Malaria Effect on Host

by

QUESTION

What is the effect of malaria on host?

ANSWER

In the human host, malaria can often make a person very sick, though the exact symptoms and severity of the disease depends on the type of malaria (five different kinds of malaria infect humans). Many people will have a high fever, chills, nausea and body aches. In a symptom very typical of malaria, a patient will experience cyclical fever, with periods of no fever in between, lasting between one and two days. In infections with Plasmodium falciparum, the most dangerous kind of malaria, patients may experience impaired consciousness, a sign of “cerebral malaria”, which can lead to loss of consciousness, coma and even death.

In terms of the mosquito host (more commonly called the vector), the insect does not experience “illness” in the same way as the human host, and the parasite does not seem to have a particularly negative effect on the mosquito. However, some research has shown that infection with malaria may cause a mosquito to seek out blood meals more frequently, which scientists argue is an adaptation of the malaria parasite to ensure that its life cycle is continued.

Swelling of Lymph Nodes and Malaria

QUESTION

I would like to know if swelling of lymph nodes in neck is any way connect to malaria?

ANSWER

Swollen lymph nodes are often a sign that the body is trying to fight off an infection, and so swollen lymph nodes are certainly sometimes observed in malaria patients. However, most malaria infections would also be associated with other symptoms, such as fever, chills, nausea and aches.

In some cases (but not all), malaria patients experience cyclical fever, whereby they have a high fever one day and no fever the next, but the fever returns on the third day, and the cycle continues. One type of malaria exhibits a cycle of fever one day, then no fever for two days, then fever returns on the fourth day. However, many patients do not experience these cycles, which means their symptoms are very similar to those for many other illnesses, which is why if you are in or have been visiting an area where malaria is transmitted and you have some of the above symptoms, it is very important to visit a doctor or clinic to get diagnosed for malaria. This can be done with a simple blood test, and the results are usually available very quickly. Then, if you are diagnosed as positive for malaria, the doctor can recommend appropriate treatment and instruct you in the proper way of taking it.

Symtoms of Malaria

QUESTION

Please tell me the symptoms of malaria.

ANSWER

Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Due to the way in which the malaria parasite reproduces in the human body, fevers occurring in a cyclical fashion (i.e. high fever one day, no fever the next day, then recurrence of fever on the third or fourth day, depending on the type of malaria) are a characteristic symptom of malaria, but may not be present in all cases. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells. Symptoms usually appear between 10 and 15 days after the mosquito bite. If not treated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs. When blood supply to the brain is disrupted during malarial infection, the resulting condition, characterised by seizures, mental confusion, coma, and death, is known as “cerebral malaria”, and is associated with Plasmodium falciparum, the most deadly form of malaria.

ANSWER

Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells.

Symptoms usually appear between 10 and 15 days after the mosquito bite. If not treated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs. Infection with one type of malaria, Plasmodium falciparum, if not promptly treated, may cause kidney failure, seizures, mental confusion, coma, and death. In many parts of the world, the parasites have developed resistance to a number of malaria medicines.

Cyclical Fever and Malaria Symptoms

QUESTION

My dad is not well from last one month. In the evening time he feels headache, neck pain and 102 Temp.

Can you please tell me can it be Malaria.

ANSWER

Those symptoms can be characteristic of malaria—cyclical fever is a key symptom, though usually the cycles are every other day or even every third day (depending on the type of malaria). However, in some cases the cycles are more frequent or the patient may even have constant fever.

One of the difficulties with diagnosing malaria is that its symptoms are very general and can therefore be mistaken for many other illnesses. Likewise, in areas of high malaria transmission, doctors may assume a feverish illness is malaria without thinking about other possible diseases. As such, it is crucial that you take your father for a blood test, which is the only accurate way to diagnose malaria.

The doctor or clinician will either make a blood film and look at it under the microscope, or use a tiny drop of blood in a rapid diagnostic test. Either way, it is important for them to see evidence of a malaria infection before they give your father treatment. The diagnostic test should also show which type of malaria your father has (if indeed he has malaria), and this will also help to determine which is the most appropriate type of medication.

ANSWER

Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells.

Symptoms usually appear between 10 and 15 days after the mosquito bite. If not treated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs. Infection with one type of malaria, Plasmodium falciparum, if not promptly treated, may cause kidney failure, seizures, mental confusion, coma, and death. In many parts of the world, the parasites have developed resistance to a number of malaria medicines.

For most people, symptoms begin 10 days to 4 weeks after infection, although a person may feel ill as early as 7 days or as late as 1 year later. Two kinds of malaria, P. vivax and P. ovale, can occur again (relapsing malaria). In P. vivax and P. ovale infections, some parasites can remain dormant in the liver for several months up to about 4 years after a person is bitten by an infected mosquito. When these parasites come out of hibernation and begin invading red blood cells (“relapse”), the person will become sick.

Infection with malaria parasites may result in a wide variety of symptoms, ranging from absent or very mild symptoms to severe disease and even death. Malaria disease can be categorized as uncomplicated or severe (complicated) . In general, malaria is a curable disease if diagnosed and treated promptly and correctly.

Cyclical Fever

QUESTION

My husband has been suffering from recurring fever every 3rd or 4th day for the past 7 months. All blood tests are normal, esr ,crp, cultures of urine and blood all normal, chest ct full body pet heart echo all normal. Tested positive for montoux and quantiferon gold, with no symptom other than fever, was put on ATT on 4th JULY 2011 fever persists with no other symptoms. Has been on ATT for more than 4 months with no respite and as per doctor TB is ruled out but 6 month course mandatory. Please help. Fever comes with mild chills and head ache at times.

ANSWER

Cyclical fever every few days is one of the characteristic signs of malaria, and the length of the cycles can help identify the type of malaria. Specifically a fever every three days is indicative of Plasmodium malariae infection, which also fits with the long, chronic persistence of the illness.

This parasite can be hard to diagnose as it is often present in low concentrations in the blood. If you haven’t had a blood film done already, ask your doctor to make a thin and thick blood film to look for the presence of Plasmodium malariae in your husband’s blood.

If the first films are negative, continue with daily films for a further 2 or 3 days. Another diagnostic option is a rapid diagnostic test, which can detect antibodies to the malaria parasites in the blood. P. malariae is easily treated with chloroquine.

Unfortunately, without further information and a more complete medical history it will be impossible to make a further diagnosis of your husband’s condition, but certainly checking for Plasmodium through a blood test would be a good first step.
