Humans have been battling viruses since before we had even evolved into our modern form, but we’re a long way from winning the fight against them. Here are a few of the worst killers.
Marburg virus
Scientists identified Marburg virus in 1967, when small outbreaks occurred among lab workers in Germany who were exposed to infected monkeys. The infected people develop high fevers and bleeding throughout the body. Marburg can be passed on from human to human via direct contact. The death rate is 80%in the 1998-2000 outbreak in Congo and in the 2005 outbreak in Angola.
Ebola virus
The first known Ebola outbreaks in humans struck Africa in Sudan and Congo in 1976. The natural host of Ebola is bats. The virus is spread through contact with infected people or animals. Symptoms include fever, bleeding and organ failure. The death rate is 50%to 70%.
Hantavirus
Hantavirus was first recognized as an infectious disease in the 1950s in Korea. But it first gained wide attention in the U. S. in 1993, when a healthy young man and his fiancee died within days of developing shortness of breath. Hantavirus was isolated from a deer mouse. More than 600 people in the U. S. are now infected and 36%have died. The virus doesn’t spread from human to human.
Mers-CoV virus
Mers-CoV virus had an outbreak in Asia, Saudi Arabia in 2012 and South Korea in 2015. The virus likely originated in bats. The disease infected camels before passing into humans and causes fever and shortness of breath. It has a death rate between 30%and 40%, making it the most deadly of the known coronavirus (冠状病毒) family. Mers-CoV spreads from one person to another.

How to avoid a boring conversation
What excuse should you use to avoid talking to people you don’t want to talk to? Here are tips and non-offensive ways to get out of unwanted conversations.
1. Go for a refill.
It is natural for anyone at a party to be excused to get a refill. 1. And once you excuse yourself, make a move fast before the person requests you to get a refill for him as well.
2. Pretend bad mood.
Cut off the conversation before it starts by saying something along the lines of “I’m not in a good mood. Can I talk to you later if you don’t mind? 2. Say it firmly so that people get the message loud and clear.
3. Ask your friend to save you.
3. Simply text your friend and ask him or her to come for apparently something important. You will be able to skip a boring chat with a seemingly reasonable excuse.
4. 4.
You are advised to look away from that person and don’t make eye contact, so that you can give powerful hints that you find the conversation extremely boring. 5. Be sure to tune in to the conversation every now and then so you don’t come across as rude.
A.Behave in an obviously careless way.
B.Just be sure that the person you are talking to does not offer to accompany you to do so.
C.Don’t act too polite in an attempt to draw sympathy.
D.Use body language to indicate boredom.
E.Your friend is bound to perform brilliantly in coping with the dull one.
F.Look elsewhere and pretend that something else has caught your attention.
G.Stuck in an unwanted conversation, how do you get out of it?
