A recent study found that there are 6 types of Covid-19 disease caused by the outbreak of the emerging coronavirus "SARS Cove 2", so what are they?
The study was led by researchers from King's College London, and published on the King's College London website.
The researchers found that each type of infection with Covid-19 is characterized by a specific set of symptoms, and that each type differed in the severity of the disease and the need to provide support to the patient's respiratory system during the recovery phase.
The researchers used the machine learning algorithm to analyze data from about 1,600 users in the United Kingdom and the United States who were infected with Covid-19 and recorded their symptoms regularly using an application last March and April, then a thousand users last May, and the analysis revealed 6 specific groups of Symptoms.
Despite persistent coughing, fever, and loss of sense of smell, which are usually considered as the three main symptoms of Covid-19, data gathered from users of the application show that a wide range of different symptoms can appear including headache, muscle pain, fatigue, diarrhea, loss of appetite, and shortness of breath.
The disease also varies greatly between people, from mild influenza-like symptoms to severe illness to death.
The six types of Covid-19 disease are:
The first type: influenza-like, but without flu-like with no fever, and symptoms of headache, loss of sense of smell, muscle pain, cough, sore throat, and chest pain.
The second type: flu-like, but with fever and loss of appetite (flu-like with fever) and symptoms of headache, loss of sense of smell, cough, sore throat and hoarseness.
The third type: gastrointestinal, where the patient suffers from diarrhea, with symptoms of headache, loss of smell, loss of appetite, sore throat, chest pain and without coughing.
The fourth type: severe level one with fatigue, headache symptoms, loss of smell, cough, fever, hoarseness and chest pain.
Fifth type: severe level two, confusion, fatigue, headache, loss of smell, loss of appetite, coughing, fever, hoarseness, sore throat, chest pain and muscle pain.
Type VI: severe level three abdominal and respiratory, in which a person develops shortness of breath, diarrhea, severe abdominal pain with a headache, loss of smell, loss of appetite, coughing, fever, hoarseness, pain in the throat, chest pain and fatigue Muscle confusion and pain.
The researchers also found that the possibility of the patient in each of the six groups needing respiratory support, such as oxygen or placing on a ventilator, is the following:
- The first type: 1.5%.
- The second type: 4.4%.
- The third type: 3.3%.
- The fourth type: 8.6%.
- Fifth type: 9.9%.
- Type VI: 19.8%.
In general, the fourth, fifth and sixth types affect older and weaker people, and they were more likely to gain weight and have pre-existing conditions such as diabetes or lung disease compared to people of the first, second and third types.
The researchers developed a model that combines information on age, gender, body mass index, and pre-existing conditions, with symptoms collected only within 5 days of the onset of the disease.
And since most people who need breathing support come to the hospital about 13 days after their first symptoms appear, these eight additional days are an early warning about people who are likely to need more medical attention.
"These results have important implications for the care and monitoring of people most susceptible to severe cases of Covid-19," said Dr. Claire Steves of Kings College London.
"If you can predict these people on the fifth day, you have time to provide early support and interventions, such as monitoring oxygen levels and blood sugar and ensuring that they are properly hydrated (by getting fluid), through simple care that can be provided at home, preventing hospitalization, and saving Spirits. "
"Our study demonstrates the importance of monitoring symptoms over time to make our expectations about individual risks and outcomes more accurate," said lead researcher Dr. Carol Sodry of King's College London.
These results will have major implications for how the clinical management (method of treatment, medications, the need for oxygen, device placement, etc.) for Corona disease, and can help clinicians predict who are most at risk and who may need to seek hospital care.
