Fatigue, cough and a sore throat remain the 3 most common symptoms of COVID-19, symptom mapper shows.

In April, Your.MD launched the COVID-19 symptom mapper in partnership with Imperial College London to better understand how the disease is affecting communities worldwide.

The mapper asks users to report when they first had symptoms of COVID-19 and to select the symptoms they’ve experienced from a list known to be associated with the illness.

As of 1 June, more than 90,000 people had used the mapper worldwide, with 3 in 4 reporting at least 1 symptom.

A final sample of 34,921 people was analysed, using data from people who had either tested positive for the disease (1,080), self-diagnosed as having COVID-19 with at least one symptom, or people who had the symptoms of fatigue, cough, fever or loss of smell and taste (anosmia) but self-diagnosed as not having coronavirus. The results showed that people were experiencing a wide range of symptoms.

Wide ranging symptoms and illness duration

The data showed that fatigue, cough and a sore throat were the most commonly reported symptoms, with more than 50% of people experiencing at least 1 of them. Among people who had also tested positive for the virus, over half reported suffering from a headache (58%), muscle ache (56%) and anosmia (53%).

Women reported chills, headache, muscle ache and loss of smell and taste more commonly than men.

Most people had mild symptoms (85%) but this could be because 65% of people who used the symptom mapper were younger than 40. From those included in the analysis, just 1% experienced severe COVID-19.

The length of time people felt ill also varied a lot. The majority of people (58%) had symptoms for a week or less, but around 1 in 10 had symptoms that lasted for over 3 weeks.

What does this mean?

Throughout the pandemic we have seen that people of different ages and gender are experiencing different outcomes from COVID-19 infection, and Your.MD’s results further confirm this.

There aren’t clear-cut symptoms to confirm you have been infected with COVID-19, as the data shows you could experience anything from losing your sense of smell or taste or itchy eyes to shortness of breath, diarrhoea, fever or coughing up mucus.

But the investigation is ongoing, and the greater the sample size, the more we can learn about how the virus is affecting people worldwide. So if you test positive for COVID-19  or believe you may be infected, report your symptoms using Your.MD’s symptom mapper.
