Superinfection is the process by which a cell that has previously been infected by one virus gets co-infected with a different strain of the virus, or another virus, at a later point in time. [3] In some cases viral superinfections may be resistant to the antiviral drug or drugs that were being used to treat the original infection.

抗菌药物 的使用可致 菌群 改变，使耐该种抗菌药物的微生物引发新的感染。 引起新感染的细菌可以是在正常情况下对身体无害的寄生菌，由于菌群改变，其他能抑制该菌生长的无害菌为药物所抑杀后转变为致病性菌，或者也可以是 原发感染 菌的 耐药菌株。 但是，当长期、大量使用广谱抗菌药物时，情况就发生了根本的改变：使原本并不致病的微生物增殖机会大增，也可以导致人体发生感染，尤其对 抵抗力 低下的病人，如 癌症 患者、 肺心病 患者，以及老、幼、病、残者更是 …

Many viruses implement measures to prevent infected cells from being further infected by another virus, a phenomenon known as superinfection exclusion. For VACV, two sets of protein pairs on the plasma membrane of VACV-infected cells effectively prevent superinfection.

Here, we assessed the incidence of bacterial superinfection, including new episodes of pneumonia, urinary tract infection (UTI), bacteremia, or other infections, and those of multidrug-resistant pathogens and determined their effects on clinical outcomes in critically ill patients with severe COVID-19 pneumonia who require ICU admission. 2.

A superinfection is one in which the individual has a prior infection with HBV, usually a chronic infection, and is then infected with HDV. Such superinfections have a much greater chance of being more extensive and also a greater chance of going on to chronicity.

二重感染（Superinfection）又称重复感染，是指长期使用广谱 抗生素，可使敏感菌群受到抑制，而一些不敏感菌（如真菌等）乘机生长繁殖，产生新的感染的现象。

2024年10月30日 · Superinfections occur when an additional infection develops on top of an existing one, complicating treatment and worsening patient outcomes. These infections can involve viruses, bacteria, or fungi and are often linked to weakened immune systems or disrupted microbial balances due to prior medical interventions.

2023年12月7日 · Learn about superinfection, a condition where a person develops a new infection while already infected with another pathogen, and find out its causes, symptoms, and treatment options.

重复感染（superinfection）是指感染尚在进行中，同一种病原体再度侵袭而又感染。
