When you are expecting, worries about influenza (the flu) are likely to become sharper than usual, but the most important thing here is to know that you can safeguard yourself and your unborn baby, and how one can do so. Proper care and knowledge of how to bypass this flu season with the maximum possible precautions are a must, not only for you but also for the little life inside.

Even in the case of mild flu, pregnant people are at more risk from the complications of flu. 

Get more information on managing flu during your pregnancy, including safe medications and other steps you can take to protect your health and that of your baby.

How Influenza Impacts Pregnancy

Influenza during pregnancy carries marked risks due to physiological changes that may not fully support the immune system in a person who is expecting. It hence may predispose the person to developing severe complications related to the respiratory system. Here is an elaboration of these risks:

Early labour and delivery 

The flu is associated with an increased risk for early labour and preterm birth, perhaps due to the physical stress and inflammation the virus provokes.

Symptomatic management 

The fever, which is very often concomitant with influenza, is something that becomes of great importance during gestation. Fever has been correlated with complications in the development of the foetus. Hence, it is advised to use acetaminophen (paracetamol) for the safe treatment of fever during gestation.¹

Safety and Effectiveness of the Flu Vaccine

Influenza vaccination has been found to offer good protection against the disease during any trimester of pregnancy and its safety and effectiveness are well-researched.

Safety

Research has shown that the flu vaccine is safe in all three trimesters of pregnancy and causes only a few mild side effects, such as soreness at the injection site or a low fever.

Efficacy 

The flu vaccine can cut the risk of getting flu or a flu-related acute respiratory infection in half. Vaccinations during pregnancy also help the baby to develop passive immunity to the flue. The antibodies given by the pregnant parent to their foetus protect the baby against the flu for several months after being born but before being able to be vaccinated.

Planning beyond vaccination

While vaccination is an excellent preventive effort, these additional preventive efforts are equally important in reducing exposure to the minimum and improving health in general:

Avoid crowds

Avoid spending unnecessary time around crowds during the worst times for the flu.

Healthy lifestyle 

The pregnant parent should try their best to have a nutritious diet, including many fruits, vegetables, and proteins. Proper hydration helps maintain a healthy immune system. Ensuring adequate intake of vitamins C and D can boost immune function too.

Moderate regular exercises during pregnancy can help to build a more robust immune system and better respiratory health.

Treatment Options During Pregnancy

Early treatment can be vital in a pregnant person's case if they catch the flu.

Antiviral drugs

Neuraminidase inhibitors, such as oseltamivir (Tamiflu), are recommended for pregnant people who test positive for the flu. This is especially effective when given within 48 hours of developing flu symptoms.

Consult and monitor

Pregnant people with flu-like symptoms should consult and monitor with their health provider from time to time to avoid further complications in the body that might develop during pregnancy.²

When to seek medical attention

It's important that you know when to seek emergency medical attention to avoid severe problems. Symptoms that signal you should visit emergency medical services immediately include:

• Trouble breathing
• Constant pressure or pain in the chest
• Constant dizziness
• Severe or heavy vomiting
• Very high fevers that do not come down after taking fever-reducing medicines

Look out for the following warning signs of emergencies and promptly seek the attention of a doctor: 

• increasing or new onset of symptoms and decreased foetal movements 

Emergency treatments can largely mitigate the health risks to the pregnant parent and baby if received in a timely manner. They can also help to promote a safe pregnancy and delivery process.

Effectively managing influenza during pregnancy is critical not only for the health of the expectant parent but also for the safety and well-being of the unborn child. Management involves a combination of preventative measures, timely treatment, and vigilant monitoring of symptoms. Here’s a detailed breakdown:

Vaccination 

Receiving the seasonal flu vaccine is the cornerstone of flu prevention. It's recommended for all pregnant people and can be administered during any trimester. The vaccine is specifically designed to protect against the strains of flu that are expected to be most common during the upcoming season.

Hygiene practices 

Maintaining excellent hygiene is crucial. This includes frequent handwashing with soap and water, using hand sanitiser when soap and hot water are not available, avoiding touching the face, and practising good respiratory hygiene by covering coughs and sneezes with a tissue or the elbow.

Environmental controls 

Reducing exposure to the flu virus by avoiding crowded places during peak flu season and staying away from people who are sick can significantly decrease the risk of contracting influenza.

Early Treatment of Influenza in Pregnancy

Early treatment of influenza in pregnancy is essential in reducing adverse outcomes. This includes timely administration of antiviral medications that can significantly change the severity of the illness.²

Role of antiviral medications

Antiviral medicines work in such a manner as to block the life cycle of flu viruses in the body; hence, they lessen the symptoms and length of illness. This proves very helpful in preventing severe complications that might harm both the pregnant parent and baby.

Timing of treatment

Antiviral treatment has the best effect when it is begun within two days after the onset of illness. Early intervention is essential for better control over symptoms and shortening the course of the disease. Expectant parents should seek prompt medical care if they develop any signs of disease, such as fever, cough, sore throat, body aches, or extreme tiredness, and begin treatment with antiviral medications as soon as possible.

Consultation and prescription

If they are experiencing such flu-like symptoms, a pregnant person should consult a healthcare provider immediately. The provider may prescribe an antiviral drug, usually oseltamivir or zanamivir, based on clinical evaluation. This is considered safe and effective for pregnant people.

Regular Monitoring

Regular, consistent monitoring throughout the pregnancy is critical if one has been exposed to or is symptomatic of influenza.

Importance of prenatal checkups

These enable insight into the expectant parent's health and the way their body responds to pregnancy, including the development of the foetus. Most important during the flu season is the possibility of its effects on the expectant parent and their pregnancy.

During illness, monitoring may have to be stepped up. If a pregnant person contracts the flu, monitoring may need to be enhanced. This could include an increase in monitoring of the baby's activity or more tests, such as ultrasounds, to make sure the pregnancy is going as it should.

For expectant parent, tracking these symptoms is important and if there is a noticeable change in their health status this should be reported immediately to their health provider. This is in an attempt to manage the symptoms before any complications such as dehydration and high fever.

Education

Pregnant people need to receive education on how to prevent flu and early treatment. Education will empower them to take charge of their health decisions and take the initiative to seek medical attention early when required.

By emphasising the importance of prompt medical responses to influenza symptoms and ensuring regular health monitoring, pregnant people can better manage their health during flu season. This proactive approach helps safeguard the wellbeing of both the pregnant parent and their unborn child, reducing the risk of flu-related complications and promoting a healthy pregnancy.

By adhering to these strategies, pregnant people can mitigate the impact of influenza and protect themselves and their babies from serious health issues.

Frequently Asked Questions

Can the flu vaccine cause the flu?

No, the flu vaccine can't give a person the flu. It only contains one protein from a flu virus: either killed-inactivated viruses or just one protein, which couldn't make a person infected by it. The body’s immune response to the vaccine strengthens the immune system to fight off the actual virus if encountered.

What are the signs that I should seek immediate medical attention?

Severe symptoms that may need immediate medical attention include difficulties in breathing, persistence of or severe chest pain, sudden dizziness, or confusion. Less common symptoms include those that may improve but later come back more severe than before, for example, less or no movement of the baby and high fever not controlled by drugs like Acetaminophen. These symptoms could indicate severe complications that require urgent care.

However, all these risks can be effectively managed in pregnant women through proactive prevention, vigilant symptom monitoring, and prompt treatment against influenza.

Summary

Influenza commonly spreads in the general population around the winter period each year, leading to significant illness and mortality. However, contracting “the flu” can be particularly risky for pregnant people, who may become more susceptible to negative maternal and infant health outcomes such as preterm labour and complications with delivery when infected with influenza. Preventative measures, especially uptake of the flu vaccine, are essential in preventing flu and its complications in pregnant people. Where they do become infected, effective treatment and management of the flu such as through antiviral medications and increased medical monitoring and the expectant parent’s and infant’s health status, can decrease the risk of dangerous negative health outcomes.
