Student of class 9 had to present a seminar on 'dengue fever'. They wanted to introduce the disease by starting with: 1)immediate cause of the disease. 2)Definition of Infectious disease. 3)Pathogen causing Dengue fever. 4)Vector Responsible Foe dengue Microbe. Can you help me to Explain the above Points? GIVE DETAILS..
Answers
Answer:
Explanation:1)-immediate cause of the disease
Depends on the disease, obviously (or it should be obvious). Each has its own cause, cure, and prevention. There is no possible way to cure or treat all diseases.
Infectious diseases are caused by infectious agents: bacteria, viruses, fungi, protozoans, helminths, parasites, etc. (Ex: the cold, athlete’s foot, AIDS, malaria, head lice). You prevent these by not being infected or by getting vaccinated against them. Cures and treatments vary.
2)-defination of infectious disease
A disease that is caused by a microorganism, such as a bacterium, virus, or protozoan, that is not normally found in the body and is capable of causing infection. Some, but not all, infectious diseases are contagious, meaning they can spread from person to person.
3)Pathogen causing Dengue fever.
Dengue fever, also known as breakbone fever, is a mosquito-borne infection that can lead to a severe flu-like illness. It is caused by four different viruses and spread by Aedes mosquitoes.
4)-Vector Responsible Foe dengue
Vector of dengue fever. Dengue infection is transmitted from one person to other by the bite of an infected female Aedes mosquito. Dengue fever (DF) is a viral infection caused by any of the four types of dengue virus ( DENV -1 to DENV-4).

Answer:
Explana(i) Immediate cause is the main cause of disease through which virus disease has accumulated in the body. Dengue is the immediate cause of Dengue fever.
(ii) Infectious diseases are those diseases in which microbes are immediate cause and spread from one person to another through various means like air, water etc., e.g., chickenpox, cholera, etc.
(iii) Pathogens causing dengue fever are microbes causing dengue fever, i.e., dengue virus.
(iv) Vector responsible for dengue microbe is the female mosquito known as Anopheles. Female mosquitoes require blood as a meal as it is necessary for meeting their high protein requirement for laying eggs. When female mosquito stings a person for taking blood during this act, virus is introduced into the blood of a healthy person
