Pertussis (pertussis) is a highly ↔∏contagious acute respiratory dis×≈☆ ease mainly caused by B. pertus♦ 'δsis infection. The cough g•"φradually worsened, showing a typical parox$♦₹≥ysmal and spastic cough. At the end of the cough,☆☆ a deep and long chicken-like inspi☆§✔ratory roar appeared, and the total numbe>>≤₹r of white blood cells a© λnd lymphocytes increased.&'★₽×nbsp;Pertussis can cause a series÷♣ of serious complications such a☆≈s pneumonia and pertussis encephalopa÷±thy, and endanger the health of newbo♠✔rns.
Clinically, bacterial culture and ser<€ological screening are commonly used to detect' ε B. pertussis, but the isolation and " cultivation of B. pe"♣₽rtussis is difficult and the culture cyc××β®le is long. Serologi✔•↔↑cal screening has the defects of lo"±w sensitivity and low±™ specificity, which limits the above C✔"↓γlinical application of two detection m¥♣ethods for pertussis bacteria.✔ ♠ "Expert Consensus o±★€n the Diagnosis and Tre✘≥§'atment of Chronic Weσ♥t Cough in Chinese Childreσππn (2019 Edition)" proλ♥≈posed "Pertussis PCR detection has h← $igh sensitivity and "® can be diagnosed early". Therefor≤π≈•e, the detection of pertussis nucleic acid can de≤↓→tect the cause of cough as early γγas possible; accurately guide the use of ant×★ibiotics, reduce drug abuse, and reduce comp×₽εlications; prevent and control infectio↔ n early.
