These 10 diseases share one common trait – they are deadly. From the first signs, immediate medical attention is critical.
1. Meningococcal Meningitis
Meningococci bacteria live in about one in ten people, residing in the throat. Usually, they stay inactive, but for unknown reasons, they can activate, especially in children and teenagers, leading to an infection that affects the brain and spinal cord. Prompt treatment yields a favorable prognosis in 5 out of 6 cases.
**Warning Signs:**
– High fever and severe headache
– One or more red spots that don’t vanish under skin pressure
– Stiff forehead
– Sensitivity to light and noise
The bacteria are fragile outside the throat environment and spread through close contact like kissing. The meningococcal C vaccine is recommended for children and teens up to 24 years old.
2. Necrotizing Fasciitis – “Flesh-Eating” Disease
Although rare, this severe bacterial skin infection leads to amputations and has a 25% mortality rate. It spreads through the connective tissues surrounding muscles, nerves, and blood vessels.
**Warning Signs:**
– Severe pain from a minor skin irritation
– Red, swollen, shiny skin
– Blisters followed by bleeding
– Numbness as tissues die (necrosis)
3. Sudden Cardiac Arrest
With sudden heart stoppage, intervention within 8 minutes is critical for survival.
**Cause:**
Typically, this occurs due to a myocardial infarction but can also happen from drowning, electric shock, or drug overdose.
**First Aid:**
– Call 911 immediately with the precise location.
– Perform chest compressions.
– Use a defibrillator if available nearby.
4. Septic Shock
The leading killer in emergency rooms, caused by overwhelming bacterial, viral, or fungal infections. Despite medical advancements, it’s fatal in 50% of cases.
**How It Happens:**
It starts as an infection in the lungs or digestive system, sometimes the urinary tract. Bacteria multiply rapidly, overwhelming the body.
5. Anaphylactic Shock
The most severe allergic reaction, triggered by allergens like food, medications, or bee stings. It requires immediate adrenaline injection.
**Warning Signs:**
– Breathing difficulty
– Hives
– Swelling of the face, eyelids, and lips
– Digestive issues (diarrhea, pain, vomiting)
6. Stroke (Brain Vascular Accident)
The leading cause of death in women and severe disability in both sexes. It happens when blood flow is blocked in a brain vessel.
**Warning Signs:**
– Weakness on one side of the body
– Speech difficulties
– Facial drooping
**Prevention:**
Managing high blood pressure is crucial to prevent strokes.
7. Pulmonary Embolism
It can strike healthy individuals abruptly, caused by a blood clot blocking a lung vessel, often originating from a leg clot.
**Warning Signs:**
– Sharp chest pain mimicking a heart attack
– Sudden shortness of breath
– Coughing, sometimes with bloody mucus
Death results from heart failure.
8. Acute Pancreatitis
In 10% of cases, this condition where the pancreas digests itself is fatal. The primary symptom is severe abdominal pain.
**Cause:**
Pancreatic enzymes stuck due to a blocked duct start damaging the pancreas.
**Prevention:**
Avoid triggers like bile duct diseases, alcohol abuse, metabolic disorders, and pancreatic-toxic drugs.
9. Ectopic Pregnancy
Severe abdominal pain and missing periods or dark bleeding can indicate an ectopic pregnancy, often in a uterine tube. If untreated, the tube can rupture, causing hemorrhage.
**Solution:**
Early diagnosis and surgery are essential.
10. Aortic Dissection
A serious condition that causes death in 50% of cases if not promptly diagnosed. It involves the tearing of the aortic wall, causing sharp, severe pain.
**Risk Factors:**
High blood pressure, Marfan syndrome, or family history.
**Treatment:**
Focus on managing cardiovascular complications to reduce death risk.
