How does the herpes virus that causes cold sores infect host cells differently than a cold virus would infect host cells?
The herpes that causes cold sores remains in the nervous system and is reactivated from time to time. The sore reappears at this time. A cold virus doesn't act this way in the nervous system. Once a person has a cold, that person makes enough antibodies so that the virus doesn't cause a cold again in that person.
What else can I help you with?
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
Why cant every virus infect every living cell?
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
Why can bacteria infect your cells but you cant infect the bacteria?
Part of the reason is the difference in size. Another is that we consume bacteria but not actually infect them. It is a matter of terminology.
Are viruses always larger than cells they infect?
No, viruses are generally much smaller than cells they infect. Viruses are considered to be submicroscopic in size and are typically measured in nanometers, while cells are much larger and can be seen with a microscope.
Can cancer viruses infect cells if they don't have tails?
Cancer viruses, like all viruses, require specific mechanisms to infect host cells, typically involving the binding of viral proteins to cell receptors. The presence or absence of tails in viruses generally refers to structural characteristics and does not directly determine their ability to infect cells. Many viruses without tails, such as certain types of retroviruses, can still effectively attach to and enter host cells. Therefore, viruses can infect cells regardless of their structural features, as long as they possess the necessary components for attachment and entry.
What is the prognosis for cold sores?
Oral herpes can be painful and embarrassing but, it is not a serious infection. There is no cure for oral herpes, but outbreaks usually occur less frequently after age 35.The spread of the herpes virus to the eyes.can infect the cells in the cornea.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
What did the first viruses do?
Infect cells.
How do bacteria differ from the cells of the organism they infect?
Bacteria are unicellular. The cells of the organism they infect are, quite often, part of a multicellular organism.
Where would viruses most likely grow?
Viruses can only live in living organisms (viruses themselves are not actually living). They might infect cells in our body, such as throat cells (infection of throat cells causes sore throat).
The human immunodeficiency virus may infect what cells?
sperm cells
Why cant every virus infect every living cell?

Is shingles and herpes are same?
Herpes is a family if viruses that cause different diseases. Herpes simplex I is associated with cold sores, herpes simplex II is associated with genital herpes (although those two can be reversed), CMV and EBV can cause mononucleosis and colds and congenital infections in babies as well as cancers, roseolovirus can cause roseola, human herpes virus 8 causes Kaposi's sarcoma and other cancers. The herpes varicella-zoster virus causes chicken pox (varicella). It lies dormant in nerve cells and years later it can reactivate to cause shingles (zoster). So shingles is one example of a herpes virus infection.
What are most viruses highly specific to the cells they infect?
somehow
How do viuses cause disease?
They infect your cells in a certain form.
What type of cells does smallpox infect?
Smallpox usually infects any mouth or throat cells.
