Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
After tests in California, the total number of Coronavirus cases was recorded as 2000 positive cases on a particular day. The number of cases increased by 500 on the second day, with 50 recoveries. On the third day, the total number of new cases spiked to 1500 with 200 recoveries. What's the total number of positive cases after the third day?

### Response:
 Ikiwa siku ya kwanza idadi ya visa vya Corona ilirekodiwa kuwa 2000, na visa vipya 500 siku ya pili, idadi jumla ya visa iliongezeka hadi 2000+500 = <<2000+500=2500>>2500
Kwa kupona kwa visa 50 siku ya pili, idadi jumla ya visa ilipungua hadi 2500-50 = 2450.
Siku ya tatu, visa vipya vilikuwa 1500, na jumla ya 1500+2450 = <<1500+2450=3950>>3950
Ikiwa kulikuwa na kupona kwa visa 200 siku ya tatu, idadi jumla ya visa ilipungua hadi 3950-200 = 3750 visa.
