Malaria Transmission

Published

on

Malaria transsmission. Humans contract malaria mostly by the bite of a female Anopheles mosquito carrying the infection. The malaria parasite is consumed by the mosquito when it bites an infected human. The infection cycle can be continued approximately a week later when the same mosquito bites another person and injects the parasite into their bloodstream through its saliva. Less frequently, using tainted syringes or needles or receiving blood transfusions can spread malaria.

MALARIA TRANSMISSION

Malaria continues to pose a serious threat to world health, especially in tropical and subtropical areas. Reducing the risk of infection and successfully managing the condition require an understanding of the symptoms, mechanisms of transmission, and preventive actions. The burden of malaria can be lessened and eventually eradicated with sustained efforts at mosquito control, the use of insecticide-treated nets, drug prevention, and public health campaigns.

Transmission of malaria;

Malaria is transmitted by the bite of an infected Anopheles mosquito. The mosquito injects Plasmodium parasites into the bloodstream, where they travel to the liver, mature, and then re-enter the bloodstream to infect red blood cells. There are five species of Plasmodium that can infect humans, with Plasmodium falciparum being the most deadly.

Symptoms of malaria;

Symptoms of malaria typically appear 10 to 15 days after the infected mosquito bite. They can include:

Fever: High, recurring fevers are a hallmark of malaria.

Chills: Intense chills and shivering often accompany fever episodes.

Headache: Severe headaches are common.
• Muscle and Joint Pain: Muscle aches and joint pain are frequent symptoms.

Fatigue: Profound fatigue and general malaise.

Nausea and Vomiting: Gastrointestinal symptoms may occur.
• Sweating: Profuse sweating often follows fever episodes.

In severe cases, malaria can cause complications such as anemia, respiratory distress, organ failure, and cerebral malaria, which affects the brain and can be fatal if not treated promptly.

Prevention;

Preventing malaria involves a combination of measures to avoid mosquito bites and control mosquito populations. Key preventive strategies include:

Use Insect Repellents: Apply repellents containing DEET, picaridin, or oil of lemon eucalyptus to exposed skin.

Sleep Under Mosquito Nets: Use insecticide-treated mosquito nets (ITNs) when sleeping, particularly in areas with high malaria transmission.

Wear Protective Clothing:

Wear long-sleeved shirts, long pants, and socks to reduce skin exposure.

Indoor Residual Spraying: Spraying the interior walls of homes with insecticides can help reduce mosquito populations.

Eliminate Standing Water: Remove or manage standing water where mosquitoes breed, such as in containers, puddles, and stagnant ponds.

Antimalarial Medications: For travelers to malaria-endemic areas, taking prophylactic antimalarial drugs can reduce the risk of infection. Consult a healthcare provider for recommendations based on travel destination.

Treatment;

Prompt treatment is crucial for malaria, especially for infections caused by Plasmodium falciparum. Treatment typically involves antimalarial medications, such as:

Artemisinin-based Combination Therapies (ACTs): These are the most effective treatment for P. falciparum malaria.

Chloroquine: Used for infections caused by P. vivax, P. ovale, P. malariae, and some strains of P. falciparum in regions where resistance to chloroquine is not a concern.

Other Medications:

Depending on the specific parasite species and resistance patterns, other drugs like mefloquine, quinine, or primaquine may be used.

 

 

 

Summary

Plasmodium parasites cause malaria, a potentially fatal illness that is spread to humans via the bites of female Anopheles mosquitoes carrying the infection. Malaria is still a serious public health concern in many regions of the world, especially in sub-Saharan Africa, despite tremendous international efforts to prevent and eradicate it.

Why feel cold always

Published

Why feel cold always. Everybody’s body responds to cold in a somewhat different way, and some people experience cold more frequently than others. We refer to this as cold intolerance. There are several possible causes of feeling chilly all the time, and these causes may include a variety of symptoms. Certain symptoms may seem like insignificant irritations, but others may indicate a more serious underlying illness. If you feel cold all the time despite covering up and taking other steps to stay warm, you could have an underlying ailment that’s generating this discomfort.

WHY FEEL COLD ALWAYS

1. Low body weight;

Muscle mass and fat assist the body stay warm. Heat is produced by moving muscles and fat insulates. You may be more sensitive to chilly temperatures if you have recently dropped a large amount of weight or if you have always been slender.

2. Skipping meals;

Although its uncommon for anemia to produce a really frigid feeling, it might cause a person to feel cold. An anemia test can be performed.

4. Raynaud’s phenomenon;

In order to keep the internal organs warm, our body’s natural reaction to cold weather is to draw blood away from the skin. That instinctive reaction is severe in those who have Raynaud’s phenomenon. Blood flow to the skin is substantially reduced as a result of the microscopic blood vessels becoming excessively restricted; this usually affects the fingers and toes. For a brief while, one or more digits become blue or white. Individuals who have this illness typically react considerably more strongly to even little temperature dips.

5. An under active thyroid;

Ulcer causes and types

Published

on

Ulcer causes and types. An ulcer is a painful sore that heals slowly and occasionally comes back. Ulcers are not unusual. Their underlying reasons usually determine why they manifest and the symptoms that accompany them.
Ulcers can appear anywhere in or on your body, from the lining in your stomach to the outer layer of your skin.
Ulcers can occasionally go away on their own. In other cases, they need medical care to avoid major issues.

ULCER CAUSES AND TYPES

An ulcer is an open sore on the lining of the stomach, small intestine, or esophagus (peptic ulcer), or a rupture in the skin or mucous membrane.Long-term use of NSAID painkillers and an H. pylori bacterial infection are the two most frequent culprits.

Peptic ulcers, another name for ulcers, are open sores in the upper portion of the small intestine or stomach lining. The mucus lining the inside of your digestive tract becomes eroded by stomach acid, resulting in the formation of an ulcer.

Types of peptic ulcers

1. Gastric ulcer: It happens when a sore develops in the stomach lining.

2. Duodenal ulcer: This is the result of an upper intestinal sore developing.

3. Esophageal ulcer: This is the process by which a sore develops in the lining of your esophagus, the tube that travels from your throat to your stomach to carry food and liquids.

Prior until the mid 1980s, the general consensus was the ulcers were caused by stress, a genetic predisposition to increased  acid secretion, and unhealthy lifestyle choices ( such as bingeing on rich, fatty foods, alcohol, caffeine and smoke). It was thought that these conditions would cause an accumulation of stomach acids which could damage the lining that protects the stomach, duodenum, or esophagus.

Although excessive release of  acid undoubtedly contributes to the formation of ulcers, a more recent idea suggests that bacterial infection is the main cause of peptic ulcers. since the mid 1980s, research has indicated over 80% of stomach ulcers and over 90% of duodenal ulcers are caused by the bacteria Helicobacter pylori, or H. pylori more recent data, though, shows that those percentages are falling.

Most likely, you’ll have discomfort or scorching ache between your breastbone and belly button. When you’re empty handed, such at night or in between meals, you can sense it more than usual. If you take an antacid, the pain can go away for a short while, but it might come back.

The discomfort may come and go for several days or weeks, lasting a few minutes or several hours.

Other symptoms may include:
