Significant coronavirus symptoms including fever, fatigue, and loss of taste and smell were thought to be genetically determined in 50 per cent of cases, according to data submitted to a symptom tracking app.
Scientists at King’s College London analysed information from 2,600 people who logged their health, symptoms, and level of contact with their twin, on the Covid-19 Symptom Tracker app.
“I would like to say a big thank you to all our twins for logging their symptoms and health status regularly in the app,” said Professor Frances Williams, from King’s College London and TwinsUK.
“It’s because of their tremendous commitment to health research over the years that we are able to carry out this crucial research so quickly.”
The data submitted through the app helped scientists determine how genes influence the symptoms people exhibit.
They noticed that genes were almost 50 per cent responsible for the development of symptoms of delirium, fever, fatigue, shortness of breath, diarrhoea and loss of taste and smell in individuals.
Meanwhile, other symptoms such as hoarse voice, cough, chest pain and abdominal pain were thought to be a result of the surrounding environment.
Some two million people in the UK have downloaded the Covid-19 Symptom Tracker app, which is helping to inform scientists about the virus’s progression, though the number actually using the app fell by almost 75 per cent earlier this month.
However, an analysis of the data published on 8 April suggests coronavirus lockdown is working, with the number of people aged between 20 and 69 who reported Covid-19 symptoms falling from 1.9 million to 1.4 million across the UK.
“It’s essential that everybody keeps logging their health status in the app – even if you feel well,” said Professor Tim Spector from King’s College London. “The data you provide enables us to carry out this urgent research to understand the behaviour and progression of the virus.”
The research has been published online in a pre-print, non-peer-reviewed paper, and it is hoped these findings could provide scientists with an indication on how to go about developing treatments, as well as helping to identify high-risk groups.
NHS England announced 329 hospital deaths from coronavirus on Monday, the lowest such figure since 30 March.
The UK is one of five countries worldwide to have passed the grim milestone of 20,000 confirmed deaths, alongside Italy, the US, France and Spain.
