Is it good to check AIDS to hospitals or CDC?
Do HIV testing, in hospitals and centers for disease control can, but determine the diagnosis needs to go to the Centers for disease control or designated infectious disease hospital
At present, there is no effective vaccine to prevent AIDS, so the most important thing is to take preventive measures. The methods are as follows:1. Keep clean, do not engage in prostitution and whoring, and avoid high-risk sexual behaviors
It is forbidden to take drugs and share syringes with others Blood transfusion and blood procts should not be used without authorization, but should be used under the guidance of doctors Do not use or share toothbrush, razor, razor and other personal procts Using condom is one of the most effective measures to prevent STD and AIDS in sexual life It is necessary to avoid direct contact with the blood, semen and milk of AIDS patients and cut off the route of transmission 
extended data:
in the world, there is a popular concept that "testing is intervention", HIV testing is an effective means to enhance public awareness of protection, similar to regular physical examination is concive to enhance people's health awareness
ZHENG Zhiwei, President of Beijing STD / AIDS Prevention Association, said that to let the public participate in HIV testing, on the one hand, we hope that they can learn more about relevant knowledge and examine their own behaviors in the process of experiencing HIV testing; On the other hand, the detection can find the infection cases in time, rece the risk of transmission, and effectively prevent AIDS

there are two cases when the hub center hole size is not correct:
(1) if it is large, the ring diameter can be changed
(2) if it is small, it can only be replaced
-
the following five parameters should be paid attention to when replacing the wheel hub:
(1) center hole diameter
refers to the size of the center hole of the wheel hub. Although the wheel hub which is different from the original factory value can be installed through the positioner, it is not recommended for safety reasons
(2) pitch circle diameter
for example, a hub with a pitch circle diameter of 5x120mm has five positioning bolts, which form a circle with a diameter of 120mm
(3) offset
is also called et value. If the value is positive, it means that the hub fixed surface is outside the central plane, otherwise it is inside the central plane. Generally, the offset value of a car is positive, which has a great influence on the driving stability and the tracking performance of the car
(4) diameter
diameter determines the size of the wheel rim. Because the car's speedometer reading is measured according to the wheel speed, the wheel diameter is too large, resulting in the speedometer reading is too small, unconsciously, you will exceed the speed limit. Excessive wheel diameter will also rub and hang to the wheel arch and fender. Therefore, it is better to upgrade the wheel hub to be 1 inch larger than the original one, no more than 2 inches at most, and to match the thin tire to ensure that the size of the whole wheel is similar to that before upgrading
(5) width
width affects which kind of tire to choose after upgrading. Too wide tire will rece the starting speed and consume more fuel. Common values correspond to: 185mm wide tire corresponds to 5-inch wide rim, 195mm corresponds to 6-inch, 205mm corresponds to 6.5-inch, 215 corresponds to 7-inch< br />
