Monkeypox: symptoms, how it is spread and keys to differentiate it from another disease

But "in many cases,

Tonsillitis assume that it is due to close contact with infected areas.

The lesions included in the article are also observed in the weekly 'report' of the infection provided by Health: of the cases in which there is clinical information,

All this draws

"We must take into account the new forms of presentation to decide if the current isolations are sufficient or not," says the dermatologist about one of the critical points when it comes to cutting infections.

Again, another work emphasizes the transmission of the virus: "The work we have done

as the dominant factor in the transmission of monkeypox", Tarin points out.

Last week it was the Spanish Association of Dermatology who, through a study in the

, highlighted this fact: fewer skin lesions, but in areas of sexual contact.

Despite the fact that both works bring together small groups of patients, no more than 200, they do suggest that the transmission of the virus maintains a specific pattern far from what was considered until now: an animal-to-human contagion.

Now, it occurs between humans during sexual intercourse mostly.

"

This influences the measures that must be taken," clarifies the Madrid dermatologist.

One of the points in which Mitjà considers that it is necessary to improve, as they also conclude in the analysis, is in detection.

"In units specializing in sexual health or sexually transmitted infections, good clinical management is done, but it varies from one clinic to another.

."

This is because monkeypox appears in atypical forms and this requires physicians to have a high index of suspicion for the disease, which can be achieved not only with current protocols but also with epidemiological interviews.

This is so because the work

"And this is important, because

And we need it to be known beyond the weight of the stigma. In this time, we have seen many patients and the emotional issue means that many patients do not consult, do not go to the centres... This is an error that we must correct", emphasizes Turin.

Prophylactic use of virus vaccines

They were not the object of study of his analysis, as Mitjà recalls, but

Turín comments.

"We have seen that its use can be more useful in pre-exposure."

The dermatologist explains that through a case in his hospital they have confirmed that "

".

The partner of an infected patient was given the vaccine "as a result of close contact in the first few days, but we do not know if he later developed a mild infection due to the vaccine or because it was going to happen that way for other reasons."

In our country there are

Madrid and Catalonia have already put more than a thousand each, and little by little the rest are added.

Most administer it prophylactically in populations at high risk of contagion.
