Scientists have identified six primary forms of the disease caused by the coronavirus, Sky News reports, citing a study by king’s College London.
Experts analyzed data on symptoms that were observed in 1,600 patients in the US and UK. It turned out that the presence of specific clinical manifestations of the disease can indicate the severity of its course in the future. As a result, six different groups were identified according to the indicators of disease development.
Scientists described the first three forms as relatively light since, in such cases, only one and a half to 4.4% of patients needed respiratory support. Symptoms of the primary two “flu-like” forms include headache, cough, sore throat, and possible loss of sense of smell. In the first form, the patient may also experience muscle pain and chest pain. In the second form, the patient has an elevated temperature, hoarseness, and loss of appetite. In the third, “gastrointestinal” form, the coronavirus manifests itself mainly in the form of diarrhea and loss of appetite.
Scientists define the following forms as severe. The fourth causes constant malaise, fatigue, fever, headache and chest pain, loss of smell, coughing, and hoarseness. The fifth duplicate the symptoms of the previous one, adding confusion, loss of appetite, sore throat, and muscle pain.
The most severe, sixth, the form collects many symptoms, including headache, loss of smell and appetite, cough, fever, hoarseness, sore throat and chest, fatigue, confusion, muscle pain, shortness of breath, diarrhea, and abdominal pain.
It is noted that more than half of patients with the sixth type of disease need to be hospitalized, and only 16 percent of those with the first form is admitted to the hospital. Experts say that the detection of kinds of coronavirus will be a breakthrough in the fight against the epidemic and will help determine the risks of complications in patients.
