Smallpox: What are the isolation rules if you have been infected, suspected of a case or contact?


Smallpox continues to spread slowly in several countries around the world, including France, where 7 cases have been confirmed. If the scientific authorities want to be reassuring, Public Health France, on the other hand, has announced measures to limit the spread as much as possible.

Although several cases of ‘chickenpox’ virus, which is responsible for monkeypox, have been identified, it is the unusual nature of the spread that currently fascinates health authorities because “they are not imported from countries that usually report cases,” Public Health France said. Wednesday, May 25.

Atypical situation

“To date, these cases have occurred in Europe mainly, but not only, in men who have had sex with men who were not directly related to people returning from endemic areas,” the French health authorities added.

In an effort to limit the spread of the virus, described in this situation as “atypical,” SPF established an isolation protocol for infected persons, probable cases or suspicious cases, add that suspicious cases must be reported to the ADR and that all confirmed or probable cases in France must be subject to mandatory reporting.

Depending on the case, Public Health France recommends its own isolation. We carry out an inventory of recommendations issued by the National Agency.

For infected people

People who have been contaminated and who test positive must complete a mandatory statement and an investigation will be carried out to determine the origin of the contamination.

As regards the behavior to be observed, “Confirmed cases must be isolated at home for 3 weeks from the date of onset of symptoms, unless their clinical condition requires hospitalization. Loss of work or permission to work full time can be issued to them by their attending physician, “says SPF.

They must also isolate themselves from the people in their homes, wear a mask, do not have physical contact with other people, and “do not share their clothes, linen, and bedding or dishes with others.”

For “probable cases”

Public Health France defines probable cases as persons who have “An evocative blister eruption FEM2, whether or not preceded by a fever sensed or measured above 38 ° C “ and who 3 weeks before the onset of these symptoms was either in high-risk contact with an infected person, returned from an endemic area, or had sex with men or multiple or anonymous sex (regardless of direction).

Isolation is also required in these individuals for 3 weeks from the onset of clinical symptoms. and interruptions or permits to work remotely may be issued under the same conditions as above.

Probable cases will also need to list vulnerable contact cases (see below) in the ADR in order for the contact to be traced.

For “suspicious cases”

Unlike a “probable case”, a person considered a “suspicious case” shows many symptoms, but would not be in situations of probable exposure to the above disease.

Suspicious cases should be tested and isolated at home while awaiting the outcome.

For “contact cases”

People called contact cases are those who have had close contact with an infected person or a probable case. “unprotected direct physical contact”, SPF means any contact with damaged skin, body fluids, sexual intercourse, medical caresharing of toilet utensils or contact with textiles or dirty dishes or unprotected contact within two meters for three hours.

In these people, SPF does not recommend isolation in the absence of symptoms. On the other hand, vaccination will be offered“Ideally within 4 days after the risk contact and no later than 14 days later” according to Public Health France.

They must also monitor their temperature, which may occur before rashes, and mark the onset of infection.
