Covid-19 Symptom Mapper Results

Last updated 15 June 2020

Background

In April 2020, 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 select the symptoms they’ve experienced from a list known to be associated with the illness.

Data Set

As of 15 June 2020, 105290 people around the world (an increase of 7601 respondents compared with the week commencing 8 June 2020) have used the mapper to record their symptoms, with roughly 3 in 4 people reporting at least one symptom. A final sample of 44567 respondents were analysed. This included people who self-diagnosed as having COVID-19 with at least one symptom, or those who self-diagnosed as not having COVID-19 but experience fatigue, fever, cough and anosmia (loss of smell or taste).

Key Points

Our data showed that fatigue, sore throat and a cough remained the three most common symptoms (54.3%, 48.9% and 48.2% respectively). Among people who had tested positive for the virus, over half reported experiencing headaches (52.3%) and anosmia (49.5%).

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

The majority of people in our sample (85%) had mild symptoms. However, among those who had tested positive for COVID-19, 1 in 3 experienced moderate symptoms.

The length of time people fell ill varied. Over half of the sample had symptoms for a week or less, but around 1 in 10 people reported to have symptoms that lasted more than 3 weeks. A cough, sore throat and fatigue, the three most common symptoms, were also the three most long-lasting.

Countries with the highest number of people with COVID-19 symptoms recorded in the Mapper were India (19.6%), Pakistan (16.2%), the Philippines (11.8%), the UK (10.7%), Mexico (10.7%), Nicaragua (5.3%) and Peru (4.4%).
