Loss of Sense of Smell Could Be Early Sign of Coronavirus Infection

"People hadn't been talking about it [as a symptom], so I wasn't looking out for it".

However, new reports from doctors across the United States reveal a somewhat unique symptom that appears to be popping up with increasing regularity in confirmed coronavirus cases: A loss of smell.

On Friday, British ear, nose and throat doctors warned adults whose sense of taste and smell have deteriorated to isolate themselves for seven days, even if they are not experiencing other coronavirus symptoms, such as fever, fatigue, coughing or difficulty breathing.
Kumar was quoted by Sky News as saying. "And this is just the tip of the iceberg". The conditions, which are called anosmia for a lack of smell and dysgeusia, for a lack of taste, have been found in patients who tested positive but have displayed no other signs of Covid-19 symptoms. Because the virus is known to replicate in a patient's respiratory tract, they also advise against performing sinus endoscopy procedures on anyone in order to prevent a potential infection with SARS-CoV-2 (the coronavirus that causes COVID-19). The letter, signed by Kumar and sent to public health authorities, urged doctors treating people with anosmia to don personal protective equipment while treating them.

According to them, many patients around the world who have tested positive for coronavirus are only showing symptoms of loss of smell and taste, while missing more commonly recognized symptoms of high fever and coughing, reports Business Insider.

Van Kerkhove said a number of countries were collecting data on the symptoms of early infections, and that World Health Organization is working to learn if they have identified the loss of smell or taste as a symptom. "It is a dramatic indicator". "I have personally seen four patients this week, all under 40, and otherwise asymptomatic except for the recent onset of anosmia". "Therefore, there are lots of carriers around".

"We really want to raise awareness that this is a sign of infection and that anyone who develops loss of sense of smell should self-isolate", Prof Claire Hopkins, president of the British Rhinological Society, wrote in an email to the New York Times. But in cases of the pandemic virus, it looks more like a temporary effect. "But these viruses, which are obviously very, very small particles, go into the roof of the nose".

But this coronavirus is a tiny particle so it can reach that area, and it actually affects the lining and the receptors in the roof of the nose. But Hopkins raised concern at the number of COVID-19 patients who were otherwise asymptomatic.

"I wouldn't use it alone [to screen patients], but I think if it's added to some of the other symptoms, it adds to the possibility", said Holbrook. "Due to the speed, it is hard to obtain rigorous clinical information that helps in the prevention and treatment of the disease, but it also requires us, as health professionals, to take measures that reduce or prevent the spread of the disease, with the possible evidence under these circumstances".

However, now in Australia, you do not meet the criteria for COVID-19 testing if you have lost your sense of smell. He immediately chose to self-isolate and tell his employer.

It is important to note that a reduction in one's sense of smell is a relatively common symptom associated with a number of viral and bacterial infections, from the flu to sinusitis. "And in South Korea and all these other countries that are, you know, weeks, maybe even a month or two ahead of us are constantly feeding us information".
