inability to isolate infected patients, the extended incubation period, and the host’s inability to recognize their illness even when symptoms do appear.
Imagine being on an airplane where fresh air is mixed with cabin air. This contained space filled with coughing and sneezing passengers is a great place to pick up a cold. But imagine if one of the passengers was infected with an airborne disease like chickenpox. Those who have not already had the disease or been immunized against the virus would have a very high chance of being infected. Again, as the NHS (2017) reports, it takes only fifteen minutes of conversation for the virus to lodge in the well person’s system and begin to
[1, 4, 5, 9, 13] There have been no documented cases where a human has contracted the disease from another human. [4] It appears, based on field and lab data, that infection requires direct contact with the virus through means such as contact with infective bodily secretions, urine, or tissues. [12] It is unknown to scientists how the virus can be maintained in the bat populations and avoids extinction as the host species becomes immune to its presence. [14] The incubation period from time of infection to the onset of symptoms is about 5-14 days in experimentally induced animals [4] and 8-14 days in natural field cases.
Shingles, herpes zoster, is a very contagious and painful rash, or blister that appears on the skin. These rashes most commonly appear on the sides of the body in stripes. The stripes are made up of many very painful blisters caused by a certain type of virus. The varicella zoster, most commonly known as the chicken pox virus attacks the nerve roots in that area. The herpes zoster virus is in the herpes family, including HSV, herpes simple virus, which causes cold sores, fever blisters, and genital herpes. (WebMD, 2011) Most people are required to get the chicken pox shot when they are children although some do not. The chicken pox shot helps to keep out the virus by keeping it dormant in the nerves. The varicella zoster virus stays in a few cells; this is how shingles appear suddenly. It appears when the dormant cells become active in the later years of life.
This virus searches for a new vulnerable host in order to survive and carry the disease to the next victim. The critical aspect around the spread of a virus is how drastically the reproduction process occurs. Without being controlled, the contamination throughout any species causes the spread to take place in a toxic way, “On day one, there were two people. And then, four, and then, sixteen. In three months, it’s a billion.
It has not taken human to human transmission yet, that we know of. So far all cases of the virus result from people coming into close contact with bird blood or droppings. If the transmission of the virus does take human to human form, it could unleash a global pandemic. This is the first time in history that humans have been able to prepare themselves for an epidemic. The bird flu virus travels with migrating birds.
Disease and parasitism play a pervasive role in all life. Many of these diseases start with microparasites, which are characterized by their ability to reproduce directly within an individual host. They are also characterized by their small size, short duration of infection, and the production of an immune response in infected and recovered individuals. Microparasites which damage hosts in the course of their association are recognized as pathogens. The level of the interaction and the extent of the resultant damage depends on both the virulence of the pathogen, as well as the host defenses. If the pathogen can overcome the host defenses, the host will be damaged and may not survive. If on the other hand the host defenses overcome the pathogen, the microparasite may fail to establish itself within the host and die.
been previously touched by an infected person, will transmit the disease to the healthy person who
Influenza is very contagious and spreads rapidly from person to person. Influenza causes worldwide yearly epidemics. According to World Health organization Influenza affects 5-15% world’s population and resulting in 500,000 deaths yearly. Ottenberg stated that, in United States, an average of 200,000 were hospitalized and 36,000 died each year from influenza complications. Influenza is the sixth leading cause of death among US adults and is related to 1 in 20 death in persons older than 65 years. Disease control and prevention estimates indicate that infections like H1N1 which is one of the types of influenza, have resulted in an estimated 42 to 86 million cases and 8520 to 17620 deaths. As I mentioned earlier that infections like influenza are very contagious, they can spread easily from hcw to Patient and back to hcw. The most efficient and effective method of preventing influenza infection is vaccination(The best way to prevent influenza is with annual vaccination).(Sullivan,2010) (Gregory,Tosh &Jacobson, 2005). Motivated by a desire to actively avoid illness Influenza may increase the risk for death in people with existing heart, lung, or circulation disorders. In fact, the higher than average number of winter deaths in people with heart disease may be due only to the occurrence of influenza during those months.Vaccination provides immunity to fight against infection.To increase resistance to harm by modifying the environment to minimize preventable illness (NEED TO CHANGE WORDING)
In order to get shingles, an individual must first contract chicken pox. In my case, my parents deliberately exposed me to chicken pox when I was about four so I could just be done with it. The varicella zoster virus then lies dormant in nerve cells. Usually, reactivation of the virus is prevented by the body's immune system, especially T cells. However, when the immune system is compromised for some reason varicella zoster can recur as shingles...
Viruses can be transmitted in many ways. Being in contact with an infected person will most likely transfer the virus. One can also obtain the virus through swallowing, inhaling, and unsafe sex. Poor hygiene and eating habits usually increase the risk of catching a viral infection. Contracting a viral infection is followed by adverse s...
Chicken pox can be acquired any time during the year but is most prevalent in
The Ebola virus can easily be transmitted through direct contact of blood, organs, secretions of any kind and semen from any person infected. Another method is that of used needles that have been infected. With all countries considered, the 3rd world and the reuse of needles are a common practice, due to lack of funds and supplies. Though recovered patients pose no serious threat, the virus is present up to 7 weeks after being treated. Vomit and diarrhea contain the infected blood and mucus so any contact with this, e.g. in poor drinking water can cause contraction of the virus. Luckily enough Ebola is not airborne and in some cases due to its self-limiting nature, it has been known to die out within a person before killing the host. In one case when a Swiss researcher found the Ebola Tai virus, she contracted it from a chimpanzee. This was during an investigation into the spur of deaths among them at the time. To this day, there is still no evidence as to what host carried the virus before humans and no location of the virus is known.
For pregnant women 2 weeks is when the symptoms will come in to effect they will cause skin sores, rashes, fever, and anemia. For infected infants they will grow up having damaged teeth and brains and eyes. Blindness is one way of having this disease you will start to lose your eyesight. Paralysis is also another way is affected it, because you can suffer from the loss of the ability to move a body part like a leg as an example. The last part is you will have problems with your bones and internal organs; including your
The virus attacks the lymph nodes and lungs. The buboes formed from the virus are usually formed in the groin or armpit depending on the closest lymph node. The plague is highly contagious, spread by speaking, coughing, and sneezing. There are two types of plague, the septimic and the pneumonic.
Chicken pox from a virus called varicella-zoster, small maternal disease is an infectious disease spreading from one person to another.
