PCR is one of the most widely used laboratory methods for detection of viral nucleic acids. PCR analysis can also be used to determine viral RNA, by adding an initial step in which the RNA is converted into DNA; know as reverse transcriptase PCR (RT-PCR).

What is the most effective protection against viral infections? ›

Immunoprophylaxis against viral illnesses includes the use of vaccines or antibody-containing preparations to provide a susceptible individual with immunologic protection against a specific disease. Immunization against viral illnesses can be either active or passive.

Based on their host, viruses can be classified into three types, namely, animal viruses, plant viruses, and bacteriophages.

Data protection is the process of safeguarding important data from corruption, compromise or loss and providing the capability to restore the data to a functional state should something happen to render the data inaccessible or unusable.
