1.WHO International Health Regulations Emergency Committee for the COVID-19 outbreak
Epidemiology and Health 2020;42():e2020013-
To discuss whether the coronavirus disease 2019 (COVID-19) outbreak constitutes a Public Health Emergency of International Concern (PHEIC), World Health Organization (WHO) organized the 15-member International Health Regulations Emergency Committee (EC). On January 22-23 and January 30, 2020, EC convened and discussed whether the situation in China and other countries would constitute PHEIC and issued recommendations for WHO, China and the international community. Based on the recommendations of EC, WHO declared the COVID-19 outbreak a PHEIC. One of the purposes of the declaration of PHEIC was to alarm countries with weak public health infrastructures to prepare promptly for emerging infectious diseases (EID) and provide WHO with a framework for proactively supporting those countries. On February 3, 2020, WHO proposed the 2019 COVID-19 Strategic Preparedness and Response Plan, which includes accelerating research and development (R&D) processes as one of three major strategies. On February 11-12, 2020, WHO held the Global Research and Innovation Forum: Towards a Research Roadmap for COVID-19. The fact that a COVID-19 R&D forum was the first meeting convened after the PHEIC declaration testifies to the importance of R&D in response to EID. Korea has demonstrated a remarkable capacity in its laboratory response by conducting high-throughput COVID-19 testing and utilizing innovative drive-through samplings. These measures for early detection and screening of cases should be followed by full efforts to produce research-based evidence by thoroughly analyzing epidemiological, clinical and immunological data, which will facilitate the development of vaccines and therapeutics for COVID-19. It is expected that Korea plays a global partner for COVID-19 research by actively participating in immediate and mid/long-term priorities jointly led by WHO and global partners.

The 2015 Middle East respiratory syndrome (MERS) outbreak in the Republic of Korea, which started with an imported case and spread throughout the country with a total of 186 cases, revealed the vulnerabilities of the health-care system of the country. The situation was compounded by the unique health-care settings in the Republic of Korea, including crowded emergency departments and large numbers of hospital visitors seeking care at multiple hospitals. To assist with the outbreak response, the Ministry of Health and Welfare of the Republic of Korea hosted several international joint missions that provided valuable information and recommendations for MERS control and prevention of future outbreaks. This report briefly summarizes the missions’ outcomes and discusses their positive impacts.

We examined the hepatitis G virus infections among 227 Koreans who were healthy or were suspected of hepatitis and determined the phylogenetic relationship based on a part of the NS-5 region of 5 positive samples. Viral RNA was extracted from sera and cDNA was synthesized and subsequently amplified by RT-PCR (reverse transcription-polymerase chain reaction) or RT-nested PCR using random hexamer and NS-5 specific primers (470-20-1-77F, 470-20-1-211R, HGVNESTFO, HGVNESTRE). Five positives were found to belong to samples of patients showing symptoms of viral hepatitis. Primers used for PCR or nested PCR were derived from the NS-5 region. On the other hand, no amplification was detected using primers derived from the 5'-NCR (G-146F, G-401R). We performed TA cloning and sequencing of 5 amplified fragments, and their sequences were compared with those of foreign isolates of HGV. The phylogenetic analysis using MegAlign programme of DNAstar has shown that the Korean isolates are clustered on the phylogenetic tree. In summary, we confirmed the hepatitis G virus infection in 5 cases out of 12 patients showing the symptoms of viral hepatitis. The phylogenetic analysis of sequences of 5 amplified fragments showed that their relations to each other were closer than those to the foreign HGV isolates reported.

Group B coxsackieviruses (CVBs) are a group of common human pathogens producing various clinical symptoms. Although the virology of CVB is well known, there is limited information on viral pathogenesis and the relationship between clinical symptoms and viral phenotype, particularly for CVB type 2 (CVB2). In 2004 in Korea, two CVB2 strains were isolated: CB2/04/279 from stool of an acute myocarditis patient with heart failure and CB2/04/243 from an aseptic meningitis patient. In this study, a high degree of homology was observed between the CB2/04/279 and CB2/04/243 full genome sequences. The two Korean CVB2 isolates had 93.1% homology compared to 82.1%–82.5% nucleotide sequence identity with the cardiovirulence-associated reference CVB strain Ohio-1 (CVB/O). CVB2-induced pathogenesis was analyzed, focusing on virus-induced pathology of various tissues in 4-week-old BALB/c inbred male mice. Myocarditis developed and extensive pancreatic inflammation was observed in all mice infected with CB2/04/279 or CVB/O, but not in animals infected with CB2/04/243. This is the first report of the full-genomic sequence and pathogenesis of the CVB2 strain isolated from an acute myocarditis patient in Korea.

We describe the global status of measles control and elimination, including surveillance and vaccination coverage data provided by the World Health Organization (WHO). Since 2000, two doses of measles vaccine (MCV2) became recommended globally and the achievement of high vaccination coverage has led to dramatic decrease in the measles incidence. Our finding indicates that, in the Western Pacific Region (WPR), substantial progress has been made to control measles transmission in some countries; however, the measles virus continues to circulate, causing outbreaks. The Republic of Korea (ROK) experienced a series of resurgence of measles due to the importation and healthcare-associated transmission in infants, however overall incidence and surveillance indicators met the WHO criteria for measles elimination. The ROK was verified to be measles-free along with Australia, Mongolia, and Macau, China in 2014. One of the effective elimination activities was the establishment of solid keep-up vaccination system in school settings. The lessons learnt from the measles elimination activities in Korea may contribute to enhancing the surveillance schemes and strengthening of vaccination programs in member countries and areas of WPR.

We have determined and analyzed the full-length cDNA sequence of a coxsackievirus B3 (CVB3) Korean isolate (CVB3-Korea/97) which has been known as a general human pathogen. The whole genome contains 7,400 nucleotides and has a single large open reading frame with 6,555 nucleotides that encodes a potential polyprotein precursor of 2,185 amino acids. The genome also contains a 5' non-coding region (NCR) of 741 bases and a 3' NCR of 104 bases followed by poly(A) tail. Sequence homologies of nucleotides and deduced amino acids between the CVB3-Korea/97 strain and the prototype (Nancy strain) were 81.7% and 91.5%, respectively. The genes encoding the functional proteins including viral protease and RNA dependent RNA polymerase showed higher homology than those encoding the structural proteins. We have further analyzed the sequences of 5' NCR, VP1 and VP2 of CVB3-Korea/97, which are known as cardiovirulent determining factors at the nucleotide and amino acid levels. Although the CVB 3-Korea/97 strain was isolated from an aseptic meningitis patient without cardiomyopathy, its 234th nucleotide and 165th amino acid were uracil and Asn as same as those of other cardiovirulent strains one. However, the 155th amino acid of VR1, which closely associated with cardiovirulence, was replaced with Arg155 by single nucleoptide substitution from A2916 to T2916. Moreover, additional amino acid substitutions were observed in the flanking region of Asp155. Taken together, aminoacid(s) substitution in VP1 may play a critical role in determining cardiovirulence of the CVB3-Korea/97 strain rather than individual nucleotide replacements in the 5' NCR and/or an amino acid substitution in VP2.
