Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms..

What diseases can be treated with viruses?
However, the treatment of viral infections has proved more challenging. For some viral diseases, such as herpes simplex virus infections, HIV/AIDS, and influenza, antiviral medications have become available, but drug-resistant microbes have been created as a result.
Which diseases are not caused by viruses?
Which of the following diseases is not caused by virus?(1) Mumps(2) AIDS(3) Tuberculosis(4) Rabies. Answer: (3) Viruses cause the disease such as mumps, rabies, and AIDS. Tuberculosis is an infectious disease produced by the tuberculosis bacterium Mycobacterium.
Which of the following is caused by bacterial infection?
Infectious diseases can be caused by: Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.
What are the 4 types of infections?
Types of infectionsViral infections. Viruses are very tiny infectious organisms. … Bacterial infections. Bacteria are single-celled microorganisms. … Fungal infections. Fungi are another diverse group of organisms that can include things like yeasts and molds. … Parasitic infections. … Prions.
What are two illnesses in humans caused by viruses?
Common examples of contagious viral diseases include the flu, the common cold, HIV, and herpes. Other types of viral diseases spread through other means, such as the bite of an infected insect.
How do you kill a virus in your body?
Our bodies fight off invading organisms, including viruses, all the time. Our first line of defense is the skin, mucous, and stomach acid. If we inhale a virus, mucous traps it and tries to expel it. If it is swallowed, stomach acid may kill it.
How long is a virus contagious for?
Most people will be infectious for around 2 weeks. Symptoms are usually worse during the first 2 to 3 days, and this is when you’re most likely to spread the virus.
How do you get rid of a viral infection?

How long do viruses last?
The life of a virus (technically, viruses are not alive) depends on what type of virus it is, the conditions of the environment it is in, as well as the type of surface it is on. Cold viruses have been shown to survive on indoor surfaces for approximately seven days. Flu viruses, however, are active for only 24 hours.

How is influenza caused?
What Causes the Flu? The flu is caused by influenza viruses that infect the nose, throat, and lungs. These viruses spread when people with flu cough, sneeze or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby.
Is the flu a disease or virus?
Flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs.
How do viruses infect the body?
Viruses infect a host by introducing their genetic material into the cells and hijacking the cell’s internal machinery to make more virus particles. With an active viral infection, a virus makes copies of itself and bursts the host cell (killing it) to set the newly-formed virus particles free.
Is a virus a disease or infection?
Viral Infections Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, Ebola, and COVID-19. Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves.
Why do viruses make us sick?
Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system’s antibodies and other cells to target the invader.
