No antibiotics¹ have been proved to be 100% effective in treating SARS so far. The only effective way to get rid of it is by ourselves. It likes a prolonged battle between the viruses and our immune response. In fact, viruses couldn’t kill all the immune cells in a health individual. The stronger the immune function you have, the less the viral injury you get. Therefore, the degree of sickness after infection and the rate of recovery mainly depend on how strong your immune function is.
You cannot avoid the infection unless you avoid from those infected individuals/area. But, you can try your best to boost up your immune function by several regimes. Make sure you are "extremely healthy" at least during this critical period. Stronger immune function could keep the viral damage minimal² even you were so unluckily being infected. Also, stronger immune function delays the onset³ of any detrimental⁴ effects from the viral infection. Scientists are now working on tracking the treatment and so make sure you are still surviving until an effective treatment occurs. 177
