There are lot of diseases which can kill a person within few hours. In addition to the fact that the mortality rate ranges from 50% to 90%, it is also highly contagious.
Vaccines from the Ebola virus have not yet been invented. From the first symptoms of the disease to the fatal outcome in the form of a massive hemorrhage can pass from a few hours to a day.
Good news: the virus is transmitted not by airborne droplets , but only when you touch the bodily secretions of the diseased. Therefore, the infected almost immediately isolated. The bad news (they actually two): natural foci of the virus are in very poor countries , where there is a no developed health system. So, it is very difficult to detect the disease at once. The second bad news: people today are moving around the world. So quite a few hours , so that the disease spread to other continents.
For example , this is what happened to the SARS epidemic , which erupted simultaneously in Singapore and Canada. Fortunately , since these are countries with a developed health system , the disease was quickly stopped. What can not be said about Africa.
One of its fatal forms is myocardial infarction.
The blood moves upward, against gravity, because the pressure in the arteries and veins is different.
The heart has its own vessels, which feed the muscle. They are called coronary. If the lumen of the walls of the cardiac arteries is sclerosed, the arteries become narrower, coronary heart disease arises.
The disease leads to a thrombosis of the heart vessels, and the nutrition of cells ceases. Cells can not live without food and oxygen for a long time, and if after 30 minutes the nutrition and delivery of oxygen do not normalize, cell death occurs.
To reduce the risk of heart attack, it is necessary after 30 years to regularly be examined by a cardiologist for heart and vascular health, and also to quit smoking. It is important, that you have had enough physical activity – it trains your blood vessels and makes them more elastic, so that they are less prone to blockage by atherosclerotic plaques. Do not forget to also monitor the pressure!
It all started with gophers. In 1910 a group of scientists from the California Anti-Plague Station drew attention to strange abscesses. At first, they thought , that they were dealing with the bubonic plague ( also opening a very unpleasant). But the bubonic plague microbe could not be detected ,but found a new , previously not known – Bacterium tularensis. Later , in honor of the scientist ,who worked with him , he was called Francisella tularensis.
The incubation period sometimes lasts only a few hours , although sometimes it lasts up to 21 days. The disease begins with a sharp rise in temperature , severe headache , dizziness , muscle pain and conjunctiva in the first days of illness. The forms of the disease are many , and it develops quite quickly.
Although tularemia is treated with antibiotics , it is better for her not to become infected. Infection is transmitted to a person most often by direct contact with infected animals. Tularemia bacillus carriers: rabbits , rabbits , water rats , voles. Less often the infection can be picked up through contaminated food and water. So even if you see a clearing very cute rabbit , do not approach him , and do not hang in those places , where many rats ( landfill , in big cities – the garbage in the backyard of the restaurants or supermarkets , banks of rivers).
Incredibly dangerous bacterial disease , in which the bacteria destroy the brain and spinal cord membrane. The main victims of meningococcus are children and the elderly. Up to 50% of cases end in the death of the sick. But those , who are able to recover , not get rid of the serious consequences of the disease.
We are very aggressive disease symptoms , which appear one after the other, and can result in death within days.
The source of infection are sick people and bacteria carriers. Route of transmission – airborne ,truth , to infect need pretty close contact with the patient. The disease can be prevented thanks to the vaccine. Today, there is a vaccine against all strains of meningococcal infection , including the newest serogroup B.
Diseases of the brain are a huge problem all over the world. Cerebrovascular disease – is a group of diseases , characterized by damage to blood vessels in the brain: ischemic stroke , intracerebral hemorrhage and others. Usually, these diseases result in neglected atherosclerosis and hypertension.
Disorders of cerebral circulation are the second most common cause of death in the group of diseases of the cardiovascular system after ischemic heart disease.
How to avoid? Very simple: you need to stop smoking , control your weight , maintain a healthy sleep , avoid stress ( haha) and not neglect inspections , if you are at risk. The most important thing is to monitor the pressure.
Remember , how to quickly determine the stroke ( 4 features):
ask the person to smile. If a one-sided grin emerged instead of a smile, it’s bad;
ask to say a simple phrase – speech should not be slowed down;
ask them to raise both hands – he must raise them at the same time;
ask to stick out your tongue – it should not be turned to one side.
Acute intestinal infection , which develops after , you drank dirty water or ate something , that has been infected by the bacterium Vibrio cholerae. Sometimes cholera kills a person in a few hours: everything begins with severe diarrhea , dehydration occurs , then death.
The simplest prevention is the usual sanitary and hygienic measures: disinfection of water ,washing hands , heat treatment of food , disinfection of common areas. But if you go to the area ,where he meets this dangerous bacteria , it is best to make a cholera vaccine.
However , with timely and adequate treatment, the prognosis is favorable.
Things to Remember :
- If you are going on vacation , be sure to find out , what diseases are endemic to the area , where you’re going , and what vaccinations should be done.
- Watch your state of health and to consult a doctor , as soon as there are signs of malaise.
- Do not drink the water , if you are not sure of its source. If you come to the tropics , drink water from bottles , but in no case from the tap and not from the well.
- Observe basic sanitary and hygienic standards.
- Do not make contact with strangers, and even more so with wild animals.
