Insights
This review summarizes COVID-19 (coronavirus disease 2019) manifestations, including typical fever and respiratory symptoms, and atypical presentations. It highlights transmission routes and factors influencing disease severity for better diagnosis and management.
Area of Science:
- Infectious Diseases
- Public Health
- Virology
Background:
- The emergence of SARS-CoV2 in December 2019 led to a global pandemic.
- Understanding COVID-19's diverse clinical spectrum is crucial for effective public health responses.
Purpose of the Study:
- To review and classify the essential clinical manifestations of COVID-19.
- To provide insights into diagnosis and management strategies for improving patient outcomes.
Main Methods:
- A literature review of 59 relevant articles published up to May 1st, 2020.
- Analysis of reported clinical presentations, transmission routes, and factors affecting COVID-19 severity.
Main Results:
- Fever and respiratory involvement are the most common COVID-19 manifestations.
- A wide spectrum of atypical presentations exists, and viral nucleic acid can be found in stool and urine.
- Disease severity varies with patient's medical background, age, sex, and comorbidities.
Conclusions:
- Early recognition of diverse COVID-19 symptoms is vital for timely diagnosis.
- Comprehensive understanding of manifestations aids in tailored patient management and improved outcomes.
- Further research into atypical presentations and long-term effects is warranted.
Abstract:
In December 2019 novel coronavirus-Severe Acute Respiratory Syndrome-Corona Virus2 (SARS-CoV2)-originated from Wuhan, China, and spread rapidly around the world. This literature review highlights the dynamic nature of COVID-19 transmission and presentation. Analyzing 59 relevant articles up to May 1st, 2020 reflects that the main reported clinical manifestation of COVID-19 pandemic is fever and respiratory involvement. Also, current literature demonstrates a wide spectrum of different and atypical presentation(s) of COVID-19. The definite route of SARS-CoV2 transmission is respiratory droplets, however, virus nucleic acid has been detected in the stool and urine specimens as well. The severity of symptoms and outcomes of COVID-19 vary based on the patient's medical background, age, sex, and concurrent medical conditions (e.g. pregnancy). This is the first review that classifies all essential points regarding COVID-19 manifestations at a glance to improve the outcome of the patients by a better insight into diagnosis and management.
