Coronavirus is a large family of viruses that can cause disease in animals or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from colds to more serious diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19. The best way to prevent and slow down transmission is to be well-informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol-based rub frequently and do not touch your face.The COVID-19 virus is spread primarily through saliva or discharge from the nose when an infected person coughs or sneezes, so it is important that you also practice breathing etiquette (for example, by coughing into a bent elbow). COVID-19 Antigen Rapid Test is a lateral flow immunoassay intended for the qualitative detection of nucleocapsid protein antigen in direct saliva, nasal swabs or nasopharyngeal swabs from individuals suspected of COVID-19 within the first seven days after symptom onset.
