PCR machines play a crucial role in detecting COVID-19 and other viruses effectively.

Q&A

• Q1: What is PCR?
  A: PCR, or Polymerase Chain Reaction, is a molecular biology technique that amplifies DNA or RNA sequences to detect various pathogens, including viruses.
• Q2: How does PCR detect COVID-19?
  A: PCR detects SARS-CoV-2 RNA in patient samples, typically through nasopharyngeal swabs.
• Q3: Are there different types of PCR tests?
  A: Yes, there are several types, including qualitative, quantitative, and reverse transcription PCR (RT-PCR) specifically for RNA viruses.
• Q4: Is PCR effective for detecting other viruses?
  A: Yes, PCR can effectively detect many viruses, including influenza, HIV, and hepatitis B and C.
