Abstract:
The novel human coronavirus, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), which results in the coronavirus disease 2019 (COVID-19), has caused a serious threat to global public health. Therefore, many studies are performed on the causes and prevalence of this disease and the possible co-occurrence of the infection with other viral and bacterial pathogens is investigated. Respiratory infections predispose patients to co-infections and these lead to increased disease severity and mortality. Numerous types of antibiotics have been employed for the prevention and treatment of bacterial co-infection and secondary bacterial infections in patients with a SARS-CoV-2 infection. Although antibiotics do not directly affect SARS-CoV-2, viral respiratory infections often result in bacterial pneumonia. It is possible that some patients die from bacterial co-infection rather than virus itself. Therefore, bacterial co-infection and secondary bacterial infection are considered critical risk factors for the severity and mortality rates of COVID-19. In this review, we will summarize the bacterial co-infection and secondary bacterial infection in some featured respiratory viral infections, especially COVID-19.
Insights
Bacterial co-infections and secondary bacterial infections are critical risk factors for COVID-19 severity and mortality. This review summarizes bacterial co-infections in respiratory viral infections, particularly SARS-CoV-2.
Area of Science:
- Infectious Diseases
- Microbiology
- Public Health
Background:
- Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) causes COVID-19, a global health threat.
- Respiratory infections increase susceptibility to co-infections, worsening disease severity and mortality.
- Bacterial co-infections are significant risk factors for COVID-19 severity and mortality.
Purpose of the Study:
- To review bacterial co-infection and secondary bacterial infection in respiratory viral infections.
- To highlight the impact of bacterial co-infections on COVID-19 outcomes.
Main Methods:
- Literature review of bacterial co-infection in respiratory viral infections.
- Focus on studies investigating co-infections in SARS-CoV-2 patients.
Main Results:
- Viral respiratory infections, including COVID-19, can lead to bacterial pneumonia.
- Bacterial co-infections may contribute to mortality in some COVID-19 patients.
- Antibiotics are used to manage bacterial co-infections in SARS-CoV-2 patients.
Conclusions:
- Bacterial co-infection is a critical factor influencing COVID-19 severity and mortality.
- Understanding and managing bacterial co-infections is crucial for improving patient outcomes in viral respiratory infections.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
