Cronologia
- Nel 1981 viene riconosciuta l’esistenza di
una nuova malattia che in realtà esisteva
già da molti anni. Scambiata per altro.
- Nel 1982 alcuni primi casi tra gli
emofilici, obbligati a ricevere
trasfusioni di plasma.
- Nel 1983 i dati sull’infezione
Individuano 642 omosessuali,
154 tossicodipendenti, 50 haitiani
Il virus HIV
• Nel 1983 all’Istituto
Pasteur a Parigi i
ricercatori vedono il virus
al microscopio (Barré Sinoussi/Montagnier)
• L’anno dopo i CDC in Usa
annunciano di aver isolato
a loro volta il virus (Gallo).
• Il virus è lo stesso e inizia
una battaglia legale per la
rivendicazione della
scoperta.
I primi casi celebri
• A metà degli anni
Ottanta l’epidemia si
diffonde.
• Entra nella sua terza
fase: non è più solo
legata a gay, emofilici,
tossicodipendenti.
• Nel 1985 si tiene ad
Atlanta la prima
conferenza
internazionale
sull’AIDS.
AZT: la speranza
Nel 1987 a tempo di
record fu approvato un
primo farmaco, inibitore
della transcrittasi inversa,
per la cura dell’infezione.
Nel 1988 viene istituita la
Giornata mondiale
dell’AIDS: il 1 dicembre.
Manifestazioni alla
Conferenza Mondiale a
Montreal perché si abbassi
il prezzo di Azt.
“AIDS: se lo conosci lo eviti”
• Nel 1989 primi spot
pubblicitari in Italia per
informare sul rischio: si
insiste su
tossicodipendenti e
rapporti sessuali non
protetti.
• Nel 1990 alla Conferenza
internazionale a San
Francisco sull’AIDS
manifestazioni contro le
norme restrittive di G.W.
Bush per i sieropositivi.
La svolta
• Nel 1996 la svolta: si
abbandona la monoterapia
con Azt: nuovi studi clinici
dimostrano l’efficacia
della Haart (Highly Active
Antiretroviral Therapy) che
combina due inibitori della
transcrittasi inversa con un
inibitore della proteasi. La
triterapia diventa standard
mondiale per la cura
dell’Aids. (David Ho)

Prevalenza stimata di Hiv nei giovani adulti (15-19
anni)
per nazione
In Italia: le infezioni non si fermano
• Dati dell’Istituto Superiore di Sanità dicono
che, nel 2015, sono state segnalate 3.444
nuove diagnosi di infezione da Hiv: pari a 5,7
nuovi casi per 100.000 residenti. I casi di Aids
registrati 789.
• L’Italia è per incidenza al tredicesimo posto
tra le nazioni dell’UE. Le regioni con
l’incidenza più alta sono Lazio, Lombardia
(20mila persone sieropositive), Liguria, EmiliaRomagna.
E ancora…..
• Le persone che hanno scoperto di avere l’Hiv
nel 2015 erano maschi nel 77,4% dei casi.
• L’età mediana 39 anni per lui e 36 anni per lei.
• L’incidenza più alta è tra le persone di 25-29
anni.
• La modalità di trasmissione: aumentano i casi
attribuibili a rapporti sessuali non protetti
• Nel 2015 i casi attribuiti a trasmissione
eterosessuale sono stati il 44,9 %.
Sieropositivo ma
non sa di esserlo
Si stima che nel
mondo solo la metà
delle persone con
Hiv sanno di essere
sieropositiva.
In Italia il 25 per
cento delle
persone con
l’infezione da Hiv è
consapevole del
proprio stato

Sommario
Quattro sieropositivi su dieci lo nascondono
