The disease caused by the new SARS-CoV-2 coronavirus can cause a wide variety of signs and symptoms. The most common are fever, cough, sore throat and tiredness; Other symptoms may be shortness of breath or shortness of breath, muscle aches, chills, headache or chest pain. Loss of taste or smell, which could be an early indicator of infection and usually resolves within 14 days, has also been incorporated into the definition of a suspected case for some time, although there are people in whom it lasts longer weather. At the other extreme are people who pass the infection without even realizing it, because show no symptoms.
However, explains William F. Marshall, infectious disease expert at the Mayo Clinic (Rochester, United States), Covid-19 disease can also cause perhaps less predictable symptoms, including:
Covid-19 may cause mild gastrointestinal symptoms, including loss of appetite, nausea, vomiting, and diarrhea. These symptoms may only last a day. Some people with Covid-19 have diarrhea and nausea before developing fever and respiratory symptoms.
Younger people with a less severe condition may develop painful itchy, chilblain-like lesions on the hands and feet, an inflammatory skin condition. This symptom, often called “COVID fingers,” usually lasts for about 12 days. The disease was also reported to cause small, itchy blisters that usually appear earlier than other symptoms and last for about 10 days. Others may develop hives or rashes with raised or flat skin lesions. These skin changes can last for a week, appear simultaneously with other symptoms, and are associated with more serious infections.
It was also reported that coronavirus infection can cause confusion in the elderly, particularly in those who are in severe conditions.
The disease can cause eye problems such as dilation and redness of blood vessels, swelling of the eyelids, excessive tearing and increased secretions. The infection can also cause mild sensitivity and irritation. These symptoms are more common in people with serious infections.
Signs and symptoms can appear two to 14 days after exposure to the virus (usually appear around 5 days) and can range from mild to severe. The specialists insist on not underestimating them and, when suspected, isolate themselves and contact the health system.
