Medical specialists in Portugal are raising alarms over a critical but often overlooked manifestation of the Human Papillomavirus (HPV): the development of respiratory papillomatosis in children. The Unidade da Voz (Voice Unit) at the Hospital Egas Moniz has highlighted a distressing trend where infants are contracting the virus during childbirth, leading to severe airway obstructions that, in the most acute cases, necessitate a traqueostomia to ensure the child can breathe.
The condition occurs when a newborn aspirates the virus while passing through the birth canal of an infected mother. According to Clara Capucho, an otorhinolaryngologist and pioneer in voice studies in Portugal, this vertical transmission is a significant “focus of concern.” The virus can settle in the larynx, growing into cauliflower-like masses known as papillomas that can gradually close off the respiratory tract.
This health crisis is disproportionately affecting specific vulnerable populations. Capucho notes that many cases are seen in children of immigrant women from Latin America, Cabo Verde and Angola who may not have had access to the HPV vaccine prior to pregnancy, particularly when delivering via vaginal birth.
The Path from Birth to Surgical Intervention
For affected children, the onset of symptoms often occurs within the first few years of life. As the papillomas grow in the larynx, they don’t just threaten the child’s ability to speak; they create a life-threatening blockage of the airway. In these “dramatic circumstances,” surgeons must perform a traqueostomia—creating an opening in the neck—to bypass the obstruction.
The recovery process is rarely swift. While some children may eventually suppress the virus through their own immune response, many face a “long road” of repeated surgeries and lifelong monitoring. Capucho describes patients who entered the clinic at age four and are still under tight surveillance at ages 12 and 13. Even after the traqueostomia is removed and the voice returns to normal, the risk remains because the virus persists in the body.
The clinical challenge lies in the fact that there is no definitive “cure” for the virus itself; medical intervention can remove the physical growths, but the body’s own immune system must ultimately suppress the viral activity to prevent recurrence.
A Rising Trend in Adult Laryngeal HPV
The concern is not limited to pediatric cases. The Unidade da Voz has observed a significant increase in HPV within the adult population during its annual screenings. This surge is attributed to a combination of evolving sexual habits and the effects of globalization, which has increased the movement of people from regions where these pathologies are more prevalent.
Unlike some other viral infections, HPV in the larynx is not entirely benign. While the resulting papillomas are often benign growths, they can obstruct breathing and permanently alter the voice. More critically, the multiplication of the virus is closely linked to the development of malignant tumors, including laryngeal cancer.
Recent data from the unit’s screenings underscore the prevalence of laryngeal distress. In a sample of 120 individuals evaluated last year, the findings revealed a complex interplay of respiratory risks:
| Condition Identified | Prevalence/Percentage | Clinical Significance |
|---|---|---|
| HPV Presence | 21% | Risk of papillomas and potential malignancy |
| Leukoplasias | 7% | White mucosal lesions; potentially malignant |
| Acid Reflux | 60% | Caustic effect; may contribute to carcinoma |
The Role of Vaccination and Early Detection
Public health experts emphasize that the most effective defense against this trajectory is the National Vaccination Program. While the HPV vaccine is now recommended for both boys and girls, Capucho warns that a “later population”—those who missed the initial rollout—remains unprotected and vulnerable.

There is also a growing concern regarding the general resilience of the human immune system. Capucho suggests that following recent global pandemics, the human body may have become “more sensitive” to viral threats, making the proactive management of HPV even more urgent.
To combat this, the Unidade da Voz, founded in 2005, focuses on early diagnosis. By using direct observation of the vocal cords and analyzing patient habits, the unit aims to identify pathologies when they are still reversible, thereby minimizing the demand for invasive “mutilation” or permanent surgical alterations.

In observance of World Voice Day, the Unidade da Voz at Hospital Egas Moniz, supported by the GDA Foundation, continues to offer free screenings to the public to promote early detection and laryngeal health.
