How Malaria Spreads and Kills and How to Help


Is there anything in the world more precious than a baby who’s safe and sound in dreamland? Parents do everything they can to protect their children from harm. Unfortunately, some of the most dangerous risks are unavoidable without help. Many exist just because of where a family happens to live.

Malaria is one such risk, and it has no respect for the age, fragility or innocence of a person.

Malaria is no ordinary disease. You’ve heard of it, almost certainly. You probably have a general idea about how it spreads and in which parts of the world it tends to thrive. But do you know what really happens when a person is infected? And are you aware that the world’s first malaria vaccine has only recently entered testing in the field?

It’s an age-old problem that still needs a definitive solution.

How old? According to the Journal of Infectious Disease, Hippocrates, widely regarded as the father of medicine, discussed a disease that many believe was malaria. Modern scientists have also discovered infected mosquitoes preserved in primitive samples of Baltic amber.

It seems to have nearly always been around. But stopping it has been proven to be an insurmountable task. Malaria-preventive medications exist, but a vaccine has been a long and laborious journey. While mosquito netting seems like an ordinary thing, it has the power to save lives by preventing mosquito bites. Netting isn’t new or fancy, but it’s on the front lines of defense, especially in parts of the world where medical care is more difficult to find.

Galatians 6:2 tells us, “Bear one another’s burdens, and so fulfill the law of Christ.” Through the combined efforts of devoted missionaries, the World Health Organization (WHO) and several other globally recognizable organizations and foundations hard at work, we can protect against this terrible disease and cure it when it happens.

Gospel for Asia is involved in the good fight to protect people from malaria. GFA has distributed hundreds of thousands of mosquito nets to people throughout South Asia who could die without them. In 2017 alone, GFA distributed over 300,000 mosquito nets.

What Exactly is Malaria?

Malaria isn’t a bacterial or viral infection; it’s a tiny parasite called plasmodium, which has five known types, according to the Centers for Disease Control (CDC).
  • Plasmodium vivax
  • malariae
  • ovale
  • falciparum
  • knowlesi
Of these, P. vivax and P. falciparum are the most common. Of the two, P falciparum is the deadliest form. It’s also the most common in sub-Saharan Africa. P. knowlesi often infects primates, but it can also infect humans, specifically people living and traveling in Southeast Asia.

Each type of malaria has its own nature, but all infections have a similar course. First, they travel to the liver of the infected person, where they pause and multiply. Then they infect the red blood cells, where they multiply and spread.

Depending on the age and health of the infected person, symptoms emerge between one and two weeks after being infected with the parasites. The first symptoms, says WHO, are similar to a bout with the flu: fever, chills, headache and vomiting.

Fortunately, malaria is often curable. However, a cure depends on timely diagnosis, the right medication—and enough of it. Caught early, medication eliminates the parasite. Unchecked, a person infected with the parasites can die.

Without treatment, or without the correct medication for the person, malaria advances by destroying red blood cells and blocking capillaries to vital organs, which can end in organ failure and death.

Malaria preventive medications kill the parasites if they enter the body. Several such medications exist, but not every drug is right for every person. For people traveling where malaria is a problem, they offer reliable protection. But for people living where malaria is always a risk, daily medications aren’t a viable solution.


How Does the Malaria Disease Keep Spreading?

The plasmodium parasite is only transmitted by female mosquitoes of the Anopheles genus. Female Anopheles mosquitoes don’t inherently carry the parasite as part of their biological makeup, so not all of them can infect a person. However, WHO explains that all malaria-carrying mosquitoes that transmit the disease to humans are the female Anopheles.

Anyone who welts up and itches practically at the thought of a mosquito knows these insects are nearly always hungry. They bite humans to find a blood meal, which helps them nourish their eggs. When the right mosquito takes a blood meal from a person with malaria, the parasite enters the insect’s body, where it reproduces. The cycle for that mosquito has then begun.

But mosquitoes don’t bite in the truest sense of the word, and they also do more than extract blood. Infection begins with an injection.

The familiar sting comes from the proboscis, which is the scientific name for a mosquito’s long, multi-prong, needle-like nose. The bite is really a stab, which allows the mosquito to withdraw blood and inject its own saliva. Plasmodium parasites thrive in the saliva of infected female Anopheles mosquitoes.

Once the mosquito extracts malaria parasites from its victim, the parasites reproduce inside the insect’s body. The next time the mosquito needs a blood meal, the stab injects parasites into its new victim while it extracts blood. The more people it bites, the more people it infects, and the more people who carry the malaria parasite to infect more and more female Anopheles mosquitoes.

It’s a vicious, unrelenting cycle.

Generational Poverty: A Cycle Not Worth Repeating

Image
The cycle of generational poverty can seem impossible to break. Children inherit what their parents teach and show them. a joint report from Ascend: The Aspen Institute and Bernard van Leer Foundation affirms this. “What young children learn from the adults who raise and care for them lays the foundation for future social, emotional, language, and cognitive growth,” the report says. 1 Children raised in a generational poverty mindset often lack the tools they need to succeed or achieve a better life than that of their parents. As adults, these individuals often then raise their children in poverty similar to that of their own childhoods, and the cycle perpetuates. It’s a cycle not worth repeating, yet it does time and time again. For the 736 million people worldwide living below the poverty line, earning $1.90 a day or less, the focus is frequently on mere survival. 2 Children are disproportionately affected by extreme poverty, says UNICEF, as “children who grow up impoverished often...

What Is the Poverty Cycle?

Image
The question, “What is the poverty cycle, or cycle of poverty?” is one that must be answered to address and end poverty across the globe. Put simply, the term refers to the trend where the vicious effects of poverty and deprivation pass from one generation to the next, with no seeming way out. [1] Someone born into poverty has fewer opportunities than their wealthier peers. They must focus on survival above all, leaving little room for anything else. One illness can wipe out a family’s savings, but the unclean water sources and lack of protection available to them invite sickness. Walking to retrieve water can be time-consuming yet must be a daily priority, and many children must work alongside their parents for the family to afford food. Thus, school is often a far-off dream. Having had few opportunities to acquire skills, the kids grow up to repeat the cycle of poverty with their own children. This story was all too familiar for Nalah. His father worked in the tea fields, trying to e...

What Do I Need to Know about the Global Poverty Rate?

Statisticians are getting better at measuring the global poverty rate every year. The World Bank is one group working hard to accurately measure it so that the extent of the problem is fully known and so that progress can be measured. [1] Through governments and non-governmental organizations (NGOs), we can more clearly see the last decade of progress and the most recent effects driving poverty rates. Sub-Saharan Africa has been one area difficult to measure, but new data shows an overall reduction in the percentage of those in poverty. Unfortunately, there is an increase in total number of people living at or below the official poverty rate of $1.90 per day. [2] That doesn’t mean that all hope is lost. With good statistics and a clear view of the problem, countries and organizations can use the proven methods to regain any ground lost. Additionally, valuable lessons have been learned about how to protect the most vulnerable and how to prevent some of the worst effects. GFA World is un...
