A pandemic of respiratory disease spreading from person-to-person caused by a novel (new) coronavirus. The disease has been named "coronavirus disease 2019" (abbreviated "COVID-19"). This situation poses a serious public health risk. There is a sudden spurt of cases of fever with cough of unknown etiology. 1% of the cases land up with pneumonia. Within a matter of weeks the infection has spread to neighboring countries. Outline the standard tests for investigation of the outbreak.

The outbreak of a novel respiratory disease like COVID-19 caused by a new coronavirus requires swift and comprehensive action to contain its spread and protect public health. Early detection of the pathogen and understanding its epidemiology are key to managing such a situation. A well-organized response involves systematic investigation using standard tests to confirm the presence of the virus, assess its characteristics, and understand its transmission dynamics. The following outlines the standard tests and diagnostic procedures used to investigate an outbreak like COVID-19:

### 1. Clinical Evaluation and Epidemiological Surveillance

Before laboratory-based diagnostic tests are performed, a clinical assessment of individuals is essential. Healthcare providers must identify individuals presenting with typical symptoms, such as fever, cough, and respiratory distress, which may suggest a viral infection like COVID-19. Epidemiological data, including travel history to affected areas or contact with confirmed cases, also play a crucial role in assessing the likelihood of infection.

The initial clinical suspicion can be confirmed through patient history, travel or exposure risk, and symptoms. However, to conclusively identify the pathogen, laboratory testing becomes necessary.

### 2. Real-Time Reverse Transcription Polymerase Chain Reaction (RT-PCR)

RT-PCR is the gold standard for diagnosing COVID-19 and is widely used to confirm the presence of the novel coronavirus (SARS-CoV-2) in respiratory samples. This test detects viral RNA in respiratory tract specimens such as nasopharyngeal or oropharyngeal swabs, sputum, or bronchoalveolar lavage (BAL) fluid.

#### Procedure:
- Sample Collection: A healthcare worker collects a sample from the patient’s nose or throat using a swab. This sample is crucial for accurate detection of the virus.
- RT-PCR Process: The sample is processed in a laboratory where viral RNA is extracted. Using reverse transcription, the RNA is ____ ___ ____ ______ _____ _____ ____.
