What are the Symptoms, causes & treatment of Dengue fever?

Dengue fever is a mosquito-borne viral infection that's becoming more common in many parts of the world.

A severe flu-like illness with muscle and joint pain, rash, headaches, nausea, and vomiting can be accompanied by a variety of other symptoms which include inflammation of the eye or gums causing pus build-up or tooth loss. Visiting a doctor is advisable if the headache lasts for more than 3 days; there are sudden meteors in vision;

The virus lives inside mosquitoes and is transmitted to humans through their saliva when they take a blood meal from an infected person. Vivax mosquitos tend to bite both day time and night time, while Aegypti mosquito prefers only night time

Dengue fever is caused by the dengue virus, which is spread to people through mosquito bites.

The four types of dengue virus cause similar illnesses however the risk for severe disease and death increases with successive infections due to how it affects your body's immune system. The most common symptoms include high fever, headache, sore throat, nausea or vomiting (only in some cases), fatigue or lack of strength (maybe unrelated), pain behind the eyes (called "photophobia"), and rashes on arms, legs buttocks.

  • Flu-like symptoms
  • Rash on the wrists, arms, legs & trunk of the body.
  • Joint pain or muscle pain
  • Nausea

Treatment: Pain medications and fluids to maintain adequate hydration. Low platelet count requires blood transfusion for carriers of thalassemia. Low platelet count is treated with plasma exchange therapy or immune globulin infusions. Dengue hemorrhagic fever is also treatable but the outcomes are bad if not caught early on. Death rate increases with the severity of dengue infection (DHF). DHF patients need IV fluids, clean water preparation techniques, antibiotics, antiemetics, and antipyretics; ideally in a hospital setting.

Dengue Fever is a viral infection transmitted primarily by mosquitoes. The virus infects the human ribonucleic acid (RNA) and affects platelets which become unstable and may lead to internal bleeding.

Symptoms of dengue fever include the following: high fevers which can reach up to 106 degrees Fahrenheit, headache, pain behind the eyes, joint pains, skin rash that looks like measles, or prickly heat. In some cases, it may be necessary for patients who experience unusual bleeding or persistent vomiting to get fluids intravenously (IV). For severe cases, hospitalization may be necessary with supportive measures such as maintaining fluid levels with IV fluids and careful monitoring of blood pressure.

Very feverish and break out in a rash. Treatment for Dengue Fever is rest, fluids, and aspirin or paracetamol to relieve pain. If someone has a loss of appetite or is unable to keep down fluids, seek medical help right away. Otherwise drink plenty of fluid such as water, cordial lime drinks such as Fanta. Avoid alcohol and caffeine because there can be low blood pressure associated with this illness which will cause more dehydration while worsening the symptoms. Symptoms usually start between 4-7 days after being bitten by an infected mosquito but may start anytime from 14-22 days following a bite from an infected mosquito depending on what type of virus was transmitted that infection period depends on your immune system.

Dengue fever is an infection of the human body by one of four closely related dengue viruses. It's typically carried by mosquitoes, prevalent in tropical and subtropical regions throughout the world. The symptoms which are experienced are fevers, joint pains, severe headache, nausea, at times secondary bacterial infections that can be fatal to sufferers with other pre-existing health conditions. Diagnosis is through blood tests following possible exposure. Prevention involves mosquito control measures such as mosquito repellents and the elimination of mosquito breeding grounds. There is no universally accepted treatment for this particular illness yet though there have been trials done on animals so there might be after all good news for us down the road.

Dengue fever is a mosquito-borne tropical disease. Signs and symptoms may include mild fever, headache, pain behind the eyes, muscle aches, joint pains, nausea, or vomiting. The key to treatment is prevention against mosquitoes through avoidance of mosquito bites and use of insect repellents.

Mild cases usually get better without any specific treatment by 6 to 10 days. Use painkillers for the headache, drink plenty of fluids for persistent vomiting or nausea or other signs that develop after ten days or more that are not improving gradually on their own. Seek immediate medical attention if you have difficulty breathing(especially when accompanied by a cough), your skin is clammy with generalized discomfort("body aches"), unusual bleeding.

There are many symptoms of dengue fever, including headaches, nausea, and vomiting, pain behind the eyes both at rest and with movement. Joint pains are common too. There is no specific way to prevent dengue but prevention can be attempted through controlling mosquito populations in urban areas. There's no specific treatment available for this disease, though once it begins to recede patients can use acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs).

The fever is as high as 104 degrees Fahrenheit and causes debilitation, dehydration, abdominal pain and headache. The Dengue virus causes the flu-like illness Dengue Fever. Symptoms include a sudden high fever accompanied by headaches, muscle aches, and extreme tiredness. It might seem like a minor cold but it can be potentially fatal and needs to be treated as an emergency if not diagnosed correctly in time.

This mosquito-borne disease also has far more serious consequences including internal bleeding called dengue hemorrhagic fever that can lead to death from shock or multiple organ failure after subsequent infection with other bacteria or parasites from contaminated surfaces such as water droplets on door handles of public buildings.

Dengue fever is a viral hemorrhagic fever and quickly becomes life-threatening, resulting in an extremely high mortality rate. Symptoms include high fever, skin rash (large red patches), joint pain, headache, nausea and vomiting, muscle and bone aches. Treatment includes keeping fluids up by taking electrolyte drinks such as Pedialyte or Gatorade which supplies the water and sodium your body needs to function properly. Avoid sugar drinks because they can make you sicker if you're not getting enough sugar. Get plenty of rest and lots of hydration for the best results!

Cardiac Arrest

Understanding Cardiac Arrest: Causes, Symptoms, and Life-Saving Actions

Cardiac arrest is a serious and sudden medical emergency. It happens when the heart unexpectedly stops beating. This condition cuts off blood flow to the brain and other vital organs, and without quick treatment, it can lead to death within minutes.

Even though the term might sound scary, the good news is that understanding cardiac arrest can help you act quickly and potentially save a life. In this blog, we’ll explore what cardiac arrest is, why it happens, the warning signs, and how to respond if it ever occurs.

 

What Is Cardiac Arrest?

Cardiac arrest is when the heart stops pumping blood throughout the body. This is usually due to a problem with the heart's electrical system. Without a regular heartbeat, the brain, lungs, and other organs don’t get the oxygen they need, which can cause a person to collapse and become unresponsive.

It's important to know that cardiac arrest is not the same as a heart attack. A heart attack happens when blood flow to a part of the heart is blocked. Cardiac arrest, on the other hand, is when the heart suddenly stops beating altogether. A heart attack can sometimes lead to cardiac arrest, but the two are different conditions.

 

What Causes Cardiac Arrest?

Cardiac arrest can be caused by several different factors, including heart-related and non-heart-related issues. The most common causes include:

1. Abnormal Heart Rhythms (Arrhythmias)

The most common cause of cardiac arrest is an arrhythmia called ventricular fibrillation. This happens when the heart beats in a fast and irregular way, preventing it from pumping blood properly.

2. Heart Attack

A heart attack can damage the heart's electrical system and trigger cardiac arrest. If the heart muscle is injured, it may not beat correctly.

3. Heart Disease

People with coronary artery disease, heart failure, or cardiomyopathy (disease of the heart muscle) are more likely to experience cardiac arrest.

4. Congenital Heart Conditions

Some people are born with heart abnormalities that increase the risk of cardiac arrest, especially in young athletes.

5. Drug Overdose or Substance Abuse

Illegal drugs like cocaine or meth, or even certain prescription medications, can interfere with the heart’s rhythm and lead to cardiac arrest.

6. Severe Blood Loss or Oxygen Shortage

Situations such as drowning, choking, or serious injury can reduce oxygen levels in the body, causing the heart to stop.

 

Who Is at Risk?

Cardiac arrest can happen to anyone, but some people have a higher risk than others. Risk factors include:

  • History of heart disease or previous heart attack
     

  • High blood pressure or high cholesterol
     

  • Diabetes
     

  • Smoking
     

  • Obesity
     

  • Sedentary lifestyle
     

  • Family history of sudden cardiac arrest
     

  • Use of recreational drugs
     

Even athletes and young people can suffer from cardiac arrest, especially if they have an undiagnosed heart condition. That’s why regular health checkups are essential.

 

Signs and Symptoms of Cardiac Arrest

Cardiac arrest usually happens suddenly and without warning. A person may:

  • Collapse without any reason
     

  • Lose consciousness immediately
     

  • Stop breathing or gasp for air
     

  • Have no pulse
     

Sometimes, a person may have warning signs just minutes before cardiac arrest, such as:

  • Chest discomfort
     

  • Rapid or irregular heartbeat
     

  • Dizziness or fainting
     

  • Shortness of breath
     

If you notice any of these symptoms, especially in someone with heart disease, take it seriously and seek medical help.

 


What to Do in Case of Cardiac Arrest?

When cardiac arrest happens, every second counts. Here’s what you need to do immediately:

1. Call Emergency Services

Call your local emergency number right away (e.g., 911). Tell them it's a suspected cardiac arrest so they send help quickly.

2. Start CPR

Begin chest compressions immediately. Push hard and fast in the center of the chest (about 2 inches deep) at a rate of 100 to 120 compressions per minute. If you're trained, you can also give rescue breaths.

3. Use an AED

An Automated External Defibrillator (AED) is a device that can help restart the heart. If one is available nearby, use it as soon as possible. AEDs are designed to be simple to use, even for people without medical training.

The combination of CPR and an AED can greatly increase the chance of survival until professional help arrives.

 

How Is Cardiac Arrest Treated?

Emergency responders may use advanced tools and medications to stabilize the heart. After arriving at the hospital, doctors may:

  • Run tests to find the cause of the arrest
     

  • Use defibrillation again if needed
     

  • Provide medications to support heart function
     

  • Implant a device called an ICD (Implantable Cardioverter Defibrillator) in people at high risk to prevent future arrests
     

Ongoing care may also involve lifestyle changes, medications, and treating underlying conditions like high blood pressure or arrhythmias.

 

Can Cardiac Arrest Be Prevented?

Yes, in many cases, cardiac arrest can be prevented by leading a heart-healthy lifestyle and managing medical conditions early. Here’s how:

  • Exercise regularly
     

  • Eat a heart-healthy diet rich in vegetables, fruits, lean proteins, and whole grains
     

  • Avoid smoking and excessive alcohol
     

  • Keep your blood pressure, cholesterol, and blood sugar under control
     

  • Manage stress through mindfulness, meditation, or hobbies
     

  • Get regular check-ups, especially if you have a family history of heart issues
     

If you’ve already had a heart attack or have known heart problems, your doctor might recommend medications or devices like an ICD to reduce your risk of cardiac arrest.

 

Why CPR and AED Training Matter

Every minute without CPR reduces a cardiac arrest victim’s chance of survival. If more people knew how to perform CPR and use an AED, many lives could be saved every year.

Consider taking a CPR training course in your community. It’s a small investment of time that can make a huge difference in someone’s life—even a stranger's.

 

Conclusion

Cardiac arrest is a sudden and life-threatening condition that can affect anyone, regardless of age or health. Recognizing the warning signs, understanding the risk factors, and knowing how to respond with CPR or an AED can mean the difference between life and death. While it’s a frightening topic, being informed and prepared can help you protect yourself and your loved ones.
