Flu 2022 map Brittany under surveillance symptoms

SEASONAL FLU EPIDEMIC. The flu epidemic is gaining ground in France in this month of November 2022. Especially Brittany, which is entering the pre-epidemic phase. We must protect ourselves because this year, the flu could be more deadly. Symptoms, duration, contagion time: know everything.

[Mis à jour le 22 novembre 2022 à 14h50] In this month of November 2022, the flu indicators are currently at their basic levelbut the consultations in town and at the visits to the hospital are up in the under 15sreports the latest bulletin from Public Health France. The Brittany is in the pre-epidemic phase (orange on the map). The threat of a deadlier seasonal flu than in previous years (she was absent during the winter of 2020-2021 but she reappeared the following season in the first quarter of 2022), and the risk of excess mortality linked to viral coinfections, are to be feared, reports the Academy of Medicine on 9 November. Must therefore be careful and again respect barrier gestures. “We haven’t had a major flu epidemic for two years and so our overall immunity to the flu has probably waned“, warned Professor Brigitte Autran, president of Covars, on October 4 on RMCbeforeencourage “hugely” vaccination against the flu, as much as against the Covid. Especially the elderly, frail and pregnant women. Since November 15, 2022, vaccination is open to all. Note that there are approx. 2 to 6 million cases of flu each year in France. What are the flu symptoms ? The incubation period? The disease duration ? Is she contagious ? What are the treatments (natural or medicinal) to heal quickly? When to get vaccinated?

Epidemic 2022: how many cases of flu at the moment?

The flu epidemic continues to gain ground in France, especially in children under 15. According to Public Health France, as of November 21, 2022, all the regions are in green on the map, in other words, at their basic level. Only Brittany is in the pre-epidemic phase (orange on the map). Mayotte, Réunion and Martinique are in the epidemic phase (red on the map). The incidence rate of consultations for an influenza-like illness is 71 per 100,000 inhabitants (Sentinels Network), an increase compared to the previous week. This trend was observed in all age groups but was more marked among those under 15, in particular in children under 5 years old. Since the start of monitoring, 7 serious cases admitted to intensive care.

Definition: what is a flu?

The flu is a acute respiratory infectiondue to a influenza virus, while an influenza-like illness can be caused by many other respiratory viruses like rhinovirus, respiratory syncytial virus, etc. Influenza viruses are mainly divided into two types: A and Bdividing themselves into two subtypes (A(H3N2) and A(H1N1) pdm09) or lineages (B/Victoria and B/Yamagata). Type A influenza viruses circulate in many animal species (ducks, chickens, pigs, horses, seals, etc.). Influenza viruses from B-type circulate mainly in humans. Viruses A and B cause seasonal epidemics in humans, but only type A viruses have been responsible for pandemics to date, points out Public Health France. In autumn 2022, the A(H3N2) virus circulates mainly in France.

What are typical flu symptoms?

Each year, flu epidemics can affect all age groups, but the most vulnerable people are the children under two years old, adults over 65 and people with certain chronic diseases. Early symptoms of the flu include:

  • great fatigue,
  • chills even when you are not cold,
  • a dry, painful cough
  • then comes the fever which can rise to more than 39°c,
  • aches,
  • headaches…

In all cases, in case of sudden aggravation or without improvement of the state 72 hours after the first symptomsit is essential see a doctor.

When to get the flu shot?

Vaccination is recommended for people at risk and healthcare professionals, and is the best way to protect against influenza and its complications. It’s necessary allow approximately 15 days between vaccination and the time when the body is protected against the flu. No need to wait for the first cold weather or the start of the epidemic to get vaccinated. The last vaccination campaign ended on February 28, 2022.

How long does a flu last?

A hard flu between 3 and 7 days (5 days on average).

What is the incubation time for the flu?

The incubation time (the time between the moment of illness and the appearance of symptoms) generally lasts between 24 and 48 hours, but it can be extended to 72 hoursrecalls Dr. Parneix. However, the patient is contagious, even before the appearance of symptoms and this, during an average period of 6 days.

Is the flu contagious?

The flu is a contagious disease. The patient can transmit it “even before the onset of symptoms and during an average period of 6 days“ recalls our interlocutor.

To be infected with the flu virus, you must be in contact with someone who already has the flu. Contamination can occur in three ways:

  • The first by airway : a sick person projects droplets of saliva into the air, when talking, coughing or sneezing. Millions of viruses are then found in the air, ready to be inhaled and contaminate you.
  • The second, by close direct contact : a sick person shakes your hand or kisses you.
  • Finally, contamination can occur through the contact with touched objects by a sick person, for example a doorknob or a telephone.
  • Cough at the bend of the elbow and cover the nose when sneezing,
  • Wash your hands with soap regularly throughout the day, especially after blowing your nose, coughing or sneezing.
  • Blow your nose in a tissue and then throw it in the trash, ideally closed with a lid,
  • Carry a surgical mask if you are sick and you have to go to a closed and public place, this prevents contaminating others.
  • the hydroalcoholic gel is also practical, but in the long term it can dry out the hands.
  • Finally, remember to air the rooms regularly, several times a day: you will thus eliminate stagnant viruses in the air, through sneezing and breathing.

Treatment: how to cure a flu?

In case of flu-like symptoms:

  • Consult the doctor quickly. He or she will be able to make the diagnosis and prescribe the most appropriate medications.
  • Take some paracetamol to reduce fever, aches and pains.
  • The vitamin C is also sometimes recommended to combat fatigue. Similarly, certain foods are particularly recommended to better combat fatigue.
  • If necessary, you can complete with a nasal decongestant and one cough suppressant for dry and stubborn coughs.
  • Finally, it is necessary drink plenty and rest.
NO ANTIBIOTICS!

“The flu is caused by a virus and antibiotics are totally ineffective in treating viral illnesses, moreover they could deteriorate the good bacteria which the body needs to defend itself from illness” recalls Dr. Pierre Parneix.

What are the natural treatments to relieve the flu?

Garlic, lemon, honey, thyme… Several natural solutions can help boost the immune defenses in the prevention or treatment of the flu.

Figures: what is the assessment of the last epidemic (2021-2022)?

According to the epidemiological update published in October 2022 by Santé Publique France, influenza viruses began to circulate in December 2021. The epidemic started in March, peaked nationally in early April and ended in late April, that is 9 weeks of epidemic. No other influenza epidemic had reached its peak as late over the period 2009-2022. A co-circulation of A(H3N2) and A(H1N1) viruses was observed, with a diversity of viral strains detected. Its impact was moderate in the general population, but important in children under 15.

What should I do if my child catches the flu?

To prevent your child from contracting the flu virus, it is important to teach him how to blow his nose in a single-use tissue, to cover his nose to his mouth when sneezing or coughing. In any case, consult your pediatrician so that he can examine him and administer, depending on the case, the most appropriate treatment, especially against fever.

To limit the seasonal flu epidemic, it is essential to adopt simple preventive measures on a daily basis aimed at limiting the circulation of the flu virus, particularly in communities and on public transport where it is easily transmitted. For those around people with the flu, it is recommended to respect these few hygiene rules:

  • Wash your hands regularly and systematically after each outing and each contact with the sick person.
  • Avoid close contact with the person with the flu and in particular if you yourself are vulnerable or “at risk” (pregnant women, seniors, people suffering from a chronic illness or immunocompromised, young children, etc.)
  • Wash yourself regularly hands with soap and water, or if you cannot do otherwise, with a hydro-alcoholic solution, especially after any contact with the patient and after each return home.
  • Do not share objects such as glasses, cutlery and of course toothbrushes.
  • Ventilate its interior every day between 10 and 15 minutes to renew the air and prevent the proliferation of viruses.
  • Clean germ nests such as door handles, remote controls, phone screens…
