The most common role of a virus in making vaccines is injection of a live weaken form of the virus. This virus will reproduce poorly once inside the body.
When you get infected with HIV, the virus enters your blood and gets inside your cells that are floating around
A foodborne virus can only reproduce inside the body of a living host, such as a human or animal. Once ingested, the virus can multiply in the host's cells and cause illness.
The human body detects the Nipah virus through the immune system's response to the virus entering the body. Once the virus breaches the body's defenses, the immune system produces antibodies to fight the infection and trigger an inflammatory response. This process helps the body recognize and eradicate the Nipah virus.
Viruses reanimate dead cells in the body by hijacking the cellular machinery of living cells. Once inside a cell, the virus uses the cell's resources to replicate itself, leading to the destruction of the host cell. This process allows the virus to spread and infect other cells, ultimately causing harm to the body.
A virus can enter the body in different ways, like when we breathe in tiny droplets from someone who is sick or touch surfaces where the virus has landed. Once inside, the virus finds a way to get into our cells, which are like tiny building blocks of our body. It then makes copies of itself, which can make us feel unwell. That's why it's important to wash our hands and stay away from sick people!
To get sick with a virus, you typically need to be exposed to the virus itself, which can occur through direct contact with an infected person, contaminated surfaces, or respiratory droplets. The virus must then enter your body, often through the respiratory tract, mucous membranes, or breaks in the skin. A weakened immune system or underlying health conditions can increase susceptibility to infection. Once inside, the virus can replicate, leading to illness as your body responds to the infection.
Viruses do not have a habitat in the traditional sense, as they are not considered living organisms. They require a host cell to replicate and survive. Once inside a host, viruses can exist in various parts of the body, depending on the type of virus and its specific target cells.
Vaccines contain an inert or inactive version of a virus. When the body detects it, it develops anti-bodies to the inert virus in the vaccine. So when the real virus shows up, the body recognizes it, and can easily defeat it.
I'm not sure this is also for bacteria, but when a virus enters a host, it travels to a nearby cell and attaches to it and fuses a chemical into it containing its DNA. Once inside, the DNA duplicates over and over making copies of that virus until the cell explodes releasing the new virus' and they repeat the process. You cannot kill a virus with medicine since it is not a living thing. Bacteria on the other hand is a living thing.
HIV is a virus, and can't be removed from the body once infected.
i dont really no
