“…This happened because more than 60% (i.e., herd immunity threshold) of the population is recovered from the infection. Herd immunity can affect the epidemic transmission as it can downsize the spread of the infection [ 56 ]. Herd immunity is proposed as one of the techniques to control the COVID-19 epidemic outbreak [ 54 ].…”

In this paper, a new nature-inspired human-based optimization algorithm is proposed which is called coronavirus herd immunity optimizer (CHIO). The inspiration of CHIO is originated from the herd immunity concept as a way to tackle coronavirus pandemic (COVID-19). The speed of spreading coronavirus infection depends on how the infected individuals directly contact with other society members. In order to protect other members of society from the disease, social distancing is suggested by health experts. Herd immunity is a state the population reaches when most of the population is immune which results in the prevention of disease transmission. These concepts are modeled in terms of optimization concepts. CHIO mimics the herd immunity strategy as well as the social distancing concepts. Three types of individual cases are utilized for herd immunity: susceptible, infected, and immuned. This is to determine how the newly generated solution updates its genes with social distancing strategies. CHIO is evaluated using 23 well-known benchmark functions. Initially, the sensitivity of CHIO to its parameters is studied. Thereafter, the comparative evaluation against seven state-of-the-art methods is conducted. The comparative analysis verifies that CHIO is able to yield very competitive results compared to those obtained by other well-established methods. For more validations, three real-world engineering optimization problems extracted from IEEE-CEC 2011 are used. Again, CHIO is proved to be efficient. In conclusion, CHIO is a very powerful optimization algorithm that can be used to tackle many optimization problems across a wide variety of optimization domains.

“…Zika virus spread from Brazil to other countries in South America, eventually with mosquito-borne transmission to 87 countries and territories throughout the world (Musso, Ko, & Baud, 2019), including in the United States (US) with limited transmission in states (Florida and Texas) and widespread transmission in territories (Puerto Rico, US Virgin Islands, and American Samoa). Transmission in the Americas dropped significantly in late 2016, presumably related to sufficient herd immunity in areas of widespread transmission (Ribeiro et al, 2020). Modeling studies from work on the chikungunya virus suggest that sufficient herd immunity could suppress the widespread circulation of the Zika virus for at least 10 years (Ferguson et al, 2016).…”

“…Modeling studies from work on the chikungunya virus suggest that sufficient herd immunity could suppress the widespread circulation of the Zika virus for at least 10 years (Ferguson et al, 2016). However, cases continue to be reported to the Pan American Health Organization in 2019 from areas of Central and South America (Ribeiro et al, 2020). Other areas of the world (e.g., southeast and south Asia) have reported more recent outbreaks, suggesting that Zika virus remains an active threat to pregnant women and their infants in some regions of the world (Duong, Dussart, & Buchy, 2017;Grubaugh, Ishtiaq, Setoh, & Ko, 2019;Wongsurawat et al, 2018).…”

Zika virus was first identified in Uganda in 1947 but received little attention until 2015 when a large outbreak of Zika virus illness followed by an increased number of babies born with microcephaly occurred in Brazil. Zika virus spread rapidly throughout the Americas, and in 2016 was identified as a cause of microcephaly and other serious birth defects. Since that time, much has been learned about the Zika virus. The virus is primarily spread by the bite of Aedes species mosquitoes; however, other forms of transmission (e.g., sexual and intrauterine) have been recognized. Although postnatal Zika virus infection typically causes mild or no symptoms, effects on infants born to prenatally infected mothers can be severe and include structural birth defects and neurodevelopmental effects. The risk of a structural birth defect among infants born to mothers with confirmed or suspected Zika virus infection during pregnancy has ranged from 5 to 10%. The timing of Zika infection during pregnancy affects risk, with higher risks with the first‐trimester infection. Neurodevelopmental effects are seen even in infants who appear normal in the newborn period. Although cases of Zika virus infection have fallen in the Americas, the Zika virus remains an active threat in some regions of the world. The development of a Zika vaccine will require continued focus and investment. Until a Zika vaccine is available, prevention efforts for pregnant women include avoidance of travel to areas with active Zika transmission, avoidance of mosquito bites for those living in or traveling to areas with Zika transmission, and protection against sexual transmission.

“…Moreover, vaccination with a single serotype may increase the severity of a secondary infection, which ever occurred in Dengue virus with four serotypes (de Alwis et al, 2014). Similarly, vaccination with the bivalent HPV vaccine caused decline in the prevalence of HPV types 16 and 18 and cross-protection against non-vaccine types HPV 31, 33, and 45, but increased prevalence of non-vaccine, non-cross-protective HPV types (Brisson et al, 2016;Cameron et al, 2016;Ribeiro et al, 2020).…”

The COVID-19 pandemic has been a global threat. Through rapid and effective surveillance and control, the newly confirmed patients have been fluctuated at a very low level and imported case explained most of them through March, 2020 to the present, indicating China's response has achieved a stage victory. By contrast, the epidemic of COVID-19 in other countries out of China is bursting. Different countries are adopting varied response strategy in terms of their public health system to prevent the spread. Herd immunity has been a hot topic since the outbreak of COVID-19 pandemic. Can it be a possible strategy to combat COVID-19? To fully interpret the knowledge regarding the term upon the background of COVID-19-related health crisis, we aim to systematically review the definition, describe the effective measures of acquiring herd immunity, and discuss its feasibility in COVID-19 prevention. Findings from this review would promote and strengthen the international cooperation and joint efforts when confronting with COVID-19.
