What are the symptoms and dangers of smallpox virus?

The smallpox virus is a very ancient virus with a very high mortality rate. In ancient times, it was basically a terminal illness and people could only leave it to fate. However, with the continuous advancement of science and the rapid development of human medical capabilities, this malignant virus, smallpox, has long been eradicated by humans. But people cannot rest easy from now on. They must always bear in mind the dangers of smallpox and guard against its return, which has always posed a huge threat to people's lives. Most modern people are unfamiliar with smallpox. Let’s take a look at the symptoms and dangers of the smallpox virus. Those who are interested can find out more.

Smallpox virus is a highly contagious disease and the only infectious disease that has been eradicated by humans worldwide so far.

symptom:

Benign smallpox symptoms During the first week after infection, the virus remains quietly active in the body. The patient will not have any symptoms and there is no way to confirm it. Around the ninth day, the first signs of illness begin to appear: headache, fever, nausea, backache, and sometimes some cramps or confusion.

During this incubation period, some patients will also have nightmares that can last for three or four days. Patients will have scattered dark red spots on their face and all over their body. At the end of the incubation period, the patient's high fever subsides and he or she temporarily feels better. It is also at this time that the smallpox virus begins to produce its characteristic red rash on the patient's body. Typically, these flat, light red spots first appear on the face and quickly spread to the arms, chest, back, and finally legs.

harm:

Once people are infected, they can only leave it to fate. Symptoms of fulminant smallpox Patients with fulminant infection usually die within 3 to 5 days, usually due to uncontrolled toxemia or massive bleeding. In a major hemorrhage, a large amount of blood flows into the skin, throat, lungs, intestines, or uterus. Such patients do not have typical papules or blister-like protrusions, but only common red or purple marks, petechiae or measles-like erythema. These symptoms may also occur when the human body suffers from a serious infection or when the blood coagulation function is severely damaged. In other cases of virulent infection, when the smallpox virus is severely damaged in the tissue layers or deep layers of the skin, it causes widespread destruction, and the patient dies within 10 to 14 days after the onset of symptoms, with pustules all over the body, sometimes fused. The lesions in patients with benign infections are limited to the epidermis, which makes them less likely to cause secondary bacterial infections.
