Abstract Malaria is a serious Anopheles mosquito-borne disease. It is not endemic in Egypt but continues to be imported by travelers returning from endemic areas. The transmission of malaria in non-endemic areas is an extremely unusual event, but it is possible under certain conditions. Herein, we report a case of prolonged fever in a patient living in the countryside of Egypt with no reported travel history following accidental blood exposure to a malaria patient. The purpose is to shed light on this rare mode of malaria transmission and also to alert physicians and infectious disease specialists to consider malaria in the differential diagnosis in case of contact history to the blood of a malaria patient.

The pattern synthesis of antenna arrays is a substantial factor that can enhance the effectiveness and validity of a wireless communication system. This work proposes an advanced marine predator algorithm (AMPA) to synthesize the beam patterns of a non-uniform circular antenna array (CAA). The AMPA utilizes an adaptive velocity update mechanism with a chaotic sequence parameter to improve the exploration and exploitation capability of the algorithm. The MPA structure is simplified and upgraded to overcome being stuck in the local optimum. The AMPA is employed for the joint optimization of amplitude current and inter-element spacing to suppress the peak sidelobe level (SLL) of 8-element, 10-element, 12-element, and 18-element CAAs, taking into consideration the mutual coupling effects. The results show that it attains better performances in relation to SLL suppression and convergence rate, in comparison with some other algorithms for the optimization case.
