These migrants are all men, three Syrians and the others all Tunisians.
In 2020, many people wanted to leave the Tunisia clandestinely. According to the High Commission for United Nations for refugees (UNHCR), around 12,000 Tunisians arrived in Italy. This year 2021, of the 3,800 migrants disembarked in Italy between January 1 and February 21, 1,000 arrived from Tunisia and 2,500 Libya.

When will the US reach herd immunity and what will it look like?
(CNN)A year into the Covid-19 pandemic, it appears that trends have finally shifted in a positive direction.
New cases, hospitalizations and deaths are dropping rapidly, and the supply of available vaccine is growing. The country could be well on its way to herd immunity, the point at which enough people are protected against a disease that it cannot spread through the population.There's still so much to learn about Covid-19. But if you had to put a number on it, what level of population protection is required to reach herd immunity against Covid-19?
Casadevall: I am in the 65-80% range. We all expect that this virus is not different from other viruses and that we will reach a point that a sufficient number of people are immune so that the virus cannot jump any more. It reaches a point that there are so few hosts, so few people that it can jump to, that the epidemic crashes. The number of cases is the threat, and in the declining curve, we see that the number of people it can jump to is dropping.
Individuals who have already had Covid-19 may have some natural immunity after infection. Can we count those people toward herd immunity? Casadevall: Yes. The number of people known to have reinfection is very low. There have definitely been some cases, and they've been documented. But despite all this virus still floating around, people are not getting sick again, and to me that's really encouraging
New variants potentially threaten levels of protection, both in terms of vaccine efficacy and possible reinfection. How much does this threat cut into measures of progress to herd immunity? Casadevall: Variants are the big threat on the horizon. They have the potential to derail things, but I stress potential. We know variants are out there, but there are still very few cases of documented reinfection. What that suggests to me is that variants are not evading immune defense. The most encouraging thing to me is how rapidly that curve is coming down. It gives me hope that we're going to crash the curve before variants become a threat.
Some surveys still show a significant amount of vaccine hesitancy. How will this affect the path to herd immunity? Casadevall: The number of cases is the threat, and a lot depends on what the vaccine uptake is by next year. The more cases you have, the more virus replication and the more likelihood that a person can be infected. If we keep going the way we are and crash the curve, the likelihood of a bad scenario is reduced. Malaty Rivera: Anti-vax people are a loud minority. They don't represent a large group of people in this country, and I don't think they'll have tremendous victory when it comes to things like herd immunity. Usually, the impediment to people not taking a vaccine is understanding, but we've had major wins with campaigns to address this. Mehta: It's really understandable why some people in our communities may have hesitation around the vaccine. What we need to do is continue to do a good job caring for them and being role models, not only by sharing knowledge and taking the vaccine ourselves, but continuing to take precautionary measures such as wearing a mask and practicing good hand hygiene. Murray: If we can move from 25% of the population not being vaccinated to 10%, that really boosts herd immunity way up. Even if variants aren't as bad as we fear, it's still going to be pretty close and vaccinating over the tipping point would make a huge difference. What's the bottom line? Generally, when can we expect a return to normal? Casadevall: No one in this world can tell you what percent of protection is needed or what date it will happen by. My gut is positive, and I do think 2021 is going to be a better year than 2020. Assuming we don't have a variant that forces new lockdowns, I think the second half of this year will look different. We may lift restrictions in the fall, or maybe a little earlier if the rapid decline continues and the curve stays down. Get CNN Healths weekly newsletter

Lessler: When we get to very, very low numbers of new cases, that's going to be the sign that things can be fine. As we step back control measures, we should do so slowly and deliberately and watch for any resurgence. Some of this comes down to deciding what is normal, because the fact of the matter is we need to accept the fact that we will be living with this virus forever. It will come back again and again like the flu, but that doesn't mean that it will always be the scourge that it is now. Malaty Rivera: Vaccinating 70% of the population is going to be an absolute game changer for us in terms of getting back to what we could do similar to pre-Covid days. I'm optimistic that this fall is going to look very different, and hope that means things like travel and mask-free socializing with loved ones. We're on the road to getting there if we keep the trends down.
