What is the reason for the redness in the palms of the hands of pregnant women?

Patients with novel coronavirus pneumonia may have fever in the palms of their hands. However, this symptom is not the main sign of the patient and cannot be used as a diagnostic condition. In addition, fever in the palms of the hands can also be present in people with heat evidence in the liver and heart meridians. However, when a patient has a history of relevant exposure and neoplastic pneumonia is suspected, prompt medical attention for nucleic acid testing can be sought.
