Mosquitoes can spread numerous kinds of infections and diseases to humans. Two examples of this are yellow fever and malaria. While they both cause people to feel ill, they are not the same thing. Learn more about how yellow fever and malaria differ below.
When an infected mosquito bites a human, this can result in malaria. When tiny parasites can infect a mosquito, which bites a person, the parasites flow into the person’s bloodstream and multiply.
Malaria rarely occurs in developed regions of North America, but cases have been reported all over other parts of the world. Developing countries and areas with warm temperatures and high humidity are the source of most malaria transmissions. More than 90% of the cases occur in Africa among young children.
Symptoms and Treatments
Symptoms usually appear ten days to one month after a person is infected. In some situations, people do not feel sick for up to one year or several years after a mosquito bite. Parasites can live in the body for a long time, causing no harm.
Common signs of malaria are:
- Fever and sweating
- Headache and muscle aches
- Chest pain
- Nausea and diarrhea
When someone contracts malaria, they should seek treatment as soon as possible. A provider will prescribe drugs to kill the malaria parasite. Keep in mind that some parasites are resistant to malaria drugs. The kind of medication you receive and the length of treatment depend on the type of parasite affecting you.
The best form of protection is taking antimalarial medication before, during and after your trip. These medications kill the parasite before it can take hold in an individual.
Yellow fever is a viral infection spread by the Aedes aegypti mosquitoes. They thrive near human habitations and breed in clean water. These insects are familiar in parts of Africa and South America. Various travellers and residents can develop yellow fever while moving around in the elements.
Yellow fever has mild cases like malaria, but there are instances where it can become fatal. Up to 50% of people who contract the severe form of the disease wind up dying.
Symptoms and Prevention
During the first three to six days after you have developed yellow fever, you will not experience any signs or symptoms. This stage is called the incubation period. Afterward, the infection enters an acute phase. Sometimes a toxic phase results, which requires immediate action.
In the acute phase, here are signs and symptoms you can expect:
- Muscle aches
- Light sensitivity
- Loss of appetite
For this phase, signs and symptoms usually improve and are gone within several days.
Some people with acute yellow fever may enter a toxic phase. While symptoms may disappear for a day or two following the acute phase, they can return and become more life-threatening.
Toxic phase symptoms include:
- Yellowing of your skin and the whites of your eyes
- Abdominal pain and vomiting
- Decreased urination
- Slow heart rate
- Liver and kidney failure
The toxic phase can be lethal, so it is crucial to get the vaccine to prevent yellow fever when you can. Opposite of malaria, there is currently no treatment for this infection, so anyone who contracts it and becomes gravely ill will have a much harder time recovering. Before you travel to any areas with high cases of yellow fever, get vaccinated.
