RT PCR Line List Download: What Is It and How to Do It?
If you are an epidemiologist or a public health professional, you may have heard of or used the term "RT PCR line list download". But what does it mean and how do you do it? In this article, we will explain what RT PCR is, what a line list is, why RT PCR line list download is important, and how to do it step by step.
What is RT PCR?
RT PCR stands for reverse transcription polymerase chain reaction
RT PCR is a laboratory technique that combines two processes: reverse transcription and polymerase chain reaction. Reverse transcription converts RNA (ribonucleic acid) into DNA (deoxyribonucleic acid), while polymerase chain reaction amplifies or copies specific DNA segments. By using these two processes together, RT PCR can detect very small amounts of genetic material from viruses or other microorganisms.

RT PCR is used for diagnosis and quantification of viral infections such as COVID-19
RT PCR is one of the most widely used methods for diagnosing viral infections such as COVID-19, the disease caused by the novel coronavirus SARS-CoV-2. By targeting specific genes or regions of the viral genome, RT PCR can identify the presence or absence of the virus in a sample, such as nasal swab or blood. RT PCR can also measure the amount or load of the virus in a sample, which can indicate the severity or stage of infection.
What is a line list?
A line list is a table that contains key information about each case in an outbreak
A line list is one type of epidemiologic database that organizes data from an outbreak investigation. A line list consists of rows and columns, with each row representing a case or an individual who has been diagnosed with or suspected of having the disease under investigation, and each column representing a variable or a characteristic of the individual, such as age, sex, symptoms, exposure history, test results, etc.
A line list is organized by rows and columns, with each row representing a case and each column representing a variable
A line list can have different types of variables, such as categorical, numerical, ordinal, or binary. For example, a categorical variable can be the sex of the case (male or female), a numerical variable can be the age of the case (in years), an ordinal variable can be the severity of the symptoms (mild, moderate, or severe), and a binary variable can be the test result (positive or negative). A line list can also have derived variables, such as the incubation period (the time between exposure and onset of symptoms) or the case fatality rate (the proportion of cases who died).
A line list describes an outbreak in terms of person, place and time
A line list is a useful tool for describing and analyzing an outbreak in terms of person, place and time. By looking at the variables in a line list, epidemiologists can answer questions such as: Who is affected by the outbreak? Where did the outbreak occur? When did the outbreak start and end? What are the common features or risk factors of the cases? How is the outbreak evolving or changing over time? These questions can help epidemiologists to understand the source, mode of transmission, and extent of the outbreak, and to formulate hypotheses and test them.
Why is RT PCR line list download important?
