Kulingana na Ripota Wetu, Wanasayansi wamegundua ni kwa nini baadhi ya watu hawapati maambukizi ya VVU licha ya kujipata katika mazingira hayo mara kwa mara.
Kwanza, baadhi ya kiasili hutokeza viwango vya juu vya saitokini za kinga ambazo huzuia virusi kuingia kwenye seli. Wengine wana majibu yenye nguvu ya kinga ambayo huharibu haraka VVU kabla ya kuenea.
Sababu maarufu zaidi ni mabadiliko ya nadra ya jeni yanayoitwa CCR5-Δ32, ambayo hufunga mlango mkuu wa kuingia kwa virusi kwenye seli zinazopatikana zaidi katika Wazungu.
Hatimaye, baadhi wana idadi kubwa ya seli T-killer ambazo hufuta seli zilizoambukizwa mapema. Kumbuka, haya ni matukio ya nadra, kwa hivyo kila wakati fanya ngono salama na upimaji wa mara kwa mara ili ubaki salama.

According to Our Reporter, Scientists have discovered why a tiny group of people resist HIV infection despite repeated exposure.
First, some naturally produce high levels of protective cytokines that block the virus from entering cells. Others have super-strong immune responses that quickly destroy HIV before it spreads.
The most famous reason is a rare genetic mutation called CCR5-Δ32, which shuts the virus’s main entry door into cells mostly found in Europeans.
Lastly, some have high numbers of killer T-cells that wipe out infected cells early. Remember, these are rare cases, so always practice safe sex and regular testing to stay protected.
