Learn the full story about ebola


I’ve written about ebola before and you need not fear if you’re outside West Africa. Ebola, also called Ebola Virus Disease, generated by the Ebola Zaire strain, is a virus that can be transmitted only via direct contact. So, if you’re in the same room with someone that is ill of ebola, then don’t touch him and do not let any of his fluids touch you: vomit, blood, spit. Survival rates are below 30%.

The disease has been discovered first time in the 70ties in animals and has since infected small pockets of humans, but the outbreak from this year is the biggest one. Ebola is able to spread in West Africa due to the lack of sanitation, burial practices that put relatives of the dead in direct contact with the dead (washing for example), too few medical staff.

Ebola has killed until now 10 000 people in almost the entire year. Comparatively, malaria, diarrhea, lack of food and water have killed a couple of million people in Africa this year. Ebola is a vicious disease, but nowhere as effective in killing people as the other situations.

All you need to know about Ebola în 1 minute


The guys at Vox created a short video about Ebola and it puts a perspective on what it is and its actual effects. Ebola’s mortality rate sis 70%, there is no cure for it, 4500 are dead this year only because of it, in 2014 died three times as more people as have dies since 1970.

Also, since it is not airborne you can contract Ebola only with direct contact with the bodily fluids of a person showing the symptoms.

What you need to know is that annually more than 1 million people die of AIDS in Africa and 500k and 600 k people die of malaria and diarrhea each year. Compared to those, Ebola is small baby, albeit a dangerous one.

Diseases: bubonic plague, ebola, herpes + where we donate vs what kills us


Right at the middle of the week I hit you with an article about diseases. Come on, you gotta love ’em. They show our nature and they are kind to the population by killing the weak ones. Kidding. diseases are bad and we must take every possible step in destroying it. Fortunately, vaccines and a cleaner world we live in have pretty much keps diseases at bay.

For example, the bubonic plague still exists today in certain places of the world, but we are safe from it because we keep our houses clean, we clean our selves a lot, use antibiotics and have a way better medical system now. Also, because so many have died in the past, only the strongest remained to send out stronger genes to us.

Analyzing bubonic plague will help us create better cures that will cover a hole range of diseases that work in similar ways to it.

What about Ebola? Well, fighting it with technology will ensure that in the future we will overcome this disease too. Since we now have containment procedures, hospital that can quarantine ill people and tech that can track the disease in airports, we can now be safer:

Now, are you ready to have your mind blown by Vsauce 2 in Mind Blow #86? Well, find out that most of us have herpes, but it won’t affect most of us if we have a strong immune system. You, yes you, may have hespes:

Another thing to think about: where we send our donations money and what actually kills more people. The disparity is incredible. We give money for breast cancer, prostate cancer, heart disease and ALS, but the top #4 killers are, in fact: heart disease, pulmonary diseases, diabetes and then breast cancer. the order is… out of order.

Good to know that people donate money, but they better be donating where it’s most needed:

Learn all there is to know about Ebola from Scishow


Hank Green, from SciShow, explains what Ebola is, and where is it coming from. It is not contagious as, let’s say, the flu, but it is nonetheless a deadly disease that can kill 90% of the infected victims. Ebola is transmitted to other hosts via direct contact (of your mouth, eyes, or open wound) with bodily fluids from the patients: vomit, urine, fecal matter, semen, blood. It transmits much like Hepatitis B.

So, in case you get near a guy with Ebola make sure to not touch anything they touched and stand at a certain distance. You’ll be safe. I wrote about Ebola before in this blog post. Even if it so deadly, if the patients are quarantined, the there is no such a big deal.

Those two Ebola patients in US are NOT a threat. Ebola does not spread through air!

Ebola is a disease caused by an RNA virus called Zaire ebolavirus is one of the five such viruses. The one from Phillipines does not kill people. The gruesome fact about Ebola is that is leads to organ failure and a lot of bloodshed: you expel blood through your mouth, eyes, ears.

It has been calculated that 90% of the Ebola virus patients die. With proper care 57% of the patients die. Proper care = allowing the blood to clot, giving blood perfusions, hydrating the patient.

Now comes that hard question: is it contagious? Not nearly as bad as the influenza or tuberculosis. More people dies from AIDS, measles or yellow fever than from Ebola.

Ebola spreads int he same way HIV spreads: through bodily fluids. That mean that it spreads through blood, saliva, semen, urine, poop, vomit or through un-sterilized syringes. If any of these fluids comes in contact with the mucus membranes of the mouth or eye or with an open cut, then you get infected.

So, Ebola is not that contagious, but it is deadly. People in Africa get infected when they come in contact with the bodies of dead people or when they prepare meat from monkeys infected with Ebola. If you prepare such infected meat and cut yourself, then you get infected.

Ebola outbreak in West Africa


Vice News Reports that more than 357 people have already died of ebola in West Africa‘s countries like Sierra Leone, Guinea, Liberia and Cote d’Ivoire. As it is summer time now in the Northern Hemisphere many would like to go to Africa. Guys, first ask at your embassies about the ebola outbreak that is now in West Africa.

How do you die from ebola? The virus simply causes you to bleed internally and then externally through mouth, eyes or even anus. That is not something to play with and there is not cure for that. 90% death rate.

How do people get infected with ebola? They eat bushmeat, especially monkeys which carry the ebola virus, and some of these people cut themselves during cooking the bushmeat. This way the virus gets inside their bodies, through the wounds.

Transmission? Human-to-human transmission occurs via direct contact with blood or bodily fluids from an infected person (including embalming of an infected dead person) or by contact with contaminated medical equipment such as needles. Good to know that it does not spread via air, or we’d been toast by now as many people visit those places each year. Don’t touch people or equipment touched by people with ebola.

Usually, the infected meat, if it is cooked,can be eaten without getting ill of ebola.

Make sure to be careful if you go into West Africa or Sub-Saharan regions.
