What are the symptoms of COVID-19 that people may ignore?
COVID-19 is notorious internationally as a respiratory infection that may cause fever, cough and dyspnea. But these are not the only symptoms associated with the new coronavirus. Some patients with COVID-19 show less typical symptoms, including nausea, diarrhea, and fowl-like lesions.
"Respiratory symptoms are obviously the most common, but we have also seen symptoms involving other organ systems," said Dr. Eric Cioe-Pena, an emergency physician and global health director at Northwell Health Center in New Hyde Park, New York.
People with atypical infections may also experience more typical symptoms, such as fever, muscle pain, sore throat, and difficulty breathing. However, other people may only have atypical symptoms, and some people who are infected with the virus may not have any obvious symptoms at all.
Cioe-Pena said: "The manifestations of viral infections are very, very extensive. Some people are asymptomatic carriers, and their bodies control the disease very well. Others obviously have very serious systemic symptoms. Then It ’s the rest of the people who are in between ". Understanding some of the less common symptoms may help you identify COVID-19 if you or someone around you is suffering from COVID-19.
Loss of taste or smell
Earlier this month, CDC added "new taste or smell loss" to the COVID-19 symptom list. Scientists at the University of California, San Diego studied the response of 59 COVID-19 patients and found that more than two-thirds of them reported that they lost their sense of taste or smell. Your taste or smell may also be disturbed by other diseases, such as flu or seasonal allergies. But in some cases, this change in sensation may be a warning sign for COVID-19.
Nausea, vomiting or diarrhea
So far, the US CDC has not included nausea or other digestive system discomfort on its symptom list. However, early studies have shown that gastrointestinal discomfort is more common in patients with COVID-19. Recently, the author of a new study from Stanford Medicine reviewed the medical records of 116 patients who tested positive for COVID-19. They found that nearly a third of people have symptoms of the digestive system, including loss of appetite, nausea, vomiting or diarrhea.
Rash, urticaria or fowlpox-like lesions
A dermatologist in Lombardy, Italy, evaluated 88 people who tested positive for COVID-19 and found that about 20% had skin symptoms. These skin symptoms include rash, extensive urticaria, or fowlpox-like lesions.
Robert Glatter, an emergency physician at Lenox Hill Hospital in New York City, said: "Patients may develop skin lesions on the feet or toes, or rashes similar to skin infections. Many rashes may appear as blood clotting or even on the surface of the skin or extremities. Bleeding. "
Madness, dizziness, or muscle weakness
Researchers in the American Medical Association Journal of Neurology (JAMA Neurology) reported that insanity, madness, and other neurological symptoms were also found in some patients with COVID-19. Mild neurological symptoms, such as loss of taste or smell, headache, dizziness, or muscle weakness, can occur early in the onset. More severe neurological symptoms may appear later. "I've seen patients show confusion and changes in mental state." Glatter said. He added: "Some people have (encephalitis) and need to be admitted to the hospital for close nervous system monitoring."
Early reports indicate that COVID-19 may increase the risk of abnormal blood clotting. When a blood clot forms in the small blood vessels of the feet or other limbs, it can cause mild skin symptoms. When a blood clot appears in the lungs, heart, or brain, it can cause more serious complications, such as pulmonary embolism, heart attack, or stroke. "Overall, coagulation seems to be an important issue," said Dr. Maxine Dexter, a lung and critical care specialist at Kaiser Permanente.
She said: "We heard from colleagues in the emergency room that some patients showed symptoms of stroke and heart attack, but in the end they were SARS-CoV-2 positive." If the virus enters heart cells, it will also cause heart infection Myocarditis. This infection may cause chest pain, arrhythmia, and even heart failure. Cioe-Pena said: "Some of the patients we see have this severe coronavirus cardiac manifestation, which is very difficult to control."
Some people who have received COVID-19 treatment have a strange phenomenon, which clinicians call "happy hypoxia". These people have low levels of oxygen in their blood, which usually leads to a loss of consciousness. However, they have been exceptionally alert and comfortable. Reuben Strayer, an emergency physician at the Maimonides Medical Center in New York, said: "What we see on the monitor does not match what the patient looks like in front of us." Some scientists speculate that this phenomenon may be caused by blood in small blood vessels in the lung Caused by clots, but more research is needed to verify this hypothesis.
Virus can be controlled freely
According to Cioe-Pena, the various symptoms associated with COVID-19 are not surprising. Because this coronavirus is new, our body has not established immunity to it. Therefore, "it can control the body freely," Cioe-Pena said. "Once in the lungs and blood, it can easily spread around."
More research is needed to understand how viruses affect different cells in the body. When the virus enters cells in certain organ systems, some symptoms may appear, while other symptoms may be caused by inflammation caused by the body's immune response to infection. "Things are progressing so fast, it is difficult for us to keep up in a short time, and the answers we give may change within a week."
Stop the spread of infection
Considering the wide-ranging impact that a new coronavirus may have, many people may be infected with the virus without realizing it. In order to effectively identify and isolate confirmed cases of infection, Dexter said it is essential to increase the detection of viruses. She said: "When people or their families are diagnosed with infections, they will need to be routinely screened and quarantined." She added: "Until we are able to conduct extensive tests, we will not be able to allow people to safely Back to work. "Currently, Cioe-Pena emphasizes the importance of sustained physical or social distance. "We can't relax the social distance yet. We (in New York) have received encouraging news that the number of new infections has decreased, but this is a direct cause-and-effect relationship of social alienation. But we will not be very Work hard, and then slack off in May to win a medal. "
