When it comes to diseases that scare people the most, many of us immediately think of cancer and AIDS. Earlier we wrote about the signs that may indicate the risk of developing the former and the myths about the latter. Tularemia, Ebola virus, and anthrax are also characterized by high mortality rates. However, there are 3 more lethal diseases everyone needs to be able to recognize the symptoms of.
This bacterial disease of the small intestine is transmitted mainly through contaminated water and food. Without treatment, cholera can turn fatal, even for a previously completely healthy person, due to severe dehydration. It is believed that the risk of getting infected is rather low in industrialized countries, and serious symptoms develop only in 1 out of 10 cases. Cholera is easily treated when timely diagnosed.
- nausea and vomiting;
- intense thirst;
- dry mouth;
- dry skin;
- absent urination;
- low blood pressure;
In the case of electrolyte imbalance, there is also a risk of muscle spasms and shock. To avoid contamination, consume only clean water, and maintain personal hygiene and rules of food processing.
2. Dengue fever
This debilitating infectious disease is typical for tropical countries as it is mosquito-borne. This illness manifests itself on the 3-14th day after getting infected, but with the timely diagnosis the recovery period is about 1 week.
- sudden fever;
- rashes on the skin (appears on the 2-5 day after fever);
- pain in the head and eyes;
- nausea and vomiting;
- severe joint and muscle pain;
- nose and mouth bleeds.
When symptoms are not severe, dengue fever is easily mistaken for ARVI or flu. Unfortunately, there is no vaccine or effective treatment for this disease. The best way to prevent infection is to use repellents.
3. Meningococcal meningitis
Meningococcal infection is fraught with a risk of meningitis (inflammation of the membranes of the brain and spinal cord), which can be mistaken for the flu, sinusitis, or ear infection. The bacterial form can infect blood and lead to sepsis, as well as various mixed varieties of the disease. Other dangerous consequences are purulent meningitis and meningoencephalitis.
- rash (small spots on the body);
- shock conditions.
Compliance with rules of hygiene and limiting interaction with people showing signs of any infectious disease can significantly reduce the risk of infection.
These diseases are transmitted mainly through tactile contact or by airborne transmission (except for those transmitted by insects or animals). To protect yourself, it is advised to follow a few simple rules.
- Watch the food you eat. Don’t buy groceries in questionable places, and wash and cook food properly.
- Observe hand hygiene.
- Monitor water quality.
If you suspect any of the infections above, be sure to consult a doctor. When it comes to making a correct diagnosis, every little bit of information matters: don’t withhold anything from your doctor!
