Introduction
Typhoid fever is a significantly contagious bacterial infection, typically prevalent in regions with inadequate water quality and sanitation. Transmission can occur through contaminated food or water and direct contact with an infected individual. Common symptoms encompass an escalating fever, abdominal discomfort, headaches, fatigue, muscle pain, constipation, diarrhea, or a rose-colored rash. Timely administration of antibiotics is essential for effective treatment, as untreated typhoid poses a serious threat to life. Mitigating the risk of infection involves receiving the typhoid vaccine and adhering to proper hygiene practices.
What Is Typhoid Fever?
Typhoid fever, also known as enteric fever, is a bacterial infection caused by salmonella typhi, a specific strain of bacteria residing in the intestines of infected individuals. Although salmonella typhi differs from the bacteria responsible for salmonella food poisoning, they share a connection. Once these bacteria enter the body, they rapidly multiply in the digestive system and intestines, leading to symptoms like a high fever, stomach ache, and digestive issues such as diarrhea or constipation.
Without prompt treatment, the bacteria can extend from the intestines into the bloodstream, affecting various organs and parts of the body. Untreated symptoms can worsen, lasting for four weeks or more, and may result in severe complications. These complications include a potentially life-threatening infection caused by the perforation of the bowel, sepsis or septic shock, and internal bleeding (hemorrhage).
Although less frequent, typhoid fever can also give rise to additional complications such as pneumonia, meningitis, inflammation of the heart muscle or valves, pancreas inflammation, infections in blood vessels, bladder, or kidneys, as well as hallucinations and delirium.
How Does Typhoid Infection Spread?
Typhoid is highly contagious and typically spreads when an infected person neglects proper hand hygiene, particularly after using the toilet. The germs can linger on their hands, transferring to others and contaminating surfaces they touch. The following are common ways through which typhoid spreads:
1. Consuming Contaminated Food or Water:
-
Eating food that has been near contaminated water or drinking unclean water, often due to poor sanitation and insufficient food hygiene practices.
-
Washing food items and ingredients or producing them with unclean water leads to contamination with bacteria from the infected person's urine or feces.
2. Hand-to-Mouth Transmission: Transmission occurs when a person uses a contaminated toilet and fails to practice proper hand hygiene, spreading germs through hand-to-mouth contact.
3. Environmental Factors:
-
Poor water quality, inadequate sewage disposal, and flooding can cause the contamination of water supplies with infected human waste.
-
In areas with high water quality and widespread availability of chlorinated water, transmission is more likely through contaminated food handled by infected individuals.
4. Consuming Raw or Contaminated Items:
-
Consumption of raw fruits and vegetables cultivated in fields irrigated with sewage water and fertilizer.
-
Raw milk, contaminated products, flavored drinks, and ice creams can carry salmonella typhi and paratyphi.
-
Shellfish Contamination: In some countries, shellfish taken from sewage-contaminated beds serve as a significant route of infection.
-
Sexual Transmission: Engaging in anal or oral sex with a person carrying salmonella typhi bacteria can contribute to the spread of the infection.
What Are the Symptoms of Typhoid in Pregnancy?
Typhoid presents a range of signs and symptoms, which differ from mild to severe, typically emerging one to three weeks or more after consuming contaminated food or drink.
Common symptoms of typhoid include:
-
Persistent high fever, worsening in the evenings and improving in the morning, progressively increasing daily.
-
Headache.
-
Loss of appetite.
-
Aches and pains, particularly abdominal pain.
-
Diarrhea, although some individuals may experience constipation instead.
-
Slow heart rate.
-
Weakness.
-
Extreme fatigue.
-
Nausea and vomiting.
-
Chills.
-
Confusion.
Additional signs of typhoid may include:
-
Rose-colored rash or faint pink spots are often observed on the neck, chest, or stomach (present in some individuals).
-
Weight loss.
-
Enlarged spleen and liver.
These symptoms can resemble those of other feverish illnesses like dengue or malaria, making it challenging to diagnose typhoid based solely on symptoms. It is advisable to consult a healthcare professional for accurate diagnosis and appropriate management, especially during pregnancy.
Can Typhoid Harm Pregnancy or Baby?
-
Typhoid is a serious illness that can lead to significant health complications if not treated promptly, and in severe cases, it can even be fatal.
-
Typhoid has the potential to cross the placenta, causing infection and increasing the risk of miscarriage.
-
Water-borne infections, including typhoid, may elevate the chances of premature birth, low birth weight, or having a baby that is small for gestational age.
However, it is essential to emphasize that with timely identification and appropriate medical care, it is still possible to experience a healthy pregnancy and deliver a robust baby. If someone experiences any symptoms or suspects a possible infection, it is essential to inform the doctor for appropriate medical attention and care promptly.
What Is the Diagnosis of Typhoid in Pregnancy?
Diagnosing typhoid fever during pregnancy typically relies on more than just observing symptoms. A crucial diagnostic method is a blood culture, a laboratory test that examines a blood sample for the presence of bacteria. Another blood test, the Widal test, is used to diagnose typhoid, although its specificity and sensitivity may be limited. Additionally, the urine and stools of an infected individual may be examined for the presence of bacteria.
A bone marrow test may be conducted, although this is rare. Other laboratory assessments include a hemoglobin test to check for anemia and liver function tests. The doctor will recommend specific tests based on the individual condition. Once typhoid is confirmed, the doctor may advise testing other family members to ensure that the infection has not spread to them.
What Is the Treatment of Typhoid in Pregnancy?
The treatment for typhoid in pregnancy involves the use of antibiotics. However, there are concerns regarding the resistance of typhoid to certain antibiotics. When treatment is initiated within the initial days of the illness, particularly in its early stages, symptoms are likely to be mild and typically improve within about two days of starting treatment. Noticeable improvement in the condition should occur four or five days into the treatment. Serious complications are very uncommon when treatment is administered promptly.
Delaying the initiation of treatment can prolong the recovery period and heighten the risk of complications. Consequently, the doctor may start the antibiotic course before testing results once typhoid is suspected. If typhoid is confirmed, the doctor may decide to adjust the specific type of antibiotic prescribed.
In more severe instances of typhoid fever, hospital admission may be necessary to administer antibiotic injections and closely monitor the patient's condition. If severe dehydration is evident, the doctor may recommend intravenous fluid administration. It is important to note that complete recovery may take weeks or even months, and without proper treatment, symptoms may reoccur.
Conclusion
In conclusion, typhoid fever poses serious health risks, especially during pregnancy. Early diagnosis through blood tests, such as blood cultures and the Widal test, is crucial. Quick treatment with antibiotics is essential to cure severe complications and potential harm to the baby. Timely initiation of treatment, even before receiving test results, is recommended to expedite recovery. Hospitalization may be necessary for severe cases, with additional measures like intravenous fluid administration for dehydration. Complete recovery may take weeks or months, emphasizing the importance of proper and timely medical intervention.
