Malaria is
a serious and sometimes life-threatening tropical disease that spreads
through parasites.
It kills more than 445,000 people a year, many of them children in Africa alone. Countries with warmer climates which are hot
enough for malaria parasites and mosquitoes help them to thrive. These regions include sub-Saharan Africa, Southeast
Asia, Latin America, and the Middle East.
Before
you travel, check the CDC’s website to see whether your destination is a
hotspot for malaria. You may have to take pills before, during, and after your
trip to lower your chances of getting it. {keep
that in mind}
Why Malaria Is Harmful
Malaria
can cause high fever,
chills, and flu-like symptoms that can be life-threatening when not treated
quickly. The disease is caused by Plasmodium parasites, which
are carried by Anopheles mosquitoes
How Malaria
Is Spread
Only female mosquitoes spread the malaria
parasites. When a mosquitoe bites a person who already has malaria, it sucks up the person’s blood,
which contain the parasites. When the mosquitoe bites its next victim, it injects the
parasites into that person. That’s how the disease is spread.
Once the parasites enter your body, they travel to your liver, where they multiply. They invade
your red blood cells, which are important cells in
your blood that carry oxygen. The parasites get inside them, lay their eggs,
and multiply until the red blood cell bursts.
This releases more parasites into your bloodstream. As
they attack more of your healthy red blood cells, this infection can make you
feel very sick.
Types of Malaria
There are five species of Plasmodium parasites
that affect humans. Two of them are considered the most dangerous:
- P. falciparum. This is the most common malaria parasite in Africa,
and it causes the most malaria-related deaths in the world. P.
falciparum multiplies very quickly, causing severe blood
loss and clogged blood vessels.
- P. vivax . This is the malaria parasite most commonly found
outside of sub-Saharan Africa, especially in Asia and Latin America. This
species can lie dormant, then rise up to infect your blood months or years
after the mosquito bite.
Symptoms
Symptoms for malaria usually start about 10 to 15 days after the
infected mosquito bite. Here are some things to keep in mind, though:
- Because
the signs are so similar to cold or flu symptoms, it might be hard to tell
what you have at first.
- Malaria symptoms don’t always show
up within 2 weeks, especially if it’s a P. vivax infection.
- People
who live in areas with lots of malaria cases may become partially immune
after being exposed to it throughout their lives.
How Confirm If You Have Malaria
Simply a blood test would
confirm whether you have malaria. Along with high fever, shaking chills
and sweating, symptoms can include:
- Throwing
up
(Constipation)
- General weakness
- Laziness to rise in the morning
- Headache
most times constant
- Diarrhea
- Being
very tired (fatigue)
- Body
aches
- Yellow skin (jaundice) from losing red blood cells
- Kidney failure
- Seizure
- Confusion
When to Call a Doctor
Given how quickly malaria can become
life-threatening, it’s important to get medical care as quickly as
possible. Young children, infants, and pregnant women have an especially high
chance for severe cases of malaria.
Seek care if you’re getting high fever
while living in or traveling to an area that has high chance for
malaria. You should still get medical help even if you see the symptoms
many weeks, months or a year after your travel or feel contact with mosquitoes.
