Manejo desde atención primaria de la infección por la viruela del mono (MPOX) en humanos / Management from Primary Care of monkeypox infection (MPOX) in humans

La viruela del mono (MPOX) es una zoonosis vírica endémica en países de África occidental o central que esporádicamente se exporta a otras regiones. En mayo del 2022, comenzó a ocurrir un brote mundial de viruela MPOX en varias naciones de Europa y Norteamérica. La mayoría de los casos notificados se identificaron a nivel ambulatorio y afectaron principalmente a hombres que tienen sexo con hombres (HSH). El contagio es por contacto estrecho con lesiones, líquidos corporales, secreciones respiratorias o con material contaminado, de persona o animal infectado. El cuadro clínico es similar a la viruela humana, con menor gravedad. Predomina la afectación cutánea leve y autolimitada tras dos a cuatro semanas. En HSH aparecen lesiones cutáneas atípicas debido a la manera de contagio. En ciertos grupos de riesgo pueden presentarse formas graves o complicaciones. La tasa de letalidad es de 3 a 6% según el clado responsable. El diagnóstico de sospecha se confirma con la detección del virus, a partir de exudados de las lesiones o costras, con técnicas de amplificación de ácidos nucleicos mediante reacción en cadena de la polimerasa (PCR) convencional o en tiempo real. El manejo clínico en la mayoría de los casos se realiza desde atención primaria (AP), mediante el control de los principales síntomas. Entre 5 a 10% requieren un manejo hospitalario y existen algunas opciones de tratamiento antiviral específico. Las vacunas frente a la viruela humana protegen contra la MPOX y se utilizan como profilaxis pre y posexposición a personas de riesgo. Las medidas para reducir la exposición al virus, es la principal estrategia de prevención de la MPOX. Además, el papel del médico de familia es clave para controlar la propagación del virus de la MPOX mediante la vigilancia activa y el diagnóstico temprano de la enfermedad.(AU)

Monkeypox (MPOX) is a viral zoonosis endemic in West or Central African countries that is sporadically exported to another area. In May 2022, a global outbreak of MPOX smallpox began to occur in several countries in Europe and North America. Most of the reported cases are identified at the outpatient level and mainly affect men who have sex with men (MSM). Transmission is by close contact with lesions, body fluids, respiratory secretions or contaminated material from an infected person or animal. The clinical picture is similar to human smallpox, with less severity. Mild, self-limiting skin involvement predominates after 2-4 weeks. In MSM, atypical skin lesions appear due to the mode of infection. Severe forms or complications may appear in certain risk groups. The case fatality rate is 3%-6% depending on the clade responsible. The diagnosis of suspicion is confirmed by detection of the virus from exudates of lesions or scabs, with nucleic acid amplification techniques by conventional or real-time PCR. Clinical management in most cases is performed in primary care (PC), by monitoring the main symptoms. Between 5-10% require hospital management and there are some specific antiviral treatment options. Human smallpox vaccines protect against MPOX and are used as pre- and post-exposure prophylaxis for persons at risk. Measures to reduce exposure to the virus are the main MPOX prevention strategy. In addition, the role of the family physician is key to controlling the spread of MPOX through active surveillance and early diagnosis of the disease.(AU)

SARS-CoV-2 is transmitted from person to person by inhalation or contact with respiratory droplets and aerosols. The median incubation period is 5.1 days. Fever, dry cough, dyspnea and fatigue are the most common symptoms. Almost half of the cases are asymptomatic. The spectrum of disease varies from mild (81%) to critical (5%). Older age, male gender and comorbidities negatively impact on the severity and mortality of COVID-19. The diagnosis of acute COVID-19 is made with RT-PCR or antigenic detection tests. In hospital patients, remdesivir reduces recovery time. Oral steroids are recommended for severe or critical cases requiring oxygen therapy or mechanical ventilation. Thromboprophylaxis is recommended in all severe and non-severe cases with high thrombotic risk. Antibiotherapy is limited to cases of high suspicion of bacterial superinfection. Mild-moderate and severe cases after discharge from hospital should be clinically monitored for a minimum period of two weeks.
