We’ve written previously about a lesser known COVID-19 symptom to look out for. But as experts learn more about COVID-19, new symptoms of the infection are coming to light. In addition to fever, coughing and difficulty breathing, plus a sudden loss of smell or taste (as per our above-referenced post), some people with COVID-19 have also presented with less typical symptoms, including nausea, diarrhea, delirium, chickenpox-like lesions, and more. Indeed, according to a study by Stanford Medicine, which analyzed the medical records of 116 patients who had tested positive for COVID-19, almost a third displayed digestion related symptoms, including loss of appetite, nausea, vomiting, and diarrhea. Meanwhile, a study in Italy that looked at 88 patients who has tested positive for COVID-19 found that approximately 20% displayed skin symptoms, including a red rash, widespread hives, or chickenpox-like lesions. While people with atypical COVID-19 symptoms may also develop more classic symptoms too, not all will. And then there are the individuals who contract the virus and don’t have any symptoms at all i.e. are asymptomatic. This is why it is useful to spread awareness about some of the less common COVID-19 symptoms, so that people can potentially spot if they or someone they know develops the disease.
It’s impossible to turn on the news at the moment and not be greeted with updates about the coronavirus disease, COVID-19. The problem, however, with so much news coverage is that it can be difficult to discern which pieces of information are true and which are simply myths. To help provide some clarity, we have compiled this list of coronavirus myths: Myth 1. Children cannot catch the new coronavirus (SARS-CoV-2) While the majority of coronavirus cases have been in adults, people of any age can become infected with SARS-CoV-2. What is true is that adults with several pre-existing health conditions are more likely to become severely ill. Myth 2. COVID-19 is just like the flu While COVID-19 causes many symptoms that could be described as ‘flu-like’ and both illnesses can lead to pneumonia, the overall profile of COVID-19 is more serious than ordinary flu. While the actual mortality rate of COVID-19 remains unclear, it is expected to be many times higher than that of seasonal flu. Myth 3. Antibiotics kill coronavirus COVID-19 is caused by SARS-CoV-2, a virus. Antibiotics only kill bacteria, so they are all but useless against the new coronavirus. Myth 4. Thermal scanners can diagnose coronavirus The only thing that thermal scanners can detect is an elevated body temperature (a fever). While this is one of the symptoms of COVID-19, it cannot be used to diagnose the disease alone. Myth 5. Face masks protect against coronavirus Wearing a face mask is not guaranteed to protect you from SARS-CoV-2 – especially if the face mask is ill-fitting. Where face masks can make a real difference is when they are worn by people with the virus, as they can help prevent others from becoming infected.

While fever, tiredness and a dry cough are the most common symptoms associated with COVID-19, the respiratory illness caused by the new SARS-CoV-2 coronavirus, evidence is beginning to show that a sudden loss of smell or taste could also be a sign. The latest researchers to report that a loss of smell and taste could be associated with COVID-19 are a team from King’s College London. They looked at responses from more than 400,000 people with suspected COVID-19 symptoms who entered how they were feeling into an app. Of the people who had tested positive for COVID-19 (579 individuals), three-fifths (59%) reported a loss of smell or taste. While a loss of smell or taste have not yet been added to the official list of COVID-19 symptoms published by the NHS or Public Health England, it is important to note that the current situation is rapidly evolving and this could change at any time. The King’s College researchers say that a loss of smell or taste should not be used on their own, but could be useful when considered alongside other important symptoms such as a dry cough and fever. Speaking about their findings, lead researcher Professor Tim Spector said: “When combined with other symptoms, people with loss of smell and taste appear to be three times more likely to have contracted Covid-19 according to our data, and should therefore self-isolate for seven days to reduce the spread of the disease.” [Related reading: Why social distancing is crucial for reducing the spread of COVID-19]
