The 65th Medical Brigade and Medical Department Activity-Korea, in collaboration with the Migratory Birds Research Center, National Park Research Institute, conducted a migratory bird tick-borne disease surveillance program on Chilbal Island during 2016. Chilbal Island is a small, remote, uninhabited government-protected island in southwestern Jeollanam Province, Republic of Korea (ROK). Ticks were collected from nest soil and litter of the Ancient Murrelet, Synthliboramphus antiquus, using Tullgren funnels. A total of 4 Ixodes ticks (3 male Ixodes uriae and 1 female Ixodes signatus) were collected. The principal hosts of I. uriae are pelagic birds that have a largely circumpolar distribution. Ixodes signatus parasitizes other migratory birds in coastal areas of western North America and eastern Asia. This is the first report of I. uriae from the ROK.

The 65th Medical Brigade and Medical Department Activity-Korea, in collaboration with the Migratory Birds Research Center, National Park Research Institute, conducted a migratory bird tick-borne disease surveillance program during 2014–2015 on two small, remote, uninhabited islands, Hong (Gull) Island, southern Gyeongnam Province, and Nan Island, western Chungnam Province, Republic of Korea (ROK). Argasid ticks were collected from Black-tailed Gull (Larus crassirostris) nestlings that had recently died and associated nest soil/litter, and all tick life history stages were identified morphologically. Because morphological keys are unreliable for the identification of adult and nymphal argasid ticks, identifications were confirmed by genotyping using polymerase chain reaction techniques. A total of 29 Ornithodoros capensis larvae and 2 Ornithodoros sawaii larvae were collected from 4 of 7 (57.1%) Black-tailed Gull nestlings that had recently died. An additional five O. capensis (2 males, 1 nymph, and 2 larvae) were collected from nest soil/litter. Only O. sawaii larvae (2/41, 4.9%) were collected from dead Black-tailed Gull nestlings on Nan Island. This is the first report of O. capensis from these seabird breeding islands.

The 65th Medical Brigade (MED BDE)/Medical Department Activity-Korea (MEDDAC-K), in collaboration with the Migratory Birds Research Center, National Park Research Institute, conducted migratory bird tick-borne disease surveillance at six small, remote, uninhabited islands near the western (Nan Island), southwestern (Chilbal, Gugul, Gaerin, Hong, and Sogugul islands) and southeastern (Hong Island) coastal areas of the Republic of Korea (ROK) during 2009 and from 2014–2017. Ticks were collected from nest soil/litter of the Ancient Murrelet (Synthliboramphus antiquus), Japanese Murrelet (Synthliboramphus wumizusume), Swinhoe’s Storm Petrel (Hydrobates monorhis), Black-tailed Gull (Larus crassirostris), Pacific Swift (Apus pacificus), and Streaked Shearwater (Calonectris leucomelas) using Tullgren funnels. Ticks also were collected from recently dead nestlings of Swinhoe’s Storm Petrel and Black-tailed Gull at Gugul, Sogugul, Gaerin, Nan, and Hong islands, and single ticks were collected from vegetation (tick drag) and a human bitten on Chilbal Island. A total of 1,578 ticks (61 females, 122 males, 290 nymphs, and 1,105 larvae), belonging to four genera and six species, were collected. Ornithodoros capensis (73.00%; 1,152) was the most commonly collected tick on migratory seabirds, followed by Ornithodoros sawaii (26.55%; 420), Ixodes uriae (0.19%; 3), and Ixodes signatus (0.13%, 2). One (0.06%) Haemaphysalis flava was collected by tick drag and one (0.06%) Amblyomma testudinarium was collected while biting one of the survey members. Ornithodoros species were identified morphologically and confirmed using polymerase chain reaction (PCR) techniques. This is the first record of O. sawaii collected from nest soil/litter during the 2017 nesting season of the Pacific Swift and Streaked Shearwater in the ROK.

Tick-borne disease surveillance was conducted from March–October 2014 in two southeastern provinces, including three metropolitan areas, in the Republic of Korea (ROK). Three general habitats were surveyed: Grasses (grasses and herbaceous and crawling vegetation), Forests (pine, larch, deciduous, and mixed), and Forests+Grasses. A total of 40,048 ticks (1,480 adults; 24,201 nymphs; 14,367 larvae) belonging to three genera and six species were collected. Haemaphysalis longicornis (84.25%; 33,741) was the most commonly collected tick, followed by Haemaphysalis flava (14.52%; 5,816), Ixodes nipponensis (1.09%; 436), Amblyomma testudinarium (0.07%; 27), Haemaphysalis phasiana (0.06%; 23), and Ixodes turdus (0.01%; 5). Overall, adult ticks accounted for only 3.70% of all ticks collected, while nymphs and larvae accounted for 60.43% and 35.87%, respectively. The proportion of H. longicornis nymphs was highest beginning in March (99.51%), slowly declined through July (82.01%) and then rapidly declined to a low in October (6.45%). Large increases in the proportion of H. longicornis larvae were observed in August (42.05%), September (84.19%) and October (93.55%) following increased numbers of adults collected in June (4.20%), July (17.99%) and August (9.79%). Haemaphysalis flava adults and nymphs were commonly collected from April–May and October, while larvae were first collected from July, with peak numbers collected in August and low numbers collected during September–October. The proportion of I. nipponensis adults was highest in March (75.34%), declined to a low in July (0%), and then increased in September (60.00%) and October (90.32%). Larvae were collected only in August–September and accounted for 64.29% and 20.00% of all I. nipponensis collected during those months. Similar proportions of males and females of H. flava (51.47% and 48.53%, respectively) were collected from all habitats, while significantly more I. nipponensis males (62.20%) were collected than females (37.80%). Conversely, the proportion of H. longicornis females (80.00%) collected was significantly higher than for males (20.00%). Overall, the mean number of ticks collected/hr of collection for all habitats was 156.06/hr of collection. Similar numbers were collected/hr for Forests (172.61) and Grasses (168.64), while lower numbers were collected/hr for Forests+Grasses (128.12).

Globally, vector-borne diseases are an increasing public health burden; in the United States, tick-borne diseases have tripled in the last three years. The United States Centers for Disease Control and Prevention (CDC) recognizes the need for resilience to the increasing vector-borne disease burden and has called for increased partnerships and sustained networks to identify and respond to the most pressing challenges that face vector-borne disease management, including increased surveillance. To increase applied research, develop communities of practice, and enhance workforce development, the CDC has created five regional Centers of Excellence in Vector-borne Disease. These Centers are a partnership of public health agencies, vector control groups, academic institutions, and industries. This special issue on tick and tick-borne disease surveillance is a collection of research articles on multiple aspects of surveillance from authors that are affiliated with or funded by the CDC Centers of Excellence. This body of work illustrates a community-based system of research by which participants share common problems and use integrated methodologies to produce outputs and effect outcomes that benefit human, animal and environmental health.

Since its re-emergence in 2005, chikungunya virus (CHIKV) transmission has been documented in most Indian states. Chikungunya virus (CHIKV) has caused several major epidemics globally over the last two decades and is quickly expanding into new areas. Aim: To study different demographic variables in the outbreaks of Chikungunya infection in Jharkhand from January 2017 to December 2020. Methods: Surveillance data were collected monthly, as a part of the Integrated Disease Surveillance program, India. The clinical denition of cases and outbreak was used for the surveillance rates and outbreaks. Chikungunya outbreaks were analyzed in different districts of Jharkhand for a period of 4 years (2017 - 2020) and trends were analyzed according to age, sex, residency and seasonality. Results: Two, three, three and one outbreaks occurred in 2017, 2018, 2019 and 2020 respectively which caused ten, ve hundred and thirty, thirty three and four cases respectively altogether in Jharkhand . In 2020, due to SARS-CoV2 infection, the cases were not reported from all over the districts of Jharkhand. There was minor difference in occurrence among genders. A seasonal pattern was also observed with the outbreaks occurring maximum in the months of August to October. The age group of patients who were maximum affected were of 31-40 years followed by 21-30 years. Conclusion: The study ndings will be useful to improve the public health preparedness in tackling future outbreaks in regions with a high susceptibility for CHIKV.
