Zika is a virus that a person can catch if bitten by an infected mosquito. First seen in Africa about 70 years ago, the virus recently has spread throughout the world, particularly in tropical areas where certain types of mosquitoes live. The main problem with Zika is its effect on unborn babies. In pregnant women, the virus can cause miscarriage, stillborn babies, or babies with birth defects. One serious birth defect caused by Zika is microcephaly.
According to the CDC, “approximately half of the babies less than one year old who get pertussis need treatment in the hospital” (Fast Facts). The pertussis vaccine, discovered in 1906 was developed by Bordet and Gengou. It is a common virus that is more well known for affecting babies. The virus also known as “Whooping Cough” for the sound the host makes while trying to catch their breath. A single person with, “pertussis can infect up to 12 to 15 other people” (Pertussis F.A.Q).
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,
A disease vector is any agent that transmits and carries an infectious pathogen into another living organism. These vectors have immunity to the pathogen and thus allows for the successful transport of the pathogen. Not every vector is able to carry every pathogen and ecological restrains also limit the spread of the disease due to the inability of the vector to survive in different kinds of environments. Arthropods can serve as vectors and play an important role in disease transmission. These vectors include mosquitoes, fleas, sand flies, lice, ticks, and mites.
How to Treat Bedbugs Anyone can end up being "attacked" by bed bugs. Contrary to popular belief, even a very clean house can suffer from these insects, as the infestation can be brought by clothing, in suitcases and luggage, as well as many other surfaces. The severity of symptoms associated with bed bug bites varies by individual. Some do not even notice they have been stung, while others may be allergic, developing redness, blemishes and a lot of itching. Before attempting to use any type of medicine to treat this type of sting, check that it was really a bed bug.
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. .
How many people do you think have thought about dying from such a little creature? Yellow fever is a deadly flu-like disease caused by mosquitoes. The disease can give you a high fever and turn your eyes and skin yellow, which is also known as jaundice. There are different stages of yellow fever. There is no cure for yellow fever, but it can be prevented with a vaccine (Healthline).
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).
Malaria is a contagious disease caused by five different Plasmodium parasites that have similar life cycles.1 These parasites have a complex life cycle that requires an insect vector most commonly female Anopheles mosquito and a human host. The life cycle of the malaria parasite is composed of human stages and mosquito stages.2 The discovery of the first stage during which the parasites develop in the liver before entering the blood stream was done by Henry Shortt and Cyril Garnham in 1948. In 1982, another discovery was made by Wojciech Krotoski demonstrating the presence of dormant period in the liver that occurs in the final stage. These discoveries play an important role in the understanding of the life cycle of malaria prasites.1 Moreover,
The story of Ewald begins with his concerns on why some diseases are contagious while others ignore, leading to his visitation at the school of hygiene. He needed to understand the relationship existing between an host and parasites cause in his mind there shouldn’t be any kind of connection. His argument was based on the drastical effect it causes due to the fact that it immobilizes its patient, and if not taking care of will leads to a rapid spread making the surrounding contagious comparing viruses that have a human host not been succeeding in transmitting diseases from host to another host than insect like mosquitoes which transport the virus malaria through biting since it immobilized the human contract, leading to a drastic break down and his reason has to do with the rapid transmission and effects of malaria, and yellow fever was still transported actively by this insect through bites than cold. This led to his understanding of the massive deadly that had occurred in the previous year because the bacteria cause diarrhea isn’t culpable enough as mosquitoes in being productive with the transmission process.
