Malaria and typhoid can both cause fever, weakness, headache and loss of appetite, making them easy to confuse. However, they are caused by completely different organisms and require different treatments.
Introduction
In many parts of Nigeria, it is common to hear someone say that they have malaria and typhoid after developing a fever, headache or general weakness. Sometimes both conditions are mentioned together, even when there has been no proper testing to confirm either one.
The confusion is understandable because malaria and typhoid fever can produce some similar symptoms. However, they are not the same disease.
Malaria is a disease caused by Plasmodium parasites and is commonly transmitted through the bite of an infected female Anopheles mosquito. Typhoid fever, on the other hand, is a bacterial infection caused by Salmonella Typhi, usually acquired through food or water contaminated with the bacteria.
Understanding the differences can help people seek the right treatment instead of taking medicines based only on symptoms.
What Is Malaria?
Malaria is a potentially serious disease caused by Plasmodium parasites. Infected mosquitoes transmit the parasites to humans when they bite.
Once inside the body, the parasites eventually infect red blood cells. If malaria is not treated appropriately, it can become severe and affect important organs.
Malaria is particularly important in Nigeria because the country carries a significant proportion of the global malaria burden.
What Is Typhoid Fever?
Typhoid fever is a bacterial infection caused by Salmonella Typhi. The bacteria are mainly spread when someone consumes food or water contaminated with the faeces of an infected person or carrier.
Poor sanitation, unsafe drinking water and inadequate hand hygiene can increase the risk of transmission.
Unlike malaria, typhoid is not transmitted through mosquito bites.
Malaria vs. Typhoid: The Major Differences
Although both illnesses can cause fever and weakness, several important differences can help distinguish them.
1. They Are Caused by Different Organisms
Malaria is caused by a parasite belonging to the Plasmodium group. Typhoid fever is caused by the bacterium Salmonella Typhi. This difference is important because the medicines used to treat the two infections are different.
2. They Spread in Different Ways
Malaria is primarily transmitted through the bite of an infected female Anopheles mosquito. Typhoid is generally spread through contaminated food and water or through poor hand hygiene that allows the bacteria to enter the mouth.
Therefore, preventing malaria involves measures such as reducing mosquito exposure, while preventing typhoid requires attention to safe water, food hygiene, sanitation and handwashing.
3. Fever Can Present Differently
Fever is common in both malaria and typhoid. Malaria can cause episodes of fever that may occur with chills, sweating and headache. The pattern can vary depending on the malaria parasite involved and the individual.
Typhoid fever can cause a persistent fever that gradually becomes higher over several days. However, fever patterns alone cannot reliably tell you whether you have malaria or typhoid.
4. Digestive Symptoms May Be More Prominent With Typhoid
Typhoid can cause abdominal pain, nausea, loss of appetite and changes in bowel movements. Some people develop diarrhoea, while others may become constipated. Vomiting can also occur.
Malaria can also cause nausea, vomiting and abdominal discomfort, particularly in children, so digestive symptoms do not automatically mean typhoid.
5. Malaria Can Cause Chills and Sweating
A person experiencing malaria may develop episodes of chills followed by fever and sweating. The combination can be particularly uncomfortable and may leave the person feeling weak and exhausted.
However, not everyone with malaria experiences the classic cycle of chills, fever and sweating. This is another reason why symptoms alone are not sufficient for diagnosis.
6. Malaria Can Become Severe Quickly
Severe malaria can affect the brain, kidneys, lungs and other organs. Warning signs can include confusion, seizures, difficulty breathing, severe weakness, loss of consciousness, severe anaemia or other signs of organ dysfunction. Severe malaria requires urgent medical treatment.
7. Typhoid Can Cause Serious Intestinal Complications
Untreated typhoid fever can cause serious complications. In severe cases, the infection can damage the intestines and lead to intestinal bleeding or perforation. It can also affect other organs.
This is why persistent fever and other symptoms should be medically assessed rather than repeatedly treated at home.

Can You Have Malaria and Typhoid at the Same Time?
Yes, it is possible for a person to have malaria and typhoid fever at the same time. However, having a fever does not automatically mean that both infections are present.
Because malaria and typhoid occur in areas where their risk factors can overlap, a person may genuinely have both infections. But it is important to establish the diagnosis rather than assuming that every unexplained fever is “malaria and typhoid.”
Why Symptoms Are Not Enough to Tell the Difference
Both conditions can cause fever, headache, weakness, loss of appetite, nausea and general body discomfort.
Other illnesses can cause similar symptoms as well. Viral infections, urinary tract infections, respiratory infections and several other conditions can produce fever and weakness.
This means that taking malaria or typhoid medicines simply because you have a fever may result in the wrong treatment.
How Is Malaria Diagnosed?
Malaria can be diagnosed by testing a blood sample for malaria parasites. Depending on the healthcare setting, this may involve microscopy or a malaria rapid diagnostic test.
Testing is important because the symptoms of malaria can resemble those of other illnesses.
How Is Typhoid Diagnosed?
Typhoid diagnosis can be more complicated because several tests are available, but they do not all have the same reliability. Blood culture is an important laboratory method for confirming typhoid fever because it can identify Salmonella Typhi in the blood.
Some commonly used tests, including the Widal test, can be difficult to interpret and may produce misleading results, particularly in areas where exposure to related bacteria or previous infections is common.
A healthcare professional should determine which test is appropriate based on the person’s symptoms, history and available laboratory facilities.
How Are Malaria and Typhoid Treated?
Malaria is treated with antimalarial medicines appropriate for the specific malaria infection and local treatment guidelines.
Typhoid fever is treated with appropriate antibiotics. However, antibiotic resistance has become an important concern, making it increasingly important that treatment is guided by healthcare professionals and, where appropriate, laboratory testing.
Taking antibiotics without a confirmed or well-supported diagnosis can contribute to antibiotic resistance and may expose you to unnecessary side effects.
Why You Should Not Self-Medicate
A common mistake is to develop a fever and immediately take several medicines for “malaria and typhoid.”
This can be problematic for several reasons. You may not have either infection, the medicine may be inappropriate, or the infection may require a different treatment.
Unnecessary antibiotics are particularly concerning because bacteria can develop resistance, making future infections harder to treat.
If you have a persistent or unexplained fever, it is safer to seek medical assessment and appropriate testing.
How Can Malaria Be Prevented?
Sleeping under insecticide-treated mosquito nets, reducing mosquito breeding sites around homes and using appropriate mosquito-control measures can reduce exposure.
People should also seek prompt medical attention when malaria is suspected, particularly when symptoms are severe or occur in vulnerable individuals such as young children and pregnant women.
How Can Typhoid Be Prevented?
Typhoid prevention depends heavily on safe water, food hygiene and sanitation. Drink water from a safe source and practise good hand hygiene, particularly after using the toilet and before preparing or eating food.
Food should be properly cooked and stored safely. Fruits and vegetables should be washed appropriately, and people should be cautious about consuming food or drinks from sources where hygiene standards are uncertain.
Typhoid vaccination is also an important prevention option in appropriate settings.
When Should You See a Doctor?
You should seek medical attention if you develop a persistent fever, particularly when it is accompanied by severe weakness, repeated vomiting, abdominal pain, confusion, difficulty breathing or other concerning symptoms.
Children, pregnant women, older adults and people with certain underlying health conditions may require particular attention when they develop a significant fever.
Do not wait for symptoms to become severe before seeking care if you are concerned about malaria or typhoid.
Final Thoughts
Malaria and typhoid are different diseases, even though they can cause some similar symptoms.
Malaria is caused by a parasite and is mainly transmitted through infected mosquito bites. Typhoid is a bacterial infection that is generally spread through contaminated food and water.
The biggest mistake is to assume that every fever is malaria, typhoid or both. Proper testing and medical assessment can help identify the actual cause and ensure that the person receives the appropriate treatment.
