The common cold and even the flu that interfere with normal breathing are considered respiratory infections –usually caused by pathogens that attack the respiratory tract. Respiratory infections are contagious and can spread from one person to another by transmitting germs from a cough or sneeze or even touching an object exposed to those germs.
 Respiratory infections can lead to a variety of symptoms, including: congestion, runny nose, cough, sore throat, body aches, fatigue, etc. Some could cause life-threatening like bacterial pneumonia or tuberculosis (TB). The real-time PCR kits developed by Dana Gene for detecting the nucleic acid of respiratory infection could assist in the diagnosis of respiratory infection, and monitor the efficacy of drug. Compared with the traditional methods, real-time fluorescent quantitative PCR kits are more accurate, rapid and reliable.
