Dengue Virus Infection: The Common Health Problems Essay.
Dengue is a viral disease that at present affects a enormous number of people in over 125 countries and is conscientious for a sizable number of deaths. There is no antiviral chemotherapy or vaccine for dengue virus and management of the disease is done on supportive measures, so various treatments are being investigated.
Generally, dengue is classified as a blood infection and the main reaction of the human body to dengue virus can be seen in the circulation. Due to its nature as a viral infection, lymphotropic phenomenon can be seen; the stimulation of lymphocytes results in lymphocytosis with atypical lymphocyte reactions.
In these cases, the infection first guides the immune system to identify the attendance of the Arboviruses. When the immune cells the virus infections later, the immune system reacts. These types of disease called dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) (22), engage more strict symptoms.
Dengue fever Dengue fever is a disease that is triggered by a virus (DENV) and there are different serotypes related viruses (DENV-1, DENV-.
Dengue: it’s Biology, Mode of Infection, Prevention and Control! Dengue or “break- bone disease” is an acute viral infection, caused by at least four serotypes (1, 2, 3 and 4) dengue viruses. Dengue virus is arbovirus capable of infecting human and causing disease.
The Dengue Virus, although virtually unknown in the United States, is prevalent in Latin America and Asia. It is also known as the breakbone fever. Transmitted by mosquitoes, the Dengue Virus causes rashes, headaches, and muscle pain. The hemorrhagic form of the virus may often cause death in the patient.
Dengue fever is a viral infection that is spread by the tiger mosquito (Aedes Aegypti). It has black and yellow strips and usually bites in the early morning or at dawn. The virus enters and breeds in white blood cells. Symptoms typically start appearing five to eight days after being ill. The virus has five diverse styles of increasing severity.
Dengue Viral Infection And Risk Of An Epidemic Biology Essay 0 Comments Dengue is an arbovirus disease caused by four dandy fever virus serotypes ( DEN-1, DEN-2, DEN-3 and DEN-4 ) and transmitted to worlds by mosquito as a vector.
The virus that causes dengue fever is a single-stranded RNA virus, which is encoded by an 11-kilobase genome encased within an icosahedral nucleocapsid (Shepherd, 2012, Etiology). This capsid is in turn encapsulated by a lipid envelope. There are currently four main serotypes of dengue: DENV-1, DENV-2, DENV-3, and DENV-4.
Dengue fever is an acute febrile disease caused by infection one of the serotypes of dengue virus which is transmitted by genus Aedes. It refers to a benign form of disease with systematic symptoms, fever and often rash associated with pain behind the eyes, the joints, and the bones.
Dengue infection involves a combination of factors related to host ( human ), virus ( dengue virus ), vector ( mosquito ), and the environment. The Aedes aegypti mosquito is the chief sender of dandy fever virus. Furthermore, the environment is a cardinal factor for dengue infection spread, particularly in tropical and sub-tropical states.
Dengue virus has increased dramatically within the last 20 years, becoming one of the worst mosquito-borne human pathogens with which tropical countries have to deal. Current estimates indicate that as many as 390 million infections occur each year, and many dengue infections are increasingly understood to be asymptomatic or subclinical.
However, in some cases a person may have already had dengue fever at one time, recovered, and then is reinfected with the virus. In these cases, the first infection teaches the immune system to recognize the presence of the arbovirus. When the immune cells encounter the virus during later infections, the immune system over-reacts.
