Abstract:
Coronavirus disease 2019 is a rather heterogeneous disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The ongoing pandemic is a global threat with increasing death tolls worldwide. SARS-CoV-2 belongs to lineage B β-CoV, a subgroup of Sarbecovirus. These enveloped, large, positive-sense single-stranded RNA viruses are easily spread among individuals, mainly via the respiratory system and droplets. Although the disease has been gradually controlled in many countries, once social restrictions are relaxed the virus may rebound, leading to a more severe and uncontrollable situation again, as occurred in Shanghai, China, in 2022. The current global health threat calls for the urgent development of effective therapeutic options for the treatment and prevention of SARS-CoV-2 infection. This systematic overview of possible SARS-CoV-2 therapeutic strategies from 2019 to 2022 indicates three potential targets: virus entry, virus replication, and the immune system. The information provided in this review will aid the development of more potent and specific antiviral compounds.
Insights
This review examines therapeutic strategies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It identifies three key targets for developing effective treatments and preventing future outbreaks.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, is a heterogeneous global health threat with significant mortality.
- SARS-CoV-2, an enveloped RNA virus, spreads primarily through respiratory droplets, posing a risk of resurgence upon relaxation of control measures.
Purpose of the Study:
- To provide a systematic overview of potential therapeutic strategies for SARS-CoV-2 infection.
- To identify key targets for the development of novel antiviral treatments and preventative measures.
Main Methods:
- A systematic review of scientific literature published between 2019 and 2022.
- Analysis of therapeutic strategies targeting virus entry, replication, and host immune response.
Main Results:
- Identified virus entry, virus replication, and immune system modulation as primary targets for therapeutic intervention.
- Highlighted the need for potent and specific antiviral compounds to combat SARS-CoV-2.
Conclusions:
- Effective therapeutic options are urgently needed to manage the ongoing pandemic and prevent future outbreaks.
- Targeting specific mechanisms of SARS-CoV-2 infection offers a promising avenue for drug development.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Tumor Immunotherapy
Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
