After the human body becomes infected with the HIV virus, 50%-70% of people may exhibit symptoms similar to the common cold, such as fever, headache, sore throat, and muscle and joint pain, about two weeks later. There can also be generalized swelling of the lymph nodes, the appearance of maculopapular rashes, and symptoms such as nausea, vomiting, and diarrhea. Generally, these symptoms will disappear after about a month, and then a symptom-free infection period follows, which can last from 1 to 10 years. Subsequently, the individual enters the AIDS phase. During the AIDS phase, various types of infections erupt, including bacterial, viral, fungal, and parasitic infections, and even concurrent malignant tumors, all of which can lead to death.

Does AIDS cause headaches?

People with AIDS may experience headaches. This can occur when individuals with AIDS develop fevers due to opportunistic infections, leading to an increase in body temperature which may cause cerebral blood vessel dilation and result in headaches. Additionally, some AIDS patients may also have intracranial opportunistic infections, such as infections with Toxoplasma, Cryptococcus, and Tuberculosis, which can cause serious meningitis or encephalitis, leading to severe and intense headaches accompanied by fever. These conditions are very dangerous and require prompt diagnosis and treatment.

AIDS is divided into several stages.

AIDS is clinically divided into four stages: acute infection, asymptomatic infection, pre-AIDS stage, and AIDS stage. The acute infection stage refers to the period starting about half a month after the human body is infected with HIV, during which symptoms similar to the common cold appear, and these symptoms generally disappear after a month. Around two months, HIV antibodies can appear in the human body, at which point these antibodies can be detected through blood testing. Thereafter, the individual enters the asymptomatic infection stage, which typically lasts 7-8 years, though some people may reach 10 years. Afterwards, the pre-AIDS stage begins due to the decline in immune function, with symptoms such as fatigue, night sweats, and weight loss appearing, eventually progressing to the AIDS stage.

What are the symptoms of AIDS?

The primary symptoms of AIDS are mainly due to immunodeficiency and opportunistic infections caused by a weakened immune system. During the acute phase of AIDS, the virus replicates in large numbers, leading to immune damage and disorder. In the acute phase, symptoms such as rashes, fever, sore throat, weight loss, and diarrhea are common. During the symptomatic phase, symptoms like unexplained fever, diarrhea, chest tightness, coughing, phlegm, and numerous white secretions on the oral tongue are commonly observed.

AIDS diarrhea several times a day

After HIV-infected individuals enter the AIDS phase, due to the severe deficiency in human immune function, viruses, bacteria, fungi, parasites, and malignant tumors can invade the human digestive system, leading to diarrhea. This diarrhea can occur 3-5 times daily, or even up to 10 times, and it can persist for more than one month.

Does blistering at the base of the tongue indicate AIDS?

It is unscientific and inaccurate to judge whether someone has HIV solely based on bubbles at the base of the tongue. To correctly determine if someone has HIV, we need to consider the medical history, whether there has been exposure to the HIV virus, whether screening tests have been conducted, and whether confirmatory tests have been carried out. Only by considering these factors can we accurately determine whether someone has HIV.
