the epidemic continues to progress and strikes Ile-de-France


Threats are rising. Since January 2018, Europe has faced the worst mumps epidemic in 10 years: over 41,000 children in the continent (37 died) and adults over the last few months, twice as many as in 2017.

In Ile-de-France, the Regional Health Agency observed 56 measles cases in October, but a month earlier from 3 to 4 years, a significant increase, according to Aurélien Rousseau, Director General of the Agency in the French Bleu microphone, as each patient can infect 15-20 people.

The household will mainly be affected by Seine-Saint-Denis, and deaths have not yet been reported, while 11 have been hospitalized, mainly children 4 years of age and the vaccination is not up to date. No explanation is provided as to the origin of the outbreak of this epidemic, with the exception of the lack of vaccination coverage.

Immunization coverage is not optimal

In the Community, there is a minimum vaccination rate for protecting population groups and it protects those who can not be vaccinated (newborns, immune compromises …). This threshold is dependent on the stenosis of the disease.

In France, where almost 97% is covered by diphtheria immunization, the immunity threshold for the group has been exceeded and the entire national community is protected even in case of migrant infections. . Similarly, infectious Haemophilus influenzae infection in children, rubella or mumps has been almost eliminated in the country as the coverage level of these vaccines exceeds the immunity threshold for these three diseases.

On the other hand, the current immunization coverage for measles (79%) is still insufficient to ensure group immunity (group immunity threshold = 95%), and as a result, large-scale outbreaks of the epidemic occur. : more than 23,000 cases have been reported in France between 2008 and 2012, more than 1,500 serious pneumonia and more than 30 encephalitis with 10 deaths). It is unbearable and dangerous at a time when more than 41,000 measles are observed in Europe.

Two-stage vaccination schedule

Traditionally, the vaccination schedule consists of a dose of one MMR vaccine (measles, epidemic, feces) for 12 months and a second injection of 16 to 18 months. People who have never been vaccinated against measles can be exhausted. It consists of injections of two doses of vaccine for at least one month interval.

In the event of an epidemic, the vaccine can be given up to 72 hours after contact with a person who is suffering from measles to avoid the disease (vaccination is terminated). The vaccine is very well tolerated and has only pronounced contraindications. It's not the same with bait.

This is not a mild childhood illness

Burden is an infectious disease caused by a highly contagious virus, which in the past mainly affected young children aged 5-6 months. This is no longer the case: one third of the cases mentioned in France relate to people over 15 years of age. A patient can be contaminated up to 20. Burdens are 10 times more contagious than flu. It is easily transmitted from one person to the other by air, coughing, sneaking or contacting contaminated objects (toys, handkerchiefs …).

Frequently mistakenly believed to be benign, "measles is not only a childhood illness but also affects adolescents and young people and can lead to serious complications (pneumonia, encephalitis …) and sometimes even hospitalization" or death, the Occitanian Regional Health Agency recently explained.

23 000 cases in Ukraine

Ukraine is the hardest hit country, which has 23,000 cases in 6,000 months, followed by surveillance Serbia, Russia, Italy, Georgia, Greece or France. According to Santé Publique France, "the number of measles cases has increased significantly since November 2009 (France, editorial note). This situation is associated with insufficient provision of vaccination in infants (79% with two doses of vaccine 95% needed), children and young people."

More precisely In France, there were 2741 cases reported between November 6, 2017 and August 2018, of which 22% were hospitalized and three deaths since January. In short, contrary to popular belief, measles is neither eradicated nor a benign infantile disease. It also affects adults, can cause complications a lung or neurological problem or even a fatal outcome.

Bait around the world

Mass remains the leading cause of death for children with poor health, but WHO is a huge work. Between 2000 and 2005, more than 300 million children aged between nine months and 15 years were vaccinated or revaccinated. In 2015, nearly 77% of the world's population was vaccinated, resulting in a further decline in mortality: less than 345,000 deaths from 20 million people this year.

In 2005-2010, a measles eradication plan was set up in Europe. Elimination occurs when the epidemic – even small – does not take place for a year or longer. It is based on vaccination, so the mandatory vaccination logic in France from January 2018.
