Coronavirus: Italy’s South Tyrol begins 3-day mass testing programme

Local health authorities have organised mass screening for the coronavirus in South Tyrol, hoping to test up to 70 percent of the population.

Mass screening began at 8am on Friday as the north-eastern region hopes to subject 70 percent of the population, or some 350,000 people, to rapid swab tests.

The testing programme was announced ahead of the planned reopening of primary schools and preschools in the area on Tuesday.
 
 
The mainly German-speaking province in northern Italy, said infection rates had “reached such proportions” to make testing 350,000 people key to quickly rooting out virus spreaders.
 
By 10am authorities had tested more than 24,000 people and found 596 positive for Covid-19.
 
The rapid tests are available on Friday, Saturday and Sunday between 8am-6pm. Testing sites have reportedly been set up at 200 locations, in every municipality. Testing is voluntary and free.
 
Many of the testing centres have been set up in buildings normally used as polling stations, Italian news agency Ansa reports, and there were long queues forming outside some on Friday morning.
 
In the city of Bolzano, residents from each street are given 'time windows' during which to participate.
 
 
South Tyrol, also known as the autonomous province of Bolzano, is currently classified as a red zone under Italy's regional tier system of coronavirus restrictions.
 
Regions can implement their own coronavirus restrictions in addition to those set by the government, and every region has its own rules on testing due to Italy's highly decentralisation system.
 
While Italian authorities maintain that widespread screening of the population is key to controlling the coronvirus outbreak in the country, some experts have cast doubt on the effectiveness of the rapid tests, first used in Italy at airports this summer.

Q&A: What you need to know about Italy’s West Nile virus outbreak

As Italy records a surge in cases of West Nile fever, we look at what the disease is and where in the country it's spreading.

Q&A: What you need to know about Italy's West Nile virus outbreak

Mosquitos are unfortunately one downside of summer in Italy. But as well as being a nuisance, they may also pose a health risk in the country – one of the few in Europe to record cases of West Nile virus (WNV)

Last week Italy recorded 50 more cases of the mosquito-borne virus, bringing the total number of infections to 144 according to the latest report from Italy’s Higher Health Institute (ISS).

This marked a 53-percent increase in cases against the previous week, while ten people have died so far.

As the number of infections continues to rise, here are the answers to the most pressing questions about the disease and the outbreak in Italy.

What is it?

The West Nile Virus (WNV) is a single-stranded RNA virus that can cause West Nile fever in humans.

It’s a member of the Flavivirus family together with other endemic viruses such as the Zika and Dengue viruses.

The virus was first identified in 1937 in Uganda’s West Nile district but has since spread to many other parts of the world, to the point that it is now considered indigenous to Africa, the Middle East, Asia and Australia. 

Carried by birds, West Nile virus is transmitted to humans by mosquitoes.

The West Nile virus is primarily transmitted by mosquitoes of the Culex species, which infect humans and other mammals through their bite, according to Italy’s health ministry.

There is no evidence that human-to-human transmission is possible.

Where are cases being reported in Italy?

Infections have been largely concentrated in the north of the country, especially in the Veneto region, where six people have now died of the disease. Other deaths were recorded in Lombardy, Piedmont and Emilia-Romagna.

The city of Padua, which is located in Veneto’s mainland, around 35 kilometres away from the Adriatic coast, is currently regarded as the hotspot of the virus. 

It isn’t yet clear why Veneto has been the worst-hit region so far, but experts fear that its marshy lowlands might be the perfect breeding ground for disease-carrying mosquitoes.

How severe is the outbreak in Italy?

West Nile virus is not new to Italy. However, this summer has brought the highest number of cases recorded yet.

National infection levels remain relatively low but the country has by far the largest number of cases in Europe.

According to the most recent report from the European Centre for Disease Prevention and Control (ECDC), dated August 3rd, 94 out of 120 recorded cases were in Italy.

Greece had 23 reported cases. Romania and Slovakia had two and one respectively. 

Italy is the only European country that has reported fatalities.

What are the symptoms?

According to the Italian Higher Health Institute (ISS), around 80 percent of infected people show no symptoms whatsoever.

In symptomatic cases, however, symptoms generally resemble those of a common flu and include fever, headaches, nausea and diarrhoea. 

The infection is usually only dangerous for people with weakened immune systems such as the elderly, and the most severe symptoms occur in fewer than one percent of infected people.

In healthy people, the virus is unlikely to cause more than a headache or sore throat, and symptoms generally last only a few days.

According to the data currently available, around one in 150 infected people can show symptoms as serious as partial vision loss, convulsions and paralysis. 

In very rare cases (around 0.1 percent, or one in 1000) the disease can cause brain infections (encephalitis or meningitis) which may eventually be fatal.

Is there a cure?

There is no vaccine against West Nile fever. “Currently vaccines are being studied, but for the moment prevention consists mainly in reducing exposure to mosquito bites,” the ISS states.

There is also no specific treatment for the disease caused by the virus.

Patients showing the more serious symptoms are usually admitted to hospital and treated with IV fluids and assisted ventilation.

What should you do to protect yourself?

Seeing as there is currently no vaccine against the virus, the best way to protect oneself is by reducing exposure to mosquitoes as much as possible.

Italian health authorities have listed a number of official recommendations to help residents avoid mosquito bites. These include: 

  • Use repellent
  • Wear long-sleeved shirts and long trousers when being outdoors and especially during ​​mosquitoes’ peak activity times, i.e. sunrise and sunset
  • Use mosquito nets on your windows or sleep in rooms with air-conditioning and keep the windows closed
  • Make sure there are no pools of stagnant water around your house
