A host species that transmits an infectious disease to another host species is called a ________ of the disease, and a disease that is transmitted in this way is called a __________
Answer: Vector, communicable disease.
( In the case of communicable disease, the host species that transmit an infectious disease to another host species is called vector of the disease. These vectors are disease carrying agent.)
A host species that transmits an infectious disease to another host species is called a ________...
There are many ways that an environmental infectious disease can be transmitted to a host. Describe the differences between vectorborne diseases and zoonotic diseases. What type of infectious disease is associated with each of these categories?
What is the “host” in infectious disease epidemiology?
Briefly describe an infectious disease and how it affects a human host.
Imagine you work in the infectious disease department of the Centers for Disease Control and Prevention. Recently, an unknown emerging disease has begun to spread in the United States that seems to show symptoms similar to influenza and measles. Not all people infected show all the symptoms, and current vaccinations do not prevent a person from catching the unknown disease. Apply the knowledge you know now about infectious agents and means of transmission. For this assignment: Provide a brief overview...

Who was the worlds first infectious disease physician? I understand whoever it was wrote some poetry and did their study on a sexually transmitted disease. It is NOT Hippocrates! Any info is appreciated.
Infectious diseases can emerge through genetic, social and behavioural changes in the host and/or pathogen. Provide: (a) two examples of genetic changes, and (b) two examples of social or behavioural changes that have enabled new infectious diseases or new strains to emerge. In all four examples that you give, name the pathogens and explain how the changes led to disease emergence. Mandatory word limit: Write no more than 200 words in total.
3. Using the term incidence, contrast a seasonal endemic infectious disease with an epidemic infectious disease over the course of one year. 4a. Using SARS-CoV as a specific example, describe how epidemiologists can track infections during an epidemic by a) measuring antibody levels (seroconversion) and b) using PCR methods. 4b. During the course of a single infection, which method will detect SARS-CoV earliest? Explain why. 5. An epidemiologist trying to identify the agent causing a novel flesh-eating epidemic infectious disease...
Fill in the blank: Malaria is caused by several species of the protozoan parasite ____________________, which has a complicated life cycle. True or False: Animal parasites are organisms that have become adapted to living within or on the body of another animal, called the ____________________. True or False: Type 2 herpes usually infects the oral mucous membrane, where it causes the familiar fever blisters. True or False: A pregnant woman with a genital herpes infection may or may not infect...
1.A research group is investigating the potential infectious nature of a disease. From ulcerative skin lesions in mice they were able to grow as pure cultures a Gram negative microorganism. They inoculated this microorganism into the skin of healthy mice and reproduced the same ulcerative skin lesions. According to the Koch’s postulated these experimental evidences are sufficient to confirm that the Gram negative microorganism is the causative agent of the studied disease. (T/F) 2. Exotoxins can cause tissue damage during...
