Answer:
The inability of the sinuses to drain and the associated lack of airflow create an environment that is ideal for bacterial growth. In acute viral sinusitis, the virus that caused the upper respiratory infection has infected the sinuses and continues to produce mucus, inflammation, and congestion.
Sorry its a very long answer-
1.) Failure to maintain the rule of law
The government's repeated failures to bring levels of violent crime under control contributed to an environment which saw people resort to violence without fear of arrest or successful prosecution.
2.) Border control
3.) Corruption
4.) Employment
5.) Education
This has been government's biggest failure and carries much of the blame for the high unemployment levels. It is arguable whether current state education is in its totality any better than that under apartheid. Only 1% of black matriculants achieve a good HG maths pass.
The education system is a good example where policy failures in one area compounded those in another.
6.) Slowing economic growth
7.) Foreign policy
8.) Service delivery
9.) Race relations
Through diffusion is the answer
