Contagiousness of MERS

The recent outbreak of MERS - Middle East respiratory syndrome virus - has infected at least 36 people in South Korea.  As a result, the outbreak has been a source of concern for epidemiologists around the world.  Efforts to quarantine people and camels have followed in an attempt to squash the outbreak.

Perhaps surprisingly, however, the MERS virus is not highly contagious; previous studies have found that its R0 is 2-3, meaning that the average infected person only infects two to three other people.  In fact, MERS is thought to be spread primarily zoonotically (from camels to humans).

It is important to note that while the MERS virus is not highly contagious, it is still important to monitor the outbreak and prevent it from growing any larger.  One issue commonly found in reports on the contagiousness of viruses is that there is an implication that less contagious viruses cannot manifest into epidemics and that they are less serious than highly contagious viruses.  However, with HIV - a virus that is relatively low in contagion (e.g. exposure to the virus via an infected needlestick seldom leads to infection) - we see that it can still lead to a deadly epidemic.  More recently, Ebola, a virus with an R0 if 1.5-2.5 manifested itself into the huge Ebola outbreak in West Africa.

Thus, articles reporting on the contagiousness of viruses should be taken just as a presentation of the facts, or as one of many indicators of the epidemic potential of a virus.

An amazing testimony on a spell caster who brought my wife back to me, My name is Eric Gomez, i lives in Los Angeles CA. and I'm happily married to a lovely and caring wife,with two kids, A very big problem occurred in my family seven months ago,between me and my wife so terrible that she took the case to court for a divorce she said that she never wanted to stay with me again,and that she did not love me anymore So she packed out of my house and made me and my children passed through severe pain. I tried all my possible means to get her back,after much begging,but all to no avail and she confirmed it that she has made her decision,and she never wanted to see me again. So on one evening,as i was coming back from work,i met an old friend of mine who asked of my wife So i explained every thing to her,so she told me that the only way i can get my wife back,is to visit a spell caster,because it has really worked for her too So i never believed in spell,but i had no other choice,than to follow her advice. Then she gave me the email address of the spell caster whom she visited.(Templeofloveandprosperity@gmail.com}, So the next morning,i sent a mail to the address she gave to me,and the spell caster assured me that i will get my wife back the next day what an amazing statement!! I never believed,so he spoke with me,and told me everything that i need to do. Then the next morning, So surprisingly, my wife who did not call me for the past seven {7}months,gave me a call to inform me that she was coming back So Amazing!! So that was how she came back that same day,with lots of love and joy,and she apologized for her mistake,and for the pain she caused me and my children. Then from that day,our relationship was now stronger than how it were before,by the help of a spell caster . So,you can visit his Web site to know more about him: http://africatemple.yolasite.com. if you have any problem contact Dr Frank Ojo, i give you 100% guarantee that he will help you. So thanks to Dr Frank Ojo for bringing back my wife,and brought great joy to my family once again.{Templeofloveandprosperity@gmail.com}, Thanks..

My name is Christabella, I am here to Share my testimony about a doctor who helped me remove a burden from my life. I was infected with HERPES SIMPLEX VIRUS in 2012, i went to many hospitals for cure but there was no solution, so I was thinking of how to get a solution out so that my body can be okay. One day I went to visit a friend and she asked why i was looking so sad i explained to her my problem, she told me that she can help me out, she introduced me to a doctor who uses herbal medication to cure HERPES SIMPLEX VIRUS and gave me his email, so i emailed him. He told me all the things I needed to do and also gave me instructions to take, which I followed properly. Before I knew what was happening after two weeks the HERPES SIMPLEX VIRUS that was in my body vanished . so if you are also heart broken and also need a help, you can also email him at: drkakuduwesthealingcenter@gmail.com OR dr.kakuduwesthealingtemple@outlook.com
