Exclamation Medical Alert

you have probably heard these days in the news about the outbreak of a new form of influenza in mexico. it's called the swine flu (grippe porcine).
This is really serious. Maybe much more serious than the avian flu.
we have all to be aware in case of a worldwide pandemic outbreak.


What Is an Influenza Pandemic?

A pandemic is a global disease outbreak. An influenza pandemic occurs when a new influenza A virus emerges for which there is little or no immunity in the human population, begins to cause serious illness and then spreads easily person-to-person worldwide.

Historically, the 20th century saw 3 pandemics of influenza:
  • 1918 influenza pandemic caused up to 50 million deaths worldwide
  • 1957 influenza pandemic caused 1-2 million deaths worldwide
  • 1968 influenza pandemic caused about 700,000 deaths worldwide

Characteristics and challenges of a pandemic
  1. Rapid Worldwide Spread
    • When a pandemic influenza virus emerges, its global spread is considered inevitable.
    • Preparedness activities should assume that the entire world population would be susceptible.
    • Countries might, through measures such as border closures and travel restrictions, delay arrival of the virus, but cannot stop it.
  2. Health Care Systems Overloaded
    • Most people have little or no immunity to a pandemic virus. Infection and illness rates soar. A substantial percentage of the world’s population will require some form of medical care.
    • Nations unlikely to have the staff, facilities, equipment and hospital beds needed to cope with large numbers of people who suddenly fall ill.
    • Death rates are high, largely determined by four factors: the number of people who become infected, the virulence of the virus, the underlying characteristics and vulnerability of affected populations and the effectiveness of preventive measures.
    • Past pandemics have spread globally in two and sometimes three waves.
  3. Medical Supplies Inadequate
    • The need for vaccine is likely to outstrip supply.
    • The need for antiviral drugs is also likely to be inadequate early in a pandemic.
    • A pandemic can create a shortage of hospital beds, ventilators and other supplies. Surge capacity at non-traditional sites such as schools may be created to cope with demand
    • Difficult decisions will need to be made regarding who gets antiviral drugs and vaccines.
  4. Economic and Social Disruption
    • Travel bans, closings of schools and businesses and cancellations of events could have major impact on communities and citizens.
    • Care for sick family members and fear of exposure can result in significant worker absenteeism.

U.S. Declares Public Health Emergency in Response to Swine Flu




SUNDAY, April 26 (HealthDay News) -- U.S. health officials declared a public health emergency Sunday in response to the swine flu outbreak, as the number of confirmed cases nationwide rose to 20. All 20 U.S. patients -- eight in New York, seven in California, two in Texas, two in Kansas and one in Ohio -- have recovered, Dr. Richard Besser, acting director of the U.S. Centers for Disease Control and Prevention, said at the news conference.
Meanwhile, in Mexico, believed to be the source of the outbreak, authorities continued to take dramatic steps over the weekend -- including suspending public gatherings -- to try to contain the swine flu outbreak that officials say has killed as many as 86 people, and sickened more than 1,400 others in that country.
In the United States, eight more cases of swine flu, all involving school students, were confirmed Sunday by New York City health officials, bringing the national total to 20.
And Canadian officials on Sunday reported four "very mild" cases of swine flu at a school in Nova Scotia. All four students were recovering, the AP reported.
Although all the reported cases in the United States have so far been mild, there are bound to be more severe cases.
The viruses found in the United States are resistant to two antiviral medications -- amantadine and rimantadine -- but are susceptible to the antivirals oseltamivir (Tamiflu) and zanamivir (Relenza).
steps were already being taken to devise a vaccine against this strain of swine flu, although the process takes time. But it takes months to produce a vaccine.
In response to the developments in North America, countries around the world planned quarantines, tightened rules on pork imports and tested airline passengers for fevers as global health officials tried Sunday to come up with uniform ways to battle the outbreak. Nations from New Zealand to France reported new suspected cases and some warned citizens against travel to North America, the AP said.
In Mexico, the government has ordered schools closed and all public events have been suspended for the time being, including more than 500 concerts and other gatherings in the city of 20 million residents. Even churches stood empty Sunday, the AP said.
While Mexico's flu season is usually over by now, health officials noticed a sizeable uptick in flu cases in recent weeks. According to a report published in The New York Times on Friday, World Health Organization experts said that most deaths among Mexican patients with swine flu have involved healthy young adults.
That could be worrisome, experts say. Seasonal flus usually strike hardest at infants and the elderly, but pandemic flus -- such as the 1918-19 Spanish flu, which killed an estimated 20 million to 40 million people worldwide -- often strike young, healthy people, the newspaper reported.
Swine flu is a respiratory disease of pigs caused by type A influenza. Swine flu does not normally infect humans. However, human infections do occur, usually after exposure to pigs. Symptoms resemble those of the regular flu, including sore throat, coughing and fever.

فيروس جديد قاتل لانفلونزا الخنازير

يظهر في المكسيك وقد ينتشر


مكسيكو سيتي (رويترز)

انتشرت في المكسيك سلالة قاتلة من انفلونزا الخنازير لم تعرف من قبل مما اسفر عن مقتل ما يصل الى 60 شخصا على الاقل واثارت مخاوف من انتشارها الى امريكا الشمالية.

وقالت منظمة الصحة العالمية انها قلقة مما وصفته بأنه 800 حالة "شبيهة بالانفلونزا" في المكسيك وايضا بشأن تفش مؤكد لسلالة جديدة من انفلونزا الخنازير في الولايات المتحدة. وافادت ان حوالي 60 شخصا لاقوا حتفهم في المكسيك.

وقالت حكومة المكسيك انها تأكدت من ان 16 شخصا على الاقل توفوا بسبب انفلونزا الخنازير في وسط البلاد وان 45 حالة وفاة اخرى ربما تكون نتجت عن المرض.

وأغلقت الحكومة المدارس امام ملايين التلاميذ في عاصمتها مترامية الاطراف والمنطقة المحيطة يوم الجمعة بعدما لاحظت السلطات عددا اكبر من المعتاد في الوفيات بأمراض شبيهة بالانفلونزا في الاسابيع القليلة الماضية.

وقال وزير الصحة خوسيه انجيل كوردوبا لشبكة تليفيزا "انه فيروس تحور من الخنازير ثم عند مرحلة ما نقل الى البشر."

وربط بين المرض في المكسيك والنوع الجديد من انفلونزا الخنازير الذي اصاب سبعة اشخاص في كاليفونيا وتكساس.

وقالت المراكز الامريكية للسيطرة على الامراض والوقاية منها ان الفيروس في الولايات المتحدة مزيج لم يعرف من قبل لفيروسات نمطية في الخنازير والطيور والبشر. وتعافى كل المرضى الامريكيين السبعة.

وعلى مستوى العالم تقتل الانفلونزا الموسمية ما بين 250 الفا و500 الف شخص في المتوسط سنويا.

وقال مسؤول في الادارة الامريكية ان البيت الابيض يتابع عن كثب الحالات الجديدة في الولايات المتحدة والمكسيك وان الرئيس باراك اوباما ابلغ بتطورات الوضع.

وحذرت الحكومة المكسيكية الناس من المصافحة او تبادل القبلات عند تحية بعضهم البعض او تقاسم الطعام او استخدام نفس الاكواب او السكاكين خشية انتقال عدوى الانفلونزا.

ومكسيكو سيتي من اكبر مدن العالم ويسكنها حوالي 20 مليون شخص. وبدت المدينة اهدأ من المعتاد صباح يوم الجمعة. وبدا الزحام المروري المعتاد اقل حدة في غياب حافلات المدارس وسيارات الاباء الذين يصحبون ابناءهم الى المدارس.

وانتظر كثير من الناس للدخول الى محطات المترو وكانوا يضعوا اقنعة واقية على وجوههم.

وقالت منظمة الصحة العالمية انها على اتصال يومي بالسلطات الامريكية والكندية والمكسيكية وانها نشطت مركز العمليات الصحية الاستراتيجية لديها وهو مركز تابع للمنظمة يختص بالتعامل مع الاحداث الصحية العامة الخطيرة.

Deux ou trois choses qu’il faut savoir sur la grippe porcine
Publié le 26/04/2009


Le 26 04 2009. Alors que le monde est, selon l’OMS, menacé par une pandémie de grippe porcine, nous proposons à nos lecteurs une courte mise au point sous forme de questions-réponses sur cette affection. Ce texte est basé principalement sur les informations mises en ligne sur le site des Centers for Diseases Control (CDC) d’Atlanta (1).

La grippe porcine est-elle une nouvelle maladie ?

Non. Il s’agit d’une affection atteignant le porc, décrite depuis des décennies. L’agent responsable de la grippe du porc « classique », un virus de type A H1N1, a été isolé pour la première fois en 1930. Quatre sous types principaux de virus A (classés en fonction de leurs protéines, hémaglutinines [H] et neuraminidase [N]) ont été isolés depuis chez le porc : H1N1 (le plus fréquent), mais aussi H1N2, H3N2 (mis en évidence en 1998) et H3N1. Le porc a la particularité de pouvoir être infecté par des virus provenant de différentes espèces : porc mais aussi homme ou oiseau. Ceci peut conduire à l’émergence de virus ayant un patrimoine génétique mixte comme cela, est semble-t-il, le cas dans l’épidémie actuelle.

Quelle est l’épidémiologie animale et quelles sont les manifestations chez le porc ?

La transmission de la maladie se fait d’animal à animal ou à partir d’objets souillés par le jetage. L’affection est hautement contagieuse dans l’unité d’élevage, la morbidité pouvant atteindre 100 %. Les CDC estiment que 25 % à 50 % des porcs américains ont déjà été infectés par un virus H1N1 et sont porteurs d’anticorps. Chez le porc, les signes sont essentiellement généraux (fièvre) et respiratoires (toux, jetage). La mortalité est généralement faible. On dispose en médecine vétérinaire de vaccins efficaces.

Que savait-t-on jusqu’ici sur la contamination humaine par des virus grippaux porcins ?

Des cas sporadiques de contamination animal-homme ont été décrits de longue date. Il s’agissait habituellement de sujets en contact étroit pour des raisons professionnelles avec des porcs malades. Cependant quelques observations de transmissions interhumaines ont déjà été décrites. L’épidémie humaine la plus importante semble être survenue au New Jersey en 1976 dans le camp d’entraînement de l’armée américaine de Fort Dix. Elle a concerné 200 personnes avec un cas mortel. Ni l’apparition ni la disparition du virus à Fort Dix n’ont été expliquées.
Pour faire face à cette épidémie, qui évoquait celle de la grippe espagnole de 1918, le président Gérald Ford décida en octobre 1976 de vacciner la totalité de la population des Etats-Unis. Ce programme fut interrompu après que 40 millions d’américains eussent été vaccinés dès le mois de décembre 1976 devant l’apparition de 500 cas de syndrome de Guillain-Barré (dont 30 mortels) chez les sujets vaccinés.
Le dernier décès par grippe porcine aux Etats-Unis date de 1988 et est survenu dans le Wisconsin. Avant l’épisode actuel, depuis 2005, 12 cas avaient été diagnostiqués aux Etats-Unis.
Les signes cliniques de la grippe porcine chez l’homme sont ceux d’une grippe saisonnière auxquels s’associent parfois diarrhées et vomissements. Les formes inapparentes après contamination interhumaine étaient jusqu’ici fréquentes puisque, par exemple dans le cas du Wisconsin de 1988, de nombreux sujets contacts asymptomatiques se sont révélés séropositifs pour ce virus. Il n’est pas possible aujourd’hui de connaître précisément le pourcentage de formes asymptomatiques avec le nouveau virus qui circule actuellement en Amérique du Nord.

Quand a débuté l’épidémie actuelle ?

L’épidémie actuelle à transmission interhumaine a touché primitivement le Mexique et le Sud des Etats-Unis. Selon les CDC, les premiers cas aux Etats-Unis ont été confirmés le 17 avril 2009 chez deux enfants vivant dans le sud de la Californie.

Quelles sont nos armes contre cette grippe porcine ?

Il semble que les vaccins efficaces contre la grippe saisonnière ne protégent pas contre cette grippe porcine et qu’un nouveau vaccin devra être développé.
D’après la très courte expérience des CDC basée sur les premiers cas survenus aux Etats-Unis depuis fin mars 2009 en Californie et au Texas, le virus serait résistant à l’amantadine et à la rimantadine mais sensible à l’oseltamivir (Tamiflu) et au zanamivir (Relenza). Ces deux produits sont donc recommandés (aujourd’hui) par les CDC en prévention comme en traitement.
