It was a disease caused by the Variola virus both type major and minor. It was spread through means of contact such as airborne,bloodborne, and foodborne . Since it was a virus it hacked cells of the body and and reproduced in host cells giving the body terrible effects and symptoms such as permanent red scars/spots , vomiting, fever and colds. It can be tested and confirmed through the use of an electron microscope and through physical findings. .
PREVENTION AND CONTROL OF HEPATITIS B IN THE UNITED STATES. Infected mothers with (HBsAG) Hepatitis B surface antigen, an indicator of high levels of virus is blood have transmitted infection to their new born babies. Also Injected drug use, needle sticks, tattooing have passed on disease to uninfected people (P.& J. Engelkirk p.316). Other types of health care associated transmission also known as nosocomial outbreaks involving patient-to-patient transmission have occurred in association with a variety of transmission vehicles including multi dose vials, re-usable finger stick devices and other contaminated medical equipment. (CDC,
There’s evidence that this virus existed all the way back to Egyptian times when a mummified child showed a disfigured and shortened lower limb. This virus that attacks the nerves of the brain and spinal cord and may result in paralysis of muscles, usually asymmetrically, with lower limb involvement. Polio is spread through person-to-person contact, typically fecal-oral transmission. When a child is infected with wild poliovirus, the virus enters the body through the mouth and multiplies in the intestine. It is then shed into the environment through the feces where it can spread rapidly through a community, especially in situations where poor hygiene and sanitation are lacking.
Primary infection occurs in epithelial cells leading to a skin rash and fever as a phenotype. When virions spread to adjacent sensory neurons, a lifelong infection is established (Owen, Crump, & Graham, 2015). Both primary and secondary diseases have a significant morbidity and mortality but thanks to advances in diagnostic and the production of vaccines, it is possible to decrease their burden (Gershon, 2013). 1.1 Varicella: Varicella (chickenpox), the primary infection of VZV, is characterized by cutaneous eruption typically seen in children. In adults, this primary infection is more severe and in immunocompromised patients, it can be followed by complications such as, high fever, pneumonia, encephalitis and hepatitis (Gershon et al., 2013).
The evolution of the disease develops in stages and other outbreak in which the effects of the disease forwarded. Also, there are very severe lupus and some not so serious as those that occur and are limited to skin conditions. In general, when a person is diagnosed with lupus, immune cells are attacking own body causing inflammation and tissue
A fomite is an inanimate object that can become infected with virus, and in this case, transmit it through skin contact. Fomites that are associated with the spread of the molluscum virus include clothing, towels, bath sponges, pool equipment, and toys. There is speculation that the virus can also be spread by sharing swimming pools, baths, saunas, and other warm, wet environments but researchers who study the etiology of the virus don’t believe this to be likely. Molluscum can be spread by autoinoculation, the process of scratching a lesion and touching your body, or another body, somewhere else. Shaving and electrolysis (the removal of hair via electric current) have been shown to spread the virus.
HOST PATHOGEN INTERACTIONS LEARNING OBJECTIVES • Interaction between host and the pathogen • Defense mechanisms of host as well as the pathogen • Components of host-pathogen interactions • Basis of host-pathogen interactions • Types of interactions • Significance of host-pathogen interactions INTRODUCTION Every organic being is related, in the most essential yet often hidden manner, to that of all other organic beings, with which it comes into competition for food or residence, or from which it has to escape, or on which it preys… Charles Darwin ECOLOGY is the branch of science dealing with the classification and richness of organisms in the ecosystem and their kind of interactions with the
A microorganism is capable of causing diseases, this also known as a pathogen, is what begins with a host. The reservoir host is any living thing that is capable of sustaining growth of a pathogen such as a human, animal and/or an insect. Allowing this microorganism to invade any of the bodies, it can cause an infection to the body
The parasite, T. cruzi, then enters the body. It then multiplies within the cells of the body until the cells burst and release the parasites into the blood stream. Other ways it can be spread: • Blood transfusion from an infected person. • Mother to baby
These enterovirus are present in many things such as mucus, feces and saliva and are transmitted through direct contact with someone or something that is infected. The virus then enters the mouth and travels to the brain so that it can multiply there. Encephalitis can also caused by the same infections, but more than half of the cases remain undiagnosed. Most cases of encephalitis are caused by enteroviruses, herpes simplex virus types 1 and 2, West Nile virus or rabies. Herpes simplex encephalitis can affect anyone at any age but is usually seen with people under the age of twenty or people over the age of forty.
