RESUMEN
Objective To analyze the changes of HIV‐1 viral load and virological efficacy of treatment effects for AIDS patients treated with antiretroviral therapy from 2009 to 2014 in Lincang City .Methods Monitored the HIV‐1 viral load for 13 491 cases of AIDS patients treated with highly active antiretroviral therapy(HAART) from 2009-2014 in Lincang City of Yunnan and analyze the monitoring data .If the patients had treated with HAART were still with viral load greater than 1 000 copy/mL ,the treatment was defined as a failed treatment or a virological failure .Results The total rate of virological failure was 14 .34% (1 935/13 491) . The rate of virological failure of children group was 15 .53% (50/322) ,and of adults group was 14 .31% (1 885/13 169) .There was no statistically significant difference between childeren and adults(χ2 =0 .38 ,P>0 .38) .The rate of virological failure in males was 16 .34% (1 156/7 076) ,and 12 .14% (779/6 415) in females ,the difference was statistically significant between men and female (χ2 =48 .16 ,P<0 .01) .Conclusion Antiretroviral treatment can delay the disease progression and improve the life quality .
