To determine: The reason for the fact that antibiotics fail to produce any significant effect against the viral infections.
Introduction: Mostly bacteria or virus cause human infections. The virus enters the human body through contaminated food, close contact with an infected person, and other similar routes. Antibiotics are medicines that fight against infections.
Explanation of Solution
Antibiotics are effective against bacterial infections, but will not have any effect on viral infections. Antibiotics fight against the bacterial infection by either keeping them from reproduction or destroying them.
Viruses are microscopic organisms that cannot replicate without the host. Viruses cannot do anything until they enter a host cell and are considered as technically not alive. Antibiotics cannot fight against the virus in the same way they fight against bacteria. Hence, antibiotics do not produce any significant effect against viral infections.
To determine: The advice that can be given to an entry-level high school student and a third-grade student to fight against the viral infection and to recover quickly.
Introduction: Viruses cause infectious diseases such as flu, warts, Ebola, smallpox, and HIV/AIDS. Viruses can be transmitted to humans through contaminated food, close contact with an infected person, and other similar routes.
Explanation of Solution
The following are the advice that can be given to an entry-level high school student to fight against the viral infection and to recover quickly:
- • Antiviral medicines can reduce the symptoms of viral infection and also inhibit the spread of the viruses.
- • Vaccines can reduce the risk of viral infection by inducing the production of antibodies against specific viruses. Antibodies are the most critical part of the immune system as they neutralize the pathogens such as pathogenic viruses and bacteria.
The following are the advice that can be given to the third-grade student to fight against the viral infection and to recover quickly:
- • The antiviral medicines can be used to prevent the growth of viruses in the body and also to help the people to get over the viral infection faster.
- • There are vaccines also that can be used to increase the production of antibodies. Antibodies attach to specific viruses and keep them from attaching to the cells in the body.

- Answer the following 1.Are viruses living or non-living organisms? 2. What is the difference between HIV and AIDS? 3. HIV is classified as a retrovirus. What are retroviruses? 4. In your own words, provide a short summary of the HIV replication cycle. 5. Why is reverse transcriptase an important enzyme in the replication cycle of HIV? 6. In the chapter about enzymes, we have discussed how drugs are basically inhibitors. There are currently a multitude of Antiretroviral therapy (ART or ARV) options available to people living with HIV (PLHIV) so that the viral replication is suppressed and does not progress to AIDS. What do you think these drugs target? Discuss briefly. 7. SARS-CoV-2, the virus that causes CoVid-19, belongs to the Coronaviridae family. Viruses under this family have a genome made of single-stranded positive-sense RNA. Is this similar to the viral genome of HIV? If so, do you think that – in theory – they would have similar replication cycles? 8.
