Epidemiological features of domestic and imported cases with COVID-19 between January 2020 and March 2021 in Taiwan

Abstract Background and Aim: The aim of this study was to description of the epidemiological features and hotspot of COVID-19 in Isfahan province of Iran.Method: In this descriptive, retrospective cohort, multicenter study, all patients admitted to one of the hospitals or health networks of Isfahan province from 3rd February to 13th June 2020 due to RT-PCR (Reverse transcription-polymerase chain reaction) test were enrolled to study. Trained staff followed up participants for two weeks by a Telephone number, and the outcome was recorded.Result: Up to 13 June, 41,498 patients recruited and their data were analyzed; the incidence of COVID-19 was 27.5% (95% CI: 27.1, 28.2). Among the participants with the positive test, 93.2% of them, treated by outpatient basis or discharged, 2.1% were hospitalized, and the case fatality rate (CFR) was 4.8%. Khansar and Aradestan was the hotspot of COVID-19 and had the highest incidence among cities of Isfahan province. Najafabad, Khomeinishahr, and Shahinshahr&Meymeh had the highest imported cases of COVID-19 to the capital of Isfahan province, Isfahan city. Also, Charmahal & Bakhtiari, Khuzestan, and Fars provinces had the highest number of imported cases from other provinces to Isfahan city. We found that 77.3% of intra-province imported cases and about 83% of inter-province cases were imported after reducing lockdown.conclusion:The incidence and fatality of COVID-19 in Isfahan province is alarming. Inter-city and inter-provincial unnecessary travels have a high impact on the transmission and spread of the COVID-19. Applying more restrictions will prevent this from happening. It is advised to restrict the inter cities travels again by policy makers for the benefit of public health.

There was an outbreak of Dengue fever on September 5, 2019, in Hainan Province, which has not been endemic for 28 years. We aim to describe the clinical and epidemiological features of the 2019 outbreak in Hainan Province and identify the cause. All type 1 Dengue fever cases that occurred in this outbreak of Hainan exhibited mild clinical symptoms. The epidemiological investigations indicate that the outbreak might originate from workers in the Xiuying area, Haikou City, form a concentrated outbreak, and then spread out. Bayesian phylogenies results and epidemiological data were used to infer a likely series of events for the dengue virus’s potential spread and trace the possible sources. The strains’ sequences were close to a sequence from the nearby Guangdong province, supporting the hypothesis that the dengue virus was imported from Guangdong province and then spread across Hainan province. Furthermore, it is interesting that two other strains didn’t group with this cluster, suggesting that additional introduction pathways might exist. The study indicated that the dengue fever epidemic presented two important modes in Hainan. Firstly, epidemics prevalence was caused by imported cases, and then endogenous epidemics broke out in the natural epidemic focus.

Abstract Background: Leishmaniasis is a vector-borne disease caused by several species from genus Leishmania. An increase in the number of cases related to human movement has been informed in the last years. Due to the increase of suspicious leishmaniasis cases arriving in Cuba during 2017, an general analysis is presented herein. Methods: Clinical samples were collected from 5 patients suspicious of leishmaniasis, received from January to December 2017 at the Institute of Tropical Medicine Pedro Kourí, Cuba. Skin lesion samples were analyzed using different diagnostic assays: direct smear, histological examination, and molecular analysis for species identification. Epidemiological and demographic data were requested from each case and analyzed. Treatment and follow up of patient was also performed.Results: Five cases were confirmed as Leishmania infection according to microscopic observation and molecular methods results. PCR-18S, PCR-N/RFLP and PCR-F/RFLP identified the following species: L. panamensis (2 cases), L. braziliensis (1 case), L.panamensis/L.guyanensis (1 case), L. mexicana complex (1 case). In treated patients, drugs were well tolerated, cure were documented and no relapse have been currently reported (3 years later).Conclusions: Clinical characteristics, demographic data, and epidemiological features of infection for each case evidence the potential risk related with travel to endemic areas of leishmaniasis.

Iranian Patients

Background: The outbreak of Coronavirus Disease 2019 (COVID-19) has led to a major concern for those who are more vulnerable to infections. Objectives: This study aimed to evaluate the most important risk factors for severe COVID-19 pneumonia. Methods: This retrospective study included information on clinical and epidemiological features of 105 patients with severe COVID-19 pneumonia hospitalized in Tajrish Hospital, Tehran, Iran. Initially, the medical records of the patients were investigated, and an interview was conducted based on a pre-prepared checklist to seek information about symptoms, past medical history, medication history, and behavior before hospitalization. Results: Out of 105 participants, 76 (72.5%) cases were male, and 54 (51.4%) patients were older than 54 years old. The majority of the patients (n=18; 17.1%) had both hypertension and diabetes (n=12; 11.4%). Metformin (n=36; 34.3%) was the most used medication amongst the studied patient. In addition, 24 (22.9%) patients were recreational hookah smokers, and the majority (75%) of them were under the age of 46 years old. Eventually, 19 patients were excluded from the study, of whom 11 individuals had diabetes, and 10 cases were using metformin. Conclusion: Apparently, hookah smoking played a critical role in the spread of COVID-19 in Iran and has made younger people more susceptible. In addition to older age, the immunosuppressive effects of Metformin seem to make diabetic patients with an impaired immune system more vulnerable to severe COVID-19 pneumonia. More studies on the immune system of vulnerable individuals by identifying their differences can help to protect them.
