Hi welcome to health care magic forum.
HIV transmission is generally rare if there was short and single intercourse,but of course it is possible especially if there was sex worker and unprotected sex. soi I suggest to do tests as soon as you can. those signs are common and in most cases it indicates some other more common infecdtious disease,but in some cases it can be part of ARS so again, you should do HIV test
Hope I have answered your query.Wish you good health. Regards
