生蛇和水痘是由同一種病毒-帶狀疱疹病毒(Varicella zoster virus)引起的。
感染水痘或接種疫苗後,病毒會潛伏在人體的神經系統中。
當免疫系統低下時,病毒就有可能被激活。
它會沿著某一條神經線傳播, 並在皮膚上引起 紅疹 , 俗稱生蛇。
生蛇會傳染嗎?
你不會將帶狀皰疹 ”生蛇 ”傳染給別人。
但是,其他人可能會從帶狀皰疹中感染水痘。
如果你生蛇:
避免接觸免疫系統較弱的人、老年人和新生嬰兒 。
避免接觸孕婦。
保持患處遮蓋。
因為病毒是透過水皰中的液體傳播的。
生蛇建議不上班。
當水皰乾燥結痂後,你就不再具有傳染性了。
Shingles and chickenpox are caused by the same virus ,Varicella zoster virus.
After chickenpox infection or vaccine, the virus will stay dormant in the body's nervous system
When our immune system is low, the virus can be 'reactivated'
It will travel along a nerve and cause shingles on the skin.
Are shingles contagious ?
You cannot pass shingles to someone else
But
Someone can catch chickenpox from shingles
If you have shingles :
Avoid people with weak immune system, elderly, newborn
Avoid pregnant women
Keep it covered
As the virus is transmitted through the fluid in the blisters
Having shingles usually means staying off work
When blisters have dried and scabbed over you are no longer contagious.
