This is a symptom that tells you that you are no longer contagious.
slap disease also known as Parvovirus B19 has given rise to much talk in recent months due to the massive spread of the infection, which has occurred almost all over the world and continues to spread as its symptoms allow spreads very quickly. Actually, Spanish Association of Pediatricians of Primary Health Care guarantees that parvovirus B19 It is highly contagious and is unique to humans, that is, in this case it cannot be transmitted from animals to humans and vice versa. However, this is not a cause for concern, since It’s usually not serious. What happens is that their symptoms incubate for several days, and that’s when the infection rate is highest.
“Heat and sun make symptoms worse.”
A disease characterized bright red rash on the skin, This lasts about a week and at the moment there is no vaccine to cure this disease. According to pediatrician Lucia Galan Bertrand, better known in the media as Lucia, my pediatrician: “It is contagious during the incubation period, which usually lasts one to three weeks.” During this period, we usually do not notice their presence until the first spots appear, starting from the cheek. Therefore, in common parlance it is called slap disease and spreads throughout the body. But, Once the rash appears, which is the most characteristic symptom of this viral disease, it means you are no longer contagious.
Should I isolate if I am infected?
slap disease It is easy to detect without the need for any laboratory testing. On the other hand, while it is true that this disease is more common in winter and spring, environmental heat and sun exposure worsen its symptoms. In this sense, some complications may arise, for example, sometimes the joints of the wrists, knees and ankles become inflamed, and in other cases it leads to anemia.
On the other hand, although it is a highly contagious disease, isolation is not necessary. In this sense Hospital Sant Joan de Déu in Barcelona clarifies on the portal Infosalus“Isolate the person who has a rash characteristic of this disease does not prevent infection because, as a rule, when the rash appears, the person is no longer contagious. there is little good hygiene habitsWashing your hands especially often is always a good idea as it can help prevent the spread of many infections.”
“An exanthema is a generalized skin rash that appears suddenly and unexpectedly because it is associated with viral or bacterial infectious diseases.”
When infected, the disease begins with catarrhal phenomena, A dark red rash then appears on the skin starting from the cheeks, giving the appearance of being “slapped in the face.” The disease progresses and spreads throughout the body, but the spots appear lighter. “Over time, the spots in the central part lighten, which gives the rash a “lacey” appearance,” they note from the Sant Joan de Déu hospital in Barcelona.
Difference between exanthema and erythema
When a red, rash-like rash appears, pediatricians advise applying pressure with your fingers. If, when pressed, the spots disappear for a while and reappear when released, we are faced with erythema.. In this case, redness of the skin is caused by dilation of the capillaries of the dermis, which increases blood flow to the affected area. This leads to the appearance of red spots on them, the appearance of which can be associated with many factors, either infections, allergic reactions, sun exposure, physical pressureIn particular.
From my side, exanthema This is a generalized skin rash, appears suddenly and without expecting it, since it is connected with viral or bacterial infectious diseases. They appear in the same way as erythema, that is, through red spots on the skin, but with the difference that the rashes can be of different types, such as papules, vesicles, spots, etc., all of them are of different sizes. and do not disappear when you press the skin with your fingers. The rash is a viral infection, e.g. measles, rubella, chickenpox, external exanthema or roseola, and some bacterial infections. whose rashes may or may not sometimes be itchy.
