Autochthonous dengue infections have not been reported in Ningbo, People's Republic of China since 1929. In August-October 2004, an outbreak of dengue fever was confirmed in Xiaolin, Cixi, Ningbo. Of 83 cases reported, 68 were laboratory confirmed. Fifty-three percent (34 of 64) of the cases had IgM antibodies to dengue virus. Dengue virus serotype-1 was(More)
There are many phenomena in nature, such as earthquakes, landslides, floods, and large-scale mineralization that are characterized by singular functions exhibiting scale invariant properties. A local singularity analysis based on multifractal modeling was developed for detection of local anomalies for mineral exploration. An iterative approach is proposed(More)
OBJECTIVE To examine vibrio cholera (V.C) in aquatic products of littoral area, Zhejiang Province and to provide scientific evidence for administration of aquatic products and cholera epidemic control. METHODS All 990 samples of aquatic products collected from local markets, eateries and aquafarms in three chosen areas. Samples were proliferated in(More)
BACKGROUND Scarlet fever is caused by group A beta-hemolytic streptococci (GAS). The clinical syndrome has receded in recent years, but occasionally explosive outbreaks do occur likely due to the emergence of GAS with virulence factors peculiar to this syndrome. METHODS Following the notification of an unexpectedly large number of scarlet fever cases(More)
BACKGROUND The reported coverage rates of first and second doses of measles containing vaccine (MCV) are almost 95% in China, while measles cases are constantly being reported. This study evaluated the vaccine coverage, timeliness, and barriers to immunization of MCV1 and MCV2 in children aged from 8-48 months. METHODS We assessed 718 children aged 8-48(More)
BACKGROUND Vaccine-preventable diseases cause more than one million deaths among children under 5 years of age every year. Public Health Workers (PHWs) are needed to provide immunization services, but the role of human resources for public health as a determinant of vaccination coverage at the population level has not been assessed in China. The objective(More)
Background: Bacillus Calmette-Guérin (BCG) vaccination is recommended for newborn infants worldwide to prevent tuberculosis. However, complications do occur inevitably in a very low rate, among which the most serious is disseminated disease. The disseminated bacillus Calmette–Guérin disease is a rare disease with high fatality, and can be seen among persons(More)
OBJECTIVE To observe the relationship of Chinese medicine (CM) syndrome pattern with heart function detected by ultrasonic cardiography and brain natriuretic peptide (BNP) level in patients with heart failure (HF). METHODS One hundred and sixteen inpatients of HF hospitalized in Dongfang Hospital from January, 2007 to January, 2009 were assigned to three(More)
Together with generalized self-similarity and the fractal spectrum, local singularity analysis has been introduced as one part of the new 3S principle and technique for mineral resource assessment based on multifractal modeling, which has been demonstrated to be useful for anomaly delineation. Local singularity is used in this paper to characterize the(More)
OBJECTIVE To study the evidence of severe acute respiratory syndrome (SARS) infection among close contacts to SARS patients and the level of sera IgG antibody in SARS cases. METHODS Specific IgG antibody against SARS-CoV in serum samples from contacts to patients, five months before an SARS outbreak in Beijing. Neutralized test, ELISA and immunity(More)
