The first case in Nairobi was reported 12-15 weeks ago. Since then, a lockdown was announced soon thereafter and has been in effect for about 3 months. If each sick person spread the virus to three more people every week, then the virus must have run its full course in Nairobi by now. 1x4>12 = 16M. Uhuru's decision to reopen Nairobi may have be backed by scientific models. In my opinion, if you lived within the Nairobi area under lockdown, odds are high that you contracted the virus and recovered, or have it currently and recovering unknowingly. That's my jua kali class 3 arithmetic.
