Question

Which of the following viruses is not transferred through the semen of an infected male?
A. Chikungunya virus
B. Ebola virus
C. Hepatitis B virus
D. Human immunodeficiency virus

Answer 1

Hint: Chikungunya is a viral infection outspread by the bite of an infected mosquito to humans. It is due to a virus called chikungunya (CHIKV). The mosquito could catch the virus once it ingests the blood when an uninfected mosquito feeds on an individual (someone who has the virus circulating in their blood).

Complete solution:
CHIKV can be transmitted more rapidly to a young host than other mosquito-borne viruses. Laboratory studies have shown that viruses can be found in saliva as early as 2-3 days after a meal of blood, which means that the complete period of transmission between humans to mosquitoes and back to humans would occur in less than a week. The mosquito, once transmitted, is believed to be able to transmit the virus for the rest of its lifespan. Most notably, Aedes aegypti and Aedes albopictus are involved in the transmission of CHIKV. Ebola virus disease is a rare but severe, often lethal disease in humans, commonly known as Ebola haemorrhagic fever. Ebola is primarily spread by infected individuals by close contact with blood or other body fluids. In human semen, protein residues called amyloid fibrils massively boost infection of the Ebola virus protect the virus from adverse environmental conditions such as heat and dehydration. A severe hepatitis B virus infection of the liver can be easily addressed by a vaccine. The virus is passed by blood, semen or other body fluids from person to person. It is spread through direct contact with infected body fluids, primarily by damage to the needle stick or sexual activity. HIV produces AIDS and disrupts the capacity of the body to combat infections. Via interaction with contaminated blood, semen or vaginal fluids, the virus may well be transmitted.
So, the correct answer is option A.

Additional Information: It has not been reported that the Ebola virus is transmitted by food. However, through the processing and consumption of wild meat products or shot wild animals infected by Ebola, the Ebola virus could spread. There is no documentation of the Ebola virus being transmitted by mosquitoes or other organisms. There is still a safe and effective vaccine available that offers 98-100 percent safety against hepatitis B virus Stopping infection with hepatitis B restricts the occurrence of complications, such as the development of chronic diseases.

Note: In infected individuals, the clinical manifestations by chikungunya are fairly mild and the infection may be unnoticed or misdiagnosed. During the day, when they have a virus residing in their blood and if a mosquito feeds on them, the mosquito will suck up the virus, and the infection process begins again.
