Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to a global pandemic with a wide range of symptoms affecting individuals differently. Understanding the symptoms is crucial for diagnosis, treatment, and management of the disease. This article reviews the various symptoms associated with COVID-19, based on recent research findings.

Common Symptoms

Respiratory Symptoms

The most frequently reported symptoms of COVID-19 include respiratory issues such as cough and shortness of breath. Cough is particularly prevalent, with studies indicating that it affects up to 82% of confirmed cases2. Shortness of breath is another significant symptom, often associated with more severe cases of the disease3 6.

Fever and Chills

Fever is a hallmark symptom of COVID-19, reported in approximately 67% of confirmed cases2. Chills often accompany fever and are indicative of the body’s response to the infection3.

Fatigue and Weakness

Fatigue is a common symptom, affecting around 62% of patients2. This symptom can persist even after the acute phase of the illness, contributing to what is known as “long COVID”5.

Headache and Myalgia

Headaches and muscle pain (myalgia) are also frequently reported. Headaches affect about 60% of patients, while myalgia is a common complaint among those receiving treatment for COVID-192 4.

Gastrointestinal Symptoms

Nausea and Diarrhea

Gastrointestinal symptoms such as nausea and diarrhea are less common but still significant. These symptoms are more likely to be reported by patients who have been vaccinated, suggesting a possible link between vaccination status and symptom presentation10.

Neurological Symptoms

Brain Fog and Dizziness

Neurological symptoms, including brain fog and dizziness, have been reported, particularly among healthcare workers who received the mRNA-1273 vaccine4. These symptoms can impact daily functioning and quality of life.

Long COVID Symptoms

Persistent Fatigue and Dyspnea

Long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC), includes symptoms that persist long after the initial infection has resolved. Persistent fatigue and dyspnea (difficulty breathing) are among the most common long-term symptoms5.

Insomnia

Insomnia is another long-term symptom that affects COVID-19 survivors, contributing to overall decreased quality of life5.

Impact of Treatments on Symptoms

Antibody Treatments

Treatments such as bamlanivimab and etesevimab have been shown to reduce the severity and duration of symptoms in patients at high risk for severe COVID-19. These treatments also reduce hospitalization rates and the need for intensive care3 7.

Convalescent Plasma

Convalescent plasma therapy has been evaluated for its impact on symptom resolution. However, studies indicate that it does not significantly accelerate symptom resolution compared to control treatments6.

Vaccination

Vaccination has been associated with a lower viral load and a reduced likelihood of systemic symptoms such as fever, chills, and myalgia. This effect is more pronounced in individuals vaccinated within six months of infection10.

Conclusion

COVID-19 presents with a wide array of symptoms, ranging from respiratory and gastrointestinal issues to neurological and long-term effects. Understanding these symptoms is essential for effective diagnosis and treatment. Ongoing research continues to shed light on the impact of various treatments and the role of vaccination in mitigating symptom severity.
