RESUMEN
Objective:To analyze and compare the differences between the epidemiological data and clinical indicators of confirmed and suspected undiagnosed cases of COVID-19 in Changning District， Shanghai. Methods:A retrospective comparative study was conducted. We included 20 confirmed and 34 suspected but undiagnosed COVID-19 cases from January 20 to February 29， 2020. We analyzed the differences in epidemiological history， early clinical symptoms， blood routine indicators， and clinical imaging characteristics between the two groups. Results:The epidemic status of COVID-19 in Changning District of Shanghai was mainly imported， and most cases were promptly confirmed. Early clinical symptoms of confirmed and suspected undiagnosed cases often manifested as respiratory symptoms such as fever and dry cough. Compared with the confirmed cases， the cell counts of leukocytes， eosinophils， and neutrophils in suspected undiagnosed cases were significantly higher. Also， the concentration of serum C-reactive protein in suspected cases was higher than that in confirmed cases （P=0.230）. The clinical imaging manifestations of confirmed cases were mainly ground glass opacity （GGO） scattered in both lung leaves， while the suspected undiagnosed cases mainly manifested as plain patch opacity， and the distribution of GGO was more irregular. Conclusion:There exists significant difference in blood routine indicators and clinical imaging features between confirmed and suspected cases of COVID-19.
RESUMEN
Objective To understand the epidemiological characteristics of COVID-19 epidemic in Huangpu District of Shanghai, and to provide scientific evidence for prevention and control of COVID-19. Methods Descriptive statistics were used to study the suspected and confirmed cases of COVID-19 reported from January 21 through March 10, 2020 in Huangpu District, Shanghai. Results A total of 120 suspected cases of COVID-19 were reported, of which 12 were diagnosed and 108 were excluded.The first confirmed case was reported on January 21, and the last case was on February 10; the majority (11/12) of the confirmed cases were reported from January 21 through February 1.The average duration of time from the symptom onset to the first medical visit was 2.6 days, whereas the average duration from the first medical visit to the hospital diagnosis was 2.2 days.There were 15 suspected cases with a confirmed history of residence or tourism in Wuhan, in which 6 were confirmed cases.Moreover, 5 suspected cases had a confirmed history of contact with other confirmed cases, in which 3 were confirmed cases.Thus, exposure in Wuhan and exposure to confirmed cases were the most significant risk factors at this stage of the epidemic. Conclusion The 12 cases identified in Huangpu District of Shanghai are all adults, half of whom had confirmed history of exposure in Wuhan.The first cluster of COVID-19 cases in Shanghai is documented in Huangpu District.Epidemiological investigation reveals that the confirmed cases might be infectious the day before the symptom onset.
RESUMEN
Background: As malaria is among the leading public health problems globally as well as in India, early diagnosis and treatment of cases is one of the key interventions for its control and elimination. Present study was done to assess treatment-seeking behaviour and associated factors among malaria suspected patients.Methods: Present study was carried out at urban health and training center, Sagar, Madhya Pradesh. The hospital based prospective study by facility based identification of patients. Study was under taken from 1st Oct 2018 to 31st march 2019. All malaria suspected cases of fever cases who got tested for malaria. Purposive sampling technique. After a pilot study final questionnaire regarding treatment seeking behavior were used to collect information from 285 patients of fever data was analyzed in word excel 2007 using percentage and proportion.Results: In present study we found that out of 285 patients only 54 (18.94%) patient approached health facility within 24 hours. Majority of patient 93(32.63%) adopted self medication practice, 20.00% patient, who did nothing and waited for self resolution of fever. Majority of 39.82% answered mildness of disease as a reason for delay in getting treatment.Conclusions: A low proportion of malaria-suspected patients sought treatment within 24 h of fever onset compared to the national target. Awareness about the advantage early treatment-seeking need to be increased through health education and behavioural change communication.

Objective To understand the serological detection of suspected measles cases in Xicheng District of Beijing,and provide basis for monitoring and prevention of measles.Methods Detection results of 200 blood speci-mens and age distribution of suspected measles cases in Xicheng District of Beijing in 2011 -2014 were analyzed. Results The positive rate of serological detection of suspected measles cases in 2011-2014 was 32.50%(65/200);positive rates in each year were 12.00%,4.35%,33.90%,and 44.09% respectively;there was significant differ-ence in the positive rate of serological tests in different years(P 24 years old,positive rates of serological detection were 35.38% and 34.02% respectively;31 cases (15.50%)received vaccination of measles;vaccine coverage rate in IgM antibody positive cases was lower than IgM antibody negative cases (3.08% vs 21 .48%,P <0.001 ).Conclusion Positive rate of serological detection de-creased in 2012,then increased year by year,for children under 5 years,measles are controlled by immunization with measles vaccine,in order to achieve the goal of eliminating measles effectively,control and prevention of adult measles is of great significance.

@#ObjectiveTo investigate the diagnosis and correlative factors of suspected severe acute respiratory synd rome (SARS) cases, and finally, complete the diagnosis and treatment.MethodsTo analyze the clinical, laboratory data,chest radiog raph and treatment of 100 suspected SARS cases.ResultsAmong 100 suspected SARS cases,66 were diagnosed as SARS,4 were mycoplasma l pneumonia, 2 were pulmonary tuberculosis,the others were general bacteria pne umonia.Conclusions SARS hasn't characteristic clin ical manifestation.Because there is not a gold diagnosis standard up to now, the disinfection and isolation of suspected SARS cases should be treated as SARS c ases. In order to prevent missed and misdiagnosis, the diagnosis and treatment s hould be synthetically thought.
