Hint:- The infections which are caused by the microorganisms, named viruses are called viral diseases. The viral infection spreads From one individual to another by contamination (breathing, sneezing, coughing, etc). The virus can’t multiple without a host body. Many several viral infections occur in humans, named herpes, mumps, HPV, etc.
Complete Answer:-In the given question,
Dengue is also called break-bone fever which is caused by the virus called dengue virus. There are four types of dengue viruses found. These are DENV-1, DENV-2, DENV-3, DENV-4. These viruses need a vector to infect a healthy person. In this case, the Aedes mosquito plays the role of the vector. When a female Aedes mosquito bites an infected person the dengue virus enters into the mosquito through the blood. When the mosquito carrying dengue virus bites an uninfected individual, the virus enters into the healthy person and starts to replicate. The symptoms of dengue are similar to flu which include fever, headache, vomiting, joint pain, etc.
AIDS or Acquired Immunodeficiency Syndrome is caused by a virus called the Human immunodeficiency virus (HIV). This virus is a Life-threatening virus that is causing damage to the immune system of the body. HIV spreads in contamination of body fluids like blood, vaginal discharge, semen, etc. The HIV-infected person remains asymptomatic at the initial stage. In late-stage, the person includes several symptoms like weight loss, fever, weakness, fatigue, etc.
Salmonella typhi is a bacteria that causes typhoid disease. This infection mainly occurs in children. The spreading of typhoid involves the contamination of infected individuals or bacteria-contaminated food and water. The symptoms of typhoid involve pain in the stomach, headache, fever, diarrhea, etc. So typhoid is not caused by viruses.
Influenza virus causes a disease called influenza or flu. This is the most commonly found viral infection. The symptoms which are caused by the influenza virus are a fiver, coughing, sneezing, headache, joint pain, etc.
Hence, the correct answer is option C. Typhoid.
Note:- Viruses are small organisms that contain a genetic material, enclosed in a protein coat. The virus enters into the normal cells of a healthy organism and produces multiple of its copies by using the cells of the host. In many cases, the immune system of the body can destroy the virus but in other cases, medical help is needed to recover the body. The treatment is done by using antiviral medicines.
