Overview

Did you know that pertussis, also known as whooping cough, can cause children to miss weeks of school? This highly contagious respiratory disease is notorious for severe coughing fits that can last up to ten weeks or more, making it a significant cause of prolonged school absenteeism.¹

Understanding pertussis

Pertussis, commonly known as whooping cough, is a highly contagious bacterial infection of the respiratory tract caused by the bacterium Bordetella pertussis.¹ This pathogen releases toxins that damage the respiratory tract and cause inflammation, leading to the characteristic severe coughing spells.²

Pertussis progresses through three distinct stages, each with its own set of symptoms:³

1. Catarrhal stage (1-2 weeks): This initial phase resembles a common cold, with symptoms such as a runny nose, mild fever, and occasional cough.⁴ Because these early symptoms are nonspecific, pertussis is often misdiagnosed during this stage, allowing the bacteria to spread unnoticed
2. Paroxysmal stage (1-6 weeks): The hallmarks of pertussis appear in this stage with severe, uncontrollable coughing fits, or paroxysms.¹ These coughing episodes can be so intense that they cause vomiting, exhaustion, and the characteristic "whooping" sound as the person inhales deeply after a coughing spell
3. Convalescent stage (2-3 weeks): This is the recovery phase, during which coughing spells gradually decrease in frequency and severity.^1,4 However, it may take several weeks to months for the person to fully recover and regain normal respiratory function⁵

Pertussis spreads primarily through respiratory droplets when an infected person coughs or sneezes.¹ It is highly contagious, especially in the early stages of the disease. Close contact with an infected person, such as in schools or households, significantly increases the risk of transmission.

Pertussis and school-age children

Why children are particularly vulnerable

School-age children are especially susceptible to pertussis due to their close contact with peers in classrooms, playgrounds, and other group settings. Because pertussis is highly contagious, once one child is infected, the bacteria can spread quickly through coughing or sneezing. 

Vaccination is the most effective tool for preventing pertussis. The DTaP vaccine (diphtheria, tetanus, and acellular pertussis) is administered to children in a series of shots beginning at two months of age, with boosters given throughout childhood.⁶ For older children and adults, the Tdap booster helps maintain immunity.⁶

Despite the availability of vaccines, pertussis outbreaks can still occur, emphasizing the importance of maintaining high vaccination coverage and adhering to booster schedules to ensure continued immunity.⁷ 

How pertussis leads to school absenteeism

1. Severity and duration of illness: Pertussis significantly impacts school attendance due to its severe and prolonged symptoms. The illness starts with cold-like symptoms but quickly escalates into intense coughing fits that can last for weeks or even months. These coughing spells can cause vomiting, exhaustion, and difficulty breathing, making it nearly impossible for affected children to participate in regular school activities
2. Recovery time and post-illness fatigue: Even after the most severe symptoms have subsided, recovery from pertussis is often slow. Children may continue to experience fatigue, weakness, and residual coughing for several weeks, further delaying their return to school⁸
3. Need for quarantine and preventing the spread: Due to the highly contagious nature of pertussis, children diagnosed with the disease are often required to stay home to prevent spreading it to classmates and school staff. Quarantine measures are essential for controlling outbreaks, especially in school environments where close contact is common. However, this necessary precaution contributes to increased absenteeism

Pertussis outbreaks can lead to significant spikes in absenteeism rates. These high rates of absenteeism not only disrupt individual learning but also place a strain on school resources, as administrators and teachers work to manage the situation and support affected students.

Broader effects of absenteeism due to pertussis

Academic impact on affected students

1. Missed instructional time: When students contract pertussis, they can be out of school for several weeks. This extended absence means they miss a substantial amount of instructional time. Unlike other illnesses that may require only a few days of recovery, pertussis can lead to prolonged absenteeism, making it difficult for students to keep up with the curriculum. The longer they are away from the classroom, the more challenging it becomes to stay on track with their studies. This missed time can create gaps in knowledge, particularly in subjects that require continuous learning and practice, such as math and language arts
2. Challenges in catching up with schoolwork: Returning to school after a lengthy illness can be daunting for students. They may feel overwhelmed by the amount of schoolwork they need to catch up on. Teachers often have to spend extra time providing remedial instruction to help these students understand the missed material. Additionally, students may need to balance catching up on past lessons with keeping up with current assignments, leading to increased stress and pressure. This dual burden can negatively impact their overall academic performance and enthusiasm for learning

Emotional and social consequences

1. Isolation from peers: One of the less visible but equally significant effects of pertussis-related absenteeism is the social isolation it can cause. School is not just a place for academic learning; it is also where children develop social skills and build friendships. Being away from this environment can make students feel isolated and disconnected from their peers. Missing out on social interactions and extracurricular activities can lead to feelings of loneliness and exclusion, which can negatively impact their emotional well-being
2. Stress and anxiety related to illness and missed school: The stress of dealing with a serious illness like pertussis, combined with the anxiety of missing school and falling behind, can be overwhelming for students. They may worry about catching up academically and fitting back in with their classmates. The fear of returning to school after a long absence, along with the potential stigma associated with being ill, can exacerbate these feelings. This stress and anxiety can manifest in various ways, including trouble sleeping, lack of concentration, and a general sense of unease

Impact on families

1. Parental work absenteeism: When a child is ill with pertussis, it is not just the student who is affected. Parents often need to take time off work to care for their sick child, leading to work absenteeism. This can be particularly challenging for families with limited leave options or those in jobs without paid sick leave. The need for parental presence at home to provide care and support can disrupt the family’s routine and add to the stress of managing household responsibilities
2. Financial implications of medical care and missed work: The financial impact of pertussis on families can be significant. Medical expenses for doctor visits, medications, and potential hospitalizations can quickly add up. Additionally, when parents miss work, it can lead to lost income, which can be especially burdensome for families already facing financial challenges. The combination of increased medical costs and reduced income can create financial strain, affecting the family’s overall well-being

FAQs

How long can a child with pertussis be absent from school?

Children with pertussis may be absent from school for up to three weeks or longer, depending on the severity of their symptoms and their recovery rate. They are often required to stay home until they have completed a course of antibiotics and are no longer contagious.

What measures can schools take to prevent the spread of pertussis?

Schools can promote vaccination against pertussis, encourage good hygiene practices such as regular hand washing, and implement policies for staying home when sick. Educating parents and staff about the signs and symptoms of pertussis can also aid in early detection and the prevention of outbreaks.

How can parents help their child catch up academically after recovering from pertussis?

Parents can work with teachers to develop a plan for catching up on missed schoolwork. This might include additional tutoring, modified assignments, or extra study time. Encouraging a structured routine at home and maintaining regular communication with the school can also support the child's academic recovery.

What should parents do if they suspect their child has pertussis?

If pertussis is suspected, parents should contact their healthcare provider immediately. Early diagnosis and treatment with antibiotics can help reduce the severity of symptoms and prevent the spread of the infection to others. Parents should also keep their child home from school and other public places until the child is no longer contagious.

Summary
