What is an example of an active virus?
Other viruses are still active and pose a serious threat to an individual’s health. In addition to coronavirus (COVID-19), hepatitis, HIV and the flu still cause mass infection and noticeable death rates.
Is a cold a hidden virus or an active virus?
Summary: An international team of researchers has discovered that respiratory syncytial virus (RSV), a common cold virus causing bronchiolitis in children, can act as a ‘hit and hide’ virus.
Is the influenza virus active or hidden?
Summary: Influenza is able to mask itself, so that the virus is not initially detected by our immune system, a new study shows.
What disease is caused by a hidden virus?
By the 1990s, it was generally understood that HIV replicates vigorously on initial infection and then seems to ‘hide’ for many years, causing few clinical symptoms until AIDS develops.
How does a dormant virus become active?
These dormant viruses can be activated by many factors, such as trauma, another infection, emotional stress, menstruation, excessive exposure to sunlight, and various illnesses.
What is a dormant virus called?
Virus latency (or viral latency) is the ability of a pathogenic virus to lie dormant (latent) within a cell, denoted as the lysogenic part of the viral life cycle. A latent viral infection is a type of persistent viral infection which is distinguished from a chronic viral infection.
What type of virus is the flu?
There are four types of influenza viruses: A, B, C and D. Human influenza A and B viruses cause seasonal epidemics of disease (known as flu season) almost every winter in the United States. Influenza A viruses are the only influenza viruses known to cause flu pandemics, i.e., global epidemics of flu disease.
Can virus lay dormant for years?
Some viruses, like the one that causes chickenpox, can lie dormant in the body for years and later spark another infection or even a different condition.
What are the steps that occur when a hidden virus multiplies?
The one-step multiplication curve for a bacteriophage population follows three steps: 1) inoculation, during which the virions attach to host cells; 2) eclipse, during which entry of the viral genome occurs; and 3) burst, when sufficient numbers of new virions are produced and emerge from the host cell.
What are two illnesses in humans caused by viruses?
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.

What viruses hide in DNA?
Researchers say retroviruses that are dormant in our genome can be triggered by environmental factors and cause diseases such as multiple sclerosis. The human genome is a veritable graveyard of dead retroviruses, making up somewhere between 5 percent and 8 percent of our DNA, according to most credible estimates.
