COVID-19 is still very present in people's daily lives. Unfortunately, this pandemic has claimed many victims around the world and experts continue to investigate this highly contagious virus.
Since the arrival of COVID-19, many symptoms have been attributed to it. Fever, cough and loss of smell are part of the classic triad of symptoms of this disease. However, a new study has focused attention on the other symptoms of this coronavirus that may reveal an additional one-third of cases.
As reported by King's College London in their research, one third of those infected with COVID-19 did not experience any of the three usual symptoms during the first few days of infection.
This study, conducted on 122,000 adults in the United Kingdom using the 'ZOE COVID Symptom Study' app, revealed that limiting detection to cough, fever and anosmia only revealed 69% of cases. If this list of symptoms is extended to seven, 96%would be detected.
The symptomatology on which this study has focused attention, in addition to the classic triad, has to do with fatigue, headache, diarrhea and sore throat.
These symptoms had already been identified as being associated with SARS-CoV-2. In fact, the Spanish Ministry of Health had already identified them in a long list but had listed them as infrequent. Now, the British study highlights them as important.
This research by King's College London has uncovered that some of these symptoms appear first. Headache and diarrhea would occur in the first three days of infection, while fever would occur up to the seventh. In fact, 31% of people infected with COVID-19 had no fever, cough or anosmia in the early stages of infection, when the virus is most transmissible.
