Dear Editor, Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a strain of coronavirus that causes COVID-19 that was first identified in Wuhan of, China, on 2019 (Coronaviridae Study Group of the International Committee on Taxonomy of Viruses, 2020).

(BA) is a disorder of neovascular proliferation originally described involving skin and regional lymph nodes of HIV infected person (1,2). It has been demonstrated to involve a variety of internal organs, including liver, spleen, bone, brain, lung, bowel and uterine cervix (3-5) and to occur in other immunocompromised patients as well as immunocompetent hosts (6,7). (BA)rtonella quintuna and B. henselae have been shown to be a cause of (BA), both by direct culture (8).

(BA)(BA) Fighani Shirazi (925AH/1519AD) is one of the epoch maker poets of the Persian literature. Effect of Fighani on poets and poetic trends of Safavid period (907-1135 AH/1501-1722 AD) is remarkable. In biographies of this period, names of many poets have been mentioned who were researchers of Fighani and answered his sonnets by sonnet such as zamiri Isfahani (987 AH/1579-80 AD) and Huzuri Qomi (1000 AH). Many others have been impressed by him and have followed his method such as sa‘ib Tabrizi (1087 AH/1676-77 AD) and ’Urfi Shirazi (999 AH/1590-91 AD).In addition, some issues have been referred in these works which attract attention of the reader. For example, ''Mardum Didih'' (written in 1175 AH/1761-2 AD) refers to imitation of Fighani by Siraj al-din Alikhan Arizu and importance of this issue is made evident when we know that Kh an Arizu is one of the greatest critics of Persian classic literature and is rarely found among the old and his special attention to a poet such as Fighani indicates his importance in Persian literature. Valih Daghistani (1170 AH/1756-7 AD), the writer of Riyaz al-Shu’ara (written in 1161 AH/1748 AD), states that he is indebted to Fighani in learning poetic techniques and poetic language. Imitation and emulation of Fighani in centuries 10 AH/16 AD and 11 AH/17 AD were so common that some of the poets such as ’Urfi Shirazi (999 AH/1590-91 AD) gathered in shop of a person called Mir Tarzi-Afshar and imitated work (Divan) of Fighani.
