In our series of letters from African journalists, Ismail Einashe writes that migrants are facing a tougher time since the outbreak of coronavirus.
Thousands of African migrants are stuck in transit - unable to reach their destination or to get back home because the coronavirus pandemic has caused the world to come to a standstill.
Take two key exit points: the Horn of Africa route via the Gulf of Aden into the Middle East and the central Mediterranean route from Libya to Europe.
On the Horn of Africa route, the UN agency, the International Organisation for Migration (IOM), has recorded a sharp fall in the numbers of migrant crossings.
In April just 1,725 migrants arrived in Yemen from the Horn, compared to 7,223 in March, 9,624 in February and 11,101 in January of this year.
Last year more than 138,000 people - an average of around 11,500 a month - crossed on boats to Yemen, the majority Ethiopians bound for Saudi Arabia in search of work.
In the Somali port of Bosaso, migrants bound for the Middle East have been left stranded.
'Coronavirus has changed everything'
The IOM estimates that about 400 migrants are currently been hosted by members of the local Ethiopian community in informal settlements around the city but the agency says they face increased stigma and abuse because travellers are seen as carriers of the virus.
A 19-year-old migrant told IOM: "I have been here for around three months. The coronavirus has changed everything. I cannot continue. I cannot go back because all borders are closed."
In Djibouti, hundreds of migrants have been abandoned by traffickers in a country with one of the worst coronavirus outbreaks in Africa.
Meanwhile, across the Red Sea in Saudi Arabia and the United Arab Emirates have deported nearly 3,000 Ethiopian migrants on cargo planes over suspicions that they have coronavirus.
Most of them are domestic workers - including maids - who worked legally for low pay in the oil-rich Arab states.
There is likely to be a sharp rise in attempts to migrate to Europe once travel restrictions are lifted, not least because lockdowns have worsened poverty in Africa'
In Libya - the other key exit point, and the most dangerous sea crossing for migrants in the world - restrictions have prevented humanitarian boats from rescuing migrants stranded at sea - with migrants forced to return to a country mired in a dangerous conflict.
There is likely to be a sharp rise in attempts to migrate to Europe once travel restrictions are lifted - not least because lockdowns in African states have worsened poverty and have caused more damage to already struggling economies.
As for European states, they have used the Covid-19 pandemic to once again politicise the issue of migration.
Malta has closed its ports and returned migrants at sea to Libya, while Italy said migrants would be quarantined on rescue boats.
Covid-19 has exposed migrants as the most marginalised people in this pandemic.
The UN High Commission for Refugees (UNHCR) says that of the 167 countries that have fully or partially closed their borders to deal with coronavirus, 57 have not made an exception for those seeking asylum.
The right to claim asylum is a basic right, though in recent years many states have sought to curtail it.
Most African migrants stay in Africa
In Europe, countries such as Austria, with a long track record of harsh anti-migration policies, have frozen the right to asylum using Covid-19 as justification.
Not only have migrant rights been curtailed but also blame is falling on them, with an increase in xenophobia because migrants are framed as carriers of the disease and maligned by politicians and media alike.
In Guangzhou in China, African migrants have been subjugated to evictions, harassment and forced quarantines, because of coronavirus fears, fuelled by a deep well of racism - this has sparked outrage and anger in Africa.
The majority of migration in Africa is intra-continental - Zimbabweans in South Africa, South Sudanese refugees in Uganda to workers from Burkina Faso in Ivory Coast.
South Africa has the highest number of coronavirus cases in Africa and it is also a regional magnet for millions of migrants.
It has been the government's long-standing objective to reduce migration, and it seized the opportunity provided by the pandemic to build a border fence with Zimbabwe.
There is a danger that Covid-19 will do long-term damage to migrant rights, as states continue to adopt inward-looking policies to try and keep out not only people seeking better economic opportunities in Europe, but also those fleeing political persecution.
