Those affected by this disorder that is transmitted by the bite of an infected tick demand attention for “a forgotten problem”

It’s been more than 10 years, but Rocio Muñoz He remembers it like it was yesterday. That rash that her daughter Carla got on her foot during the holidays seemed like a target. With a red dot in the center and a ring around it. “It was no bigger than a two-euro coin and I hadn’t noticed any bite nor did it bother him, so we didn’t give it any more importance,” she remembers. “Unfortunately, then we did not know that this was the first sign of a terrible disorder that was going to change our lives.” Muñoz pronounces it bitterly: Lyme’s desease.

It took more than five years to name the cascade of symptoms that appeared and that still affect Carla’s health today, who “has serious neurological problems and has no sensitivity in part of her legs.” Because the disease, which is also known as “the great imitator”camouflages its many faces and is often confused with other disorders, such as fibromyalgia, chronic fatigue, rheumatoid arthritis, multiple sclerosis…

Like Muñoz, Naiara Olague He also claims to have lived a “true pilgrimage” in search of a diagnosis that would explain the neurological, ophthalmological and cardiac problems that he began to suffer in 2016. “I did not find the key until 2018 and because I insisted and moved because the doctors did not think in this disease. “They even suggested that I make an appointment in Psychiatry,” laments this 39-year-old Navarrese publicist who, together with Muñoz and other affected people, denounced this week in the Senate. the invisibility of Lyme disease in Spain.

“We need to take measures against this silent epidemic,” they claim. “This can happen to anyone and actions are needed to prevent it and diagnose it better now.”

This multisystem disorder is caused by infection with bacteria of the genus Borrelia that are transmitted through the bite of a tick – mainly Ixodes ricinus in our midst. In Europe it is considered an emerging disease. And, in fact, in 2018 the European Center for Disease Prevention and Control (ECDC) included the neuroborreliosis, one of the main complications associated with Lyme disease, on the list of disorders to especially monitor. However, there is no accurate data on its incidence, especially in some countries on the continent, such as Spain.

confirms it Rosa Estevezresponsible for the epidemiological surveillance of zoonotic diseases at the National Epidemiology Center: «There is still no national surveillance protocol for Lyme disease». They are working on it, she says, “but it is not active yet.”

Although this general overview of the state of the disease in our country is missing, there is data that allows us to glimpse that the disorder is a growing problem in Spain. For example, Estévez’s team conducted a study on hospitalizations associated with the disorder between 2005 and 2019 that showed a significant increase in admissions, as well as an expansion in the geographic distribution of the disease.

During the period analyzed, 1,865 patients admitted with Lyme disease were registered, with an increase in hospitalizations in those 15 years of 191%, points out the report, which details that the most frequent problem among the admitted patients was neurological impairment. “Evidently in this study all data at the outpatient level are lost, but it does allow for an estimate of the impact of the disease,” says the researcher, who recalls that “the appearance of more cases is related to the existence of the transmission vector.” the ticks.

“The more vectors there are in certain regions, the more disease occurs.” In the study, the areas with the most patient admissions were Asturias (16%) and Galicia (13%), although the increase in hospitalizations occurred in all the autonomous communities except Extremadura.

Ana del Cerro She is a researcher in the Animal Area of ​​the Regional Agri-Food Research and Development Service (SERIDA) of Asturias. For years he has been studying Lyme disease in the region, which “due to its temperate and humid climate, abundance and variety of flora and domestic and wild species, brings together very favorable conditions for the survival and maintenance of free phases of many species of ixodid ticks that remain active most of the year and have abundant animals on which to feed and thus perpetuate their cycles. Her team estimates that the prevalence of bacteria of the genus Borreliathe causes of Lyme disease, It is situated «around 4% of the adult ticks collected of vegetation throughout the entire province.

Traditionally, the humid zone of Spain, the northern half of the peninsula, has been associated with a greater presence of Ixodes ricinus, the tick that is most associated with the transmission of Lyme disease, although the truth is that in Spain there is also a lack of a real overview of the ticks that exist in the peninsula and the diseases they transmit. This mapping is currently being carried out by the GARES project, which started a year ago.

Ticks are one of the disease vectors that the World Health Organization (WHO) has put under scrutiny due to the possibility that their impact will increase in the coming years, boosted by factors such as climate change. These arthropods, in fact, have just entered the National Plan for Surveillance and Control of Vector-Transmitted Diseases, the third part of which was presented by the Ministry of Health this week.

Main disease transmitted by ticks

“Lyme disease is considered the main tick-borne disease in Europe, it is time to act,” he claims. Julia Ruiz, coordinator of the Public Health Working Group of the Spanish Society of General and Family Physicians (SEMG), who emphasizes that “there are several challenges to address when it comes to the disorder.” Thus, in addition to epidemiological surveillance and a greater commitment to research into the disease, it is also essential to promote greater awareness and sensitization about the disorder, “both among the population and among health professionals.”

It is necessary to think about the possibility of the disease, says the specialist, first to protect yourself when going out into the field, and then to detect the disease in its early stages, when its progression can be stopped through antibiotic treatment. Acting early is key, he continues, because without treatment, the infection can spread throughout the body, mainly affecting the joints, heart and nervous system, although the radius of action of the disease is extensive. The neuroborreliosisa disorder of the central nervous system that is considered the main complication of the disease, occurs in around 10% of cases, according to data pending update from the European Center for Disease Control (ECDC).

Although it is difficult to detect this disease that is an expert in camouflage, there are some signs that can help, says Ruiz. For example, it must be taken into account that a characteristic sign of the infection is the appearance of the so-called erythema migrans, the rash that was reminiscent of a target that Carla, Rocío Muñoz’s daughter, had. “It is a symptom that should make you consult with a specialist,” says Ruiz who, however, remembers that This skin injury does not occur in all cases.. In the early phase, joint pain, headache, fever, chills, fatigue may also appear… «It can be difficult to identify by the symptoms, which is why a fundamental key to fighting the disease is prevention. Properly protecting yourself when going to the countryside, for example by wearing long-sleeved clothing, with socks over your pants and also using repellents to reduce the risk of being bitten, is necessary,” recalls the specialist.

It is also important to check your body carefully when you have been in an area of ​​abundant vegetation. This check is essential since, If detected and removed in time, the tick will not be able to transmit the bacteria that causes the disease., remember. The tick must be removed preferably within 24 hours and always using blunt-edged, fine-tipped tweezers that must be held firmly before pulling upwards, taking care not to crush the animal. «Do not use alcohol, oils or try to burn them because if the tick feels attacked that is when it will inoculate any pathogen, which is not only the agent of Lyme disease, but also responsible for other problems, such as babesiosis, ricketsiosis, etc. », says Estévez.

Beyond raising awareness among the population about the risk posed by ticks, those affected by Lyme disease are also calling for greater knowledge of the disorder by the medical community and the improvement of both research and diagnostic techniques. the illness. This is what he points out Olga Gomez, who spent 13 years without giving a name to what was happening to her and even today continues to feel “helpless” in the health system. «No one understands you despite having the diagnosis. It is terrible but sometimes I have wished I had cancer and not this because that would mean having access to protocols, recognition of the disease and treatment, even if it might not work,” muses this woman from Valladolid who, like the rest of the affected women consulted, is tired of “the disorder being considered something foreign to Spain, something that is only associated with the US, Canada or central Europe despite the fact that it has been shown that it is also a serious problem here.”

«To this day all I want is for what happened to me not to happen to more people», he remarks. Next to her, the American Mary Kay, nods with each of her words. Her life changed 24 years ago, when her daughter Andrea was bitten by a tick while on vacation in Galicia. It also took more than 10 years to have a diagnosis. «She was a 17-year-old girl who has not been able to live. She is now 41 and all of her dreams are broken. This disease steals your life. And it can happen to anyone,” she laments. “We have to avoid it.”

SIGNS. It can cause skin, rheumatic, neurological or cardiac manifestations.

LYME. The disease has been known since ancient times, but its cause was not identified until 1977.

DETECTION. Laboratory tests can fail due to cross-reactions.

PROTECT YOURSELF. Wear pants and a long-sleeved shirt in the field and wear light-colored clothing.

FOOTWEAR. In risk areas, avoid sandals. Better boots and socks over pants.

REPELLENTS. In areas with a lot of vegetation, it may be useful to use 0.5% permethrin repellents.
