Parasitic Diseases !
Have you ever wondered what parasites are? They're basically
tiny germs that live on or inside another living thing to get their food. When
these germs enter our bodies, they cause diseases we call parasitic diseases.
The most common way they spread is through the bite of an infected insect.
We hear diseases like malaria and dengue
fever—these are two of the most common parasitic diseases that everyone
knows about. In this blog post, we'll learn more about these illnesses. We'll
find out what causes them, which insects carry the germs, and the main signs
and symptoms you need to look out for.
=================================================================
Malaria
Cause: A single-celled parasite called Plasmodium.
Vector: The female Anopheles mosquito.
Symptoms: High fever, shivering chills, and sweating that often occur in cycles.
Prevention: Using mosquito nets while sleeping, wearing protective clothing, and using mosquito repellents.
Dengue Fever
Cause: A virus called the dengue virus.
Vector: The Aedes aegypti mosquito.
Symptoms: High fever, severe headache, pain behind the eyes, and joint and muscle pain (earning it the nickname "breakbone fever").
Prevention: Eliminating stagnant water where these mosquitoes breed (like in pots, old tires, or coolers) and using mosquito repellents.
Filariasis (Elephantiasis)
Cause: Tiny parasitic worms, also known as filarial worms.
Vector: Various types of mosquitoes, including Anopheles and Culex.
Symptoms: The worms block the lymphatic system, leading to severe swelling and thickening of the skin, most commonly in the legs and arms. This is where the name "elephantiasis" comes from.
Prevention: Avoiding mosquito bites and, in endemic areas, taking specific medicines to kill the worms.
Intestinal Parasites (Worms)
Cause: Various types of worms, such as roundworms (Ascaris lumbricoides), hookworms, and tapeworms. These are not transmitted by mosquitoes but are a common school-level topic for parasitic diseases.
Vector: Contaminated food, water, or soil.
Symptoms: Abdominal pain, weight loss, and in severe cases, malnutrition.
Prevention: Maintaining good hygiene, such as washing hands before eating and after using the toilet, and ensuring food and water are clean.
Chikungunya
Cause: Chikungunya virus.
Vector: The Aedes aegypti mosquito, which is the same mosquito that causes dengue.
Symptoms: Sudden high fever, severe joint pain (which is the most common and distinguishing symptom), headache, and a rash. The name "Chikungunya" means "to become contorted" in the Makonde language, referring to the stooped posture people adopt to cope with the joint pain.
Prevention: The same measures as dengue: eliminating mosquito breeding grounds by getting rid of stagnant water, and using mosquito repellents.
Zika Virus
Cause: Zika virus.
Vector: The Aedes mosquito.
Symptoms: Many people have no symptoms, but those who do may experience fever, rash, joint pain, muscle pain, and red eyes.
Prevention: Avoiding mosquito bites by using repellent and wearing protective clothing. It's also important to note that Zika can be transmitted sexually.
Yellow Fever
Cause: Yellow fever virus.
Vector: The Aedes mosquito.
Symptoms: Initial symptoms are similar to the flu, including fever, headache, back pain, and muscle aches. In severe cases, it can cause high fever, bleeding, and jaundice (yellowing of the skin and eyes), which is where the disease gets its name.
Prevention: There is a safe and effective vaccine available for yellow fever, in addition to preventing mosquito bites.
Japanese Encephalitis
Cause: Japanese encephalitis virus (JEV).
Vector: The Culex mosquito.
Symptoms: Most people infected have no symptoms or mild flu-like symptoms. However, a small percentage can develop a serious brain infection (encephalitis), with symptoms like high fever, headache, neck stiffness, and convulsions.
Prevention: Vaccination is the best way to prevent Japanese encephalitis. You should also take precautions to avoid mosquito bites.
