[The Importance of Differential Diagnosis During Pandemic: A Case Report with Coexistence of COVID-19, Brucellosis and Crimean-Congo Hemorrhagic Fever]. / Pandemi Döneminde Ayirici Taninin Önemi: COVID-19, Bruselloz ve Kirim-Kongo Kanamali Atesi Birlikteligi Olan Bir Olgu Sunumu.

The coronavirus disease-2019 (COVID-19) pandemic, which affects millions of people around the world, has been affecting our country since March 2020. The fact that the symptoms such as fever, myalgia, headache, joint pain which are common in COVID-19 patients are quite similar to the symptoms of diseases such as Crimean-Congo hemorrhagic fever (CCHF) and Brucellosis. This may cause a diagnostic confusion in regions where these diseases are seen as endemic. In this report, a patient hospitalized with a pre-diagnosis of COVID-19 and diagnosed with acute Brucellosis, CCHF and COVID-19 during followup was presented. A 31-year-old female patient living in a rural area admitted to the emergency service with complaints of fever, weakness, headache, and body/joint pain. Physical examination revealed a temperature of 38.3°C, a pulse rate of 102/minute, and a peripheral capillary oxygen saturation of 97% in room air. The system examination was normal. In the laboratory findings, an increase in liver enzymes and acute phase reactants was observed and the platelet count was at the lower limit of the normal range. In terms of COVID-19, no involvement compatible with COVID-19 was detected in the thorax computed tomography (CT) of the patient whose nasopharyngeal and oropharyngeal mixed swab samples were taken.The patient was transferred to our infectious diseases service with a pre-diagnosis of COVID-19 and CCHF. Serum samples were sent to the Public Health Agency Microbiology Reference Laboratory Department (PHA-MRLD) for CCHF diagnostic tests and supportive treatment was started. Brucella Rose Bengal and Coombs' immuncapture (1/1280 titer) tests were found as positive in the patient, who was examined for brucellosis because of living in a rural area and having a history of consuming fresh dairy products. In the tests performed at PHA-MRLD, CCHF-specific IgM positivity and the presence of viral RNA were detected. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) reverse-transcriptase polymerase chain reaction (RT-PCR) test was negative. For Brucellosis, doxycycline and rifampicin were added to the treatment of the patient whom was given supportive therapy for CCHF. In the followup, the patient's fever was persisting and loss of taste and smell complaint developed. In this context, COVID-19 test was repeated and resulted as positive. Upon this, hydroxychloroquine sulfate treatment was started due to the recommendation of the current Ministry of Health Scientific Committee Guide. No new infiltration was detected in the chest radiography of the patient. The patient's fever subsided during follow-up and laboratory findings improved. The treatment of brucellosis was completed to eight weeks at the outpatient clinic. No problems were detected in the follow-up. This report was prepared because of a case with simultaneous brucellosis, CCHF and COVID-19 infections which could not be encountered in the literature review. As a result; in regions such as our country where both brucellosis and CCHF are seen as endemic, it is very important to keep these diseases in mind in the differential diagnosis of COVID-19 infection.

Risk Factors for Acute Brucellosis in Patients on the Day of Admission at Selected Hospitals of Abbottabad, Pakistan.

Brucellosis is a neglected zoonotic disease of ruminants. It causes severe health problems in humans and significant economic loss. Only a limited number of studies have been conducted in Pakistan to determine the prevalence of human brucellosis and related risk factors. The objectives of the current cross-sectional study were to determine the prevalence of anti-Brucella antibodies in sera collected from symptomatic patients at three hospitals of Abbottabad using a commercial slide agglutination test (SAT) and to determine risk factors for brucellosis for these patients. Five hundred blood samples were collected. A questionnaire was filled in for each patient to obtain information on age, gender, living area, brucellosis associated symptoms, associated risk factors, pregnancy and abortion history. A total of 13.6% (n = 68) patients were found to be SAT positive and in 83.3% (n = 57) of these samples Brucella DNA was detected by genus specific RT-PCR for BCSP-31 gene. Statistical analysis was performed to determine odd ratios, risk ratios, 95% confidence intervals, and p-values. The prevalence of brucellosis by SAT was reported to be higher in women (14.6%, n = 44) than in men (12.1%, n = 24). The age group 25-50 years was found to be at higher risk for brucellosis (14.5%, n = 50) "animal contact" was reported as the main risk factor followed by "consumption of raw animal products." Out of 131 pregnant women and 21 patients had abortion, the seropositivity of Brucellosis was 9.9% and 23.8%, respectively. The present study reports a striking prevalence of brucellosis among patients including pregnant women at three hospitals of Abbottabad. These findings may foster strategies for controlling human brucellosis at household level, raising of awareness about brucellosis in hospital and family doctors, and finally in setting up an eradication program in the dairy industry.

Brucellosis with splenic abscess in a child initially suspected to have covid-19.

COVID-19 can manifest with signs and symptoms related to many different systems. Therefore, in the examination of almost every patient, COVID-19 infection is excluded first This may cause other diseases to be missed, as almost occurred in the case of a 15-year old boy with brucellosis and a splenic abscess. Public and health care personnel fear of COVID-19 may cause more harm than the virus itself.

Brucellosis in a patient diagnosed with Coronavirus Disease 2019 (COVID-19).

Brucellosis is a common zoonotic infection. Brucellosis typically presents with fever, weakness, night sweats, and arthralgias. Symptoms associated with Coronavirus Disease 2019 (COVID-19) and infection with Brucella spp. are similar to one another, which may lead to delayed diagnosis of the latter condition. There are no previous reports of brucellosis in a patient previously diagnosed with COVID-19. We present here the case of a 20-year-old male who we diagnosed with brucellosis after joint pains and fever that persisted after resolution of COVID-19.
