【血和新冠狀肺炎】血型A感染風險高！蚊傳武漢肺炎？天然驅蚊法！
經過數月新冠狀病毒肺炎 (covid-19) 的打擊，大家可能都開始習慣 勤洗手、保持社交距離、口罩生活… 了，繼續加油~
血型與新冠狀肺炎
covid-19 血型統計
雖然新冠狀病毒仍然新，但已有不少研究報告被發表，當中一份研究報告以「血型」與covid-19病毒感染比率作統計。
報告中指出武漢居民中「血型A」人士感染風險較高！
居民中A型血人口比例只有 31%，但 A型血居民患上新冠狀肺炎比率逹 38%。
報告同時顯示了，「血型O」的武漢居民感染率低！而O型血人口平均比例為 34%，但只有 25% 的人患病。
那麼，A 型血朋友應擔心嗎？
❝不用擔心！
免疫學家認為感染冠狀病毒肺炎有很多不同風險和因素需要考慮，所以血型並不是最重大的影響！
我們繼續注意手部清潔、戴口罩、保持社交距離和如果有上呼吸道感染自我隔離，減低傳播風險 預防新冠狀病毒 ，互相保護！
蚊傳播武漢肺炎嗎？
雨季將至，蚊子滋生可能又會是另一煩擾問題，既然在血液中能檢驗出新冠狀病毒，那麼被蚊叮會否傳染武漢肺炎？
專家指，新冠狀病毒 (covid-19 ) 主要經過飛沫傳播，並提醒我們不用過份擔心，蚊叮並不會傳染武漢肺炎。縱使牠不會傳播武肺，卻會傳播不同的嚴重疾病：
白紋伊蚊 Aedes
傳染：登革熱
庫蚊 Culex
傳染：日本腦炎
虐蚊 Anopheles
傳染：瘧疾
天然驅蚊方法
人體氣味、熱量、光線和濕度共同作用誘使蚊子向我們叮咬。不論你遇到以上哪種蚊子，都需要保護自己，然而，不一定使用DEET的化學驅蚊劑 (蚊怕水、蚊膏…)，因為 DEET 產品有可能引起環境或健康問題。
我們可選擇或自製天然的驅蚊劑，減低敏感或健康影響：
❯ 檸檬桉樹油 +
檸檬桉樹油是常被使用的天然驅蚊劑成分之一，而且安全。
DIY：1份檸檬桉樹油，10份向日葵油或金縷梅混合，安全噴在身上。但佛羅里達州大學研究員提醒，勿使用在3歲以下小童身上。
❯ 薰衣草 +
碎的薰衣草產生的香味和油脂能有效驅除蚊子，另外，薰衣草精油同樣能有效驅蚊。研究顯示，薰衣草具止痛、抗真菌的功能，它能鎮靜和舒緩皮膚。
DIY：將薰衣草壓碎，然後把薰衣草油塗沫在腳踝和手臂位置驅蚊。
DIY：將精油滴在乾淨的布上，直接擦在皮膚驅蚊。
❯ 肉桂油 +
肉桂油也是驅蚊劑的有效成分，最有效驅除「亞洲虎蚊」。
DIY：製作 1% 稀釋溶液。將 4 盎司(oz)水 混合肉桂油 24滴 (1/4 茶匙)。可將混合後的驅蚊劑噴在皮膚、衣服、或身旁裝飾物上。
❯ 百里香油 +
混合百里香油的天然噴劑有防蚊。
DIY：將 5 滴百里香油和 2 盎司(oz)水混合，製成防蚊噴霧。
❯ 薄荷油 +
薄荷能防蚊，效能可達 2-3小時。
研究顯示，薄荷在貓身上的防蚊功效是 DEET 的10 倍。
❯ 香茅 +
香茅油成分產品的驅蚊功效和 DEET 產品相似，不過香茅油會被迅速蒸發，所以選擇香茅驅蚊產品時應注意其配方和持久度。
注意：避免將未經稀釋精油直接塗在皮膚上！
