Recent news about H5N1 avian flu and H1N1 swine flu

Recently, there are news about a death from H5N1 flu in Alberta, Canada. This has caused an influx of patients seeking the flu vaccine at the pharmacy. It is important to clarify that the seasonal flu vaccine does not protect against the H5N1 avian flu virus, however, it is still effective in protecting you from the most common flu virus in Canada, such as the H1N1 flu virus. 

What is the H5N1 avian flu? 
H5N1 is an avian flu virus that is commonly found in poultry across Asia and the Middle East. Most patients infected with the H5N1 virus have come in close contact with sick or dead and infected poultry. The majority of human H5N1 cases have been linked to home slaughtering of diseased poultry before cooking. Since the virus is sensitive to heat, you cannot contract H5N1 from properly cooked eggs and chicken. Although it is difficult for the H5N1 virus to transmit from person to person, you can still contract the virus from being in contact with an infected H5N1 patient.

What is the difference between H5N1 and H1N1? 
Human cases of H5N1 are rare, especially in Canada. However, once a patient is infected with the H5N1 virus, the mortality rate is 60%. It is important to note that the H1N1 flu virus is much more common in Canada. Also, H1N1 can be commonly transmitted from person to person. It is still important to get vaccinated in order to protect yourself from the most common types of flu virus in Canada.  

Custom Care Pharmacy is still providing flu vaccination, no appointment necessary. If you haven't received vaccination this season, it is not too late to get vaccinated.  

關於H5N1病毒和H1N1病毒的新聞

最近, 有新聞關於H5N1病毒導致的死亡病例。正因為如此有很多人一下子來到藥房尋求流感疫苗。其實,許多人並不清楚流感疫苗可以預防哪種類型的流感病毒
2013-2014年的流感疫苗可保護免受三種流感病毒:H3N2H1N1B型流感病毒。所以,季節性流感疫苗是不可以預防H5N1病毒的感染。然而,注射季節性流感疫苗仍然是重要的。因為它可以預防在加拿大最常見類型的流感病毒。

什麼是H5N1病毒?

H5N1是一種高致病性禽流感病毒,常見于亞洲和中東部分地區的家禽。然而

人類感染這種病毒的病例是非常罕見的,它是很難從人傳播給人,但是被感

染的人的死亡率大約是60%。多數感染H5N1病毒的患者曾與病禽或死禽密切接觸過。

人類也可能通過長期暴露於H5N1病毒的環境,如活家禽市場,在國外旅行,

或與感染H5N1禽流感患者接觸後感染病毒。但是, H5N1病毒從人到人的接

觸傳染是非常罕見的。


因為H5N1型病毒對熱敏感,你是不會從正當處理及煮熟的家禽和蛋類中感染

到H5N1病毒的。據世界衛生組織調查,大多數人感染H5N1病例都與家禽屠宰

和病禽在烹調前的處理有關。


關於H1N1流感的事實:

•因為每年季節性流感傳播不同類型的病毒,所以每年要生產一種新的流感

疫苗以預防 來年最常見的三種流感病毒株。

•H1N1病毒仍然是本季流感主要的 病毒亞型。

•嚴重的導致住院觀察的流感病例往往是與感染了H1N1病毒有關。

•據報導20-64歲之間的成年人流感病例比例更高。

•感染了H1N1病毒的症狀類似于普通季節性流感的症狀。包括咳嗽,發熱,

寒戰,食慾不振,咽喉痛,流鼻涕,頭痛和全身酸痛,有些感染了 H1N1病

毒的病患還可能會出現噁心,嘔吐和腹瀉。

•H1N1病毒具有高度傳染性,可以從人迅速蔓延到人。即使你往年注射過含

有H1N1病毒的流感疫苗,也不能確保今年仍然受到保護。一般來說,接受

流感疫苗一年后人對流感的免疫力會減弱,並需重新注射來強化免疫力以獲

最佳的保護。
