The confirmation of a new case of Crimean-Congo hemorrhagic fever in Salamanca has rekindled concern among the population and health authorities in Castile and León. This is the second diagnosis in the province in recent months and, although the disease is considered rare in Spain, Its severity makes each new case a warning sign for all public health agencies..
The patient, a 63-year-old man, was initially admitted to the Salamanca University Health Complex, where he presented symptoms compatible with this viral infection. From the first moment the possible presence of the virus was suspected due to the existence of a tick biteGiven the situation, standard protocols were activated, and he was transferred to Gómez Ulla Hospital in Madrid, a national reference center for this type of serious infectious disease, where he remains in stable condition under strict isolation measures.
The diagnosis was confirmed after analyzing samples sent to the National Microbiology Center, part of the Carlos III Health Institute. Authorities insist on the importance of specialized medical follow-up, due to the potentially serious nature of the disease and the ease of transmission in certain contexts.
The Regional Government of Castile and León, through the Epidemiology Section of the Territorial Health Service, has begun monitoring and tracking the patient's close contacts, both within their families and among the professionals who treated them. These individuals are required to monitor their temperature regularly and must immediately report any symptoms or changes in their health to the relevant epidemiologist.
The inter-institutional coordination protocol It was activated from the first suspicion, with collaboration between the Regional Government, the Ministry of Health, and the Carlos III Health Institute, thus speeding up sample collection, diagnosis, and the adoption of preventive measures to avoid subsequent infections.
How is Crimean-Congo hemorrhagic fever transmitted?
The virus responsible for this disease is transmitted mainly by the bite of ticks of the Hyalomma genus.. However, it is not the only way of contagion, since there is a risk of transmission between humans, especially through contact with the blood or other bodily fluids of infected people. Therefore, it is essential that both healthcare personnel and those who live with the patient scrupulously follow the recommended protective and biosafety measures.
In recent seasons, the province of Salamanca It has become one of the geographical areas with the highest incidence of autochthonous cases in Spain.According to various epidemiological surveillance agencies, more than 50% of national cases have been detected in this province, which has prompted more exhaustive monitoring and awareness campaigns aimed at the local population and visitors to rural areas.
Recommendations for prevention and protection
Health authorities insist that the best way to avoid contagion is protect yourself from exposure to ticks, especially when outings in the countryside or areas with dense vegetation and grazing animals. Among the most important recommendations are:
- Use light-colored clothing, long sleeves and long pants that cover the body completely.
- Check skin and clothing thoroughly after being outdoors, paying attention to areas such as the armpits, groin, behind the knees, and the scalp.
- Apply specific tick repellents both on the skin and in pets.
- Avoid sitting directly on the grass and walk preferably on marked paths.
- Go to a health center if you detect an attached tick. so that the extraction is carried out safely and completely.
These measures also apply to pets, as they can act as unwitting carriers of ticks and become vehicles for virus transmission if appropriate antiparasitics are not used.
Symptoms and clinical evolution
Crimean-Congo hemorrhagic fever initially manifests with Sudden fever, malaise, muscle aches and, in some cases, vomiting and headachesIn the most severe cases, a decreased platelets, liver damage, and internal bleeding, which justify the importance of early diagnosis and the need for hospitalization in specialized units.
There is no specific antiviral treatment with proven efficacy for the disease.Medical care focuses on symptom management, life support, and monitoring for possible complications. The reported case fatality rate is high compared to other tick-borne viruses, reinforcing the need for continued surveillance and communication across the various levels of the healthcare network.
Since the first case was reported in Spain in 2016, there have now been more than a dozen confirmed cases, most of them in rural areas of the western Iberian Peninsula, especially in Salamanca and its surrounding areas.
Factors influencing the appearance of cases
The presence of Hyalomma tick in the province of Salamanca and the existence of favorable ecological conditions -such as frequent contact with grazing animals and the climate suitable for the vector's development- have made the area a priority surveillance focus. In addition, bird migration routes and recent climate changes are cited among the possible causes of the virus settling in the peninsula.
When symptoms appear after a tick bite, it is essential go to a health center as soon as possible and inform medical personnel of any history of exposure in risk areas, in order to activate the early detection, isolation, and treatment protocol.
Crimean-Congo hemorrhagic fever, although still a rare disease, requires a rapid and coordinated response to prevent outbreaks and ensure the safety of both patients and healthcare personnel. The combination of epidemiological surveillance, up-to-date information, and preventive measures is essential to control its spread in our country.
