The most recent thing I check was travel options. Clearly the best option is to stay at home. If you travel, focus on remote and outdoor locations, and avoid public transport and crowded areas. If you must travel, or want to travel for a holiday, remember:-
Always wear a mask on any form of public transport and in transport hubs
The risks increase rapidly with the size of your 'holiday' population (e.g. in a large resort hotel, etc.)
The more varied your 'holiday' population (e.g. people coming from many places, etc.) the higher the risk
Indoor gatherings involve a higher risk than outdoor gatherings
If you stay in a hotel look for ways to reduce contact with others, e.g. take meals in your room, etc.
Interestingly, there is no evidence that handling food or eating is associated with directly spreading Covid-19, but avoid touching food, packaging, and utensils, and prefer places that serve food and avoid buffets, salad bars, and drink stations
Air travel involves waiting in line with people and touching a lot of different surfaces, but viruses and germs don't spread easily inside aircraft because of the way air circulates and is filtered
Prefer flights with blocked middle seats and where passengers must always wear masks, however Covid-19 transmission on planes is considered low
Advice is don't remove masks and don't eat and drink on planes, carry lots of disinfecting wipes, and wear a face screen when boarding and deplaning
When driving, stops for fuel, food, and bathroom breaks increases the risk of contamination (when outside the car always wear a mask and gloves and dump them before entering the car)
Travelling by car is the safest option, in part because you don't travel with other people (i.e. don't share breathing space) and in part because you control better the scope for contamination
Always use hotels that have high levels of Covid-19 safety procedures, but evidence so far is that hotels and motels don't present a high risk
The reality is that Covid-19 risks associated with any form of travelling are considered lower than the risk of a road accident
After travelling, take extra precautions for 14 days, and get tested.
I found it useful to check the 'travel corridors' on the UK government website, which list the places that that you can return from without having to self-isolate back at home (i.e. places that have a lower risk than your home location).
The World Health Organisation has a Coronavirus (COVID-19) Pandemic website, and a dashboard with the latest confirmed cases, new cases, and deaths around the world. They also issue daily 'situation reports'.
One of the most impressive national efforts concerning prevention, detection, and documentation of COVID-19 is in Iceland. They have a multi-lingual website and have tested more citizens per capita than any other country in the world. Possibly the most important result is "about half of all those who tested positive are non-symptomatic" (i.e. asymptomatic). That means that they do not have symptoms, would usually not be in self-quarantine, but could still be spreading the virus. Previous to this data there were no reliable studies on the percentage of asymptotics, i.e. figures ranged for 5% to 80%.
Other useful source of information include:-
The US Centres for Disease Control and Prevention, which has a 'Situation Summary'.
The European Centre for Disease Prevention and Control has a webpage dedicated to COVID-19.
The UK has a "what you need to know" webpage, and the French government has a Coronavirus information webpage. Every other European country also has a dedicated COVID-19 website, e.g. Luxembourg has a website COVID-19 in English.
Johns Hopkins provides an up-to-date guide to the Coronavirus COVID-19.
The Pharmaceutical Journal provides "Everything you should know about the coronavirus outbreak" and they have a Coronavirus (COVID-19) webpage with information updated daily.
The Lancet hosts a COVIS-19 Resource Centre, and Nature has the COVID-19 Watch.
Oxford University hosts the Centre for Evidence-Based Medicine, which has a specific Oxford COVID-19 Evidence Service.
In addition Google publishes the COVID-19 Community Mobility Reports.
World Mapper provides a 'Chronology of a Pandemic', which includes a map animation showing how the virus spread across the world.
Finally several publications make reference to the long-term leadership that the 'One Health Commission' could provided. They are trying to address the fact that nearly 75% of all emerging human infectious diseases in the past three decades originated in animals.
