Pathogenesis of the Chikungunya virus and the host immunity response

摘要

Along with the running COVID-19 pandemic by the severe acute respiratory syndrome coronavirus 2,the Chikungunya virus is already known as the causative agent of re-emerging Chikungunya fever in many countries after several years of latency;and it’s certainly one of the most important clinical issues possibly due to the lack of appropriate vaccination.Therefore,continuous study and monitoring of this disease outbreak demand attention by the relevant health professionals.Present review has been written in the light of the recently available reports on the Chikungunya virus infection.The genomic structure and its impact on the viral epidemiology,the possible protective immunity,and the infection mitigation strategies have been discussed.It’s already well known that the Chikungunya virus can start infection after getting entrance into the blood circulation through the mosquito bites followed by the dissemination into the major organs like liver,brain,eye,joints and lymph nodes in order to inaugurate the infectivity.Apparently,the occurrence of death is very rare but the extreme fatality and morbidity may occur if the patient has other underlying disease conditions.The molecular aspects of the virus,the site-specific damages caused by the viral infection,and finally,the public awareness of such viral infection as discussed in the current review would help to maintain the public health sustainability especially in the developing countries whereby the knowledge on the required hygiene is poor.
