Texas joined California and New York to register more than 400,000 cases.

Our colleagues at the Visual and Data Journalism Team have been tracking the pandemic in the US and around the world.
HK hospitals 'risk collapse' as cases spikeHong Kong's hospital system could face "collapse" as it grapples with a sharp rise in coronavirus cases, the city's leader Carrie Lam has warned.
She urged residents to stay indoors, saying the city was "on the verge of a large-scale community outbreak". New measures were introduced on Wednesday including mandatory face masks and the closure of dine-in restaurants.
Less than a month ago the average number of new daily cases in Hong Kong was fewer than 10 but the city is now regularly reporting more than 100 new infections every day. A record 145 cases were recorded on Monday.
On Tuesday the city reported its 23rd overall death. The patient had been a resident at a care home where at least 45 infections have been recorded.
Airport tests needed to avoid 'cliff-edge' in UK travel industryAs the UK faces criticism from Spain for reintroducing quarantine measures, Heathrow Airport chief executive John Holland-Kaye says the restrictions have already caused "a few more drop-outs" among people with flights booked.
He told BBC Radio 4's Today programme that the government needed to introduce an "alternative to the cliff-edge" of quarantine for free travel and said a testing system could be "up and running within the next couple of weeks".
He said it would likely involve people quarantining for eight days rather than 14, after which they could leave if they received a negative test result. Other countries such as France are testing similar approaches, Holland-Kaye said.
"We all have the same interests here. Nobody wants to have a second wave. We will always put the interests of health and safety first. But the government also has a responsibility to protect jobs and support the economy," he said.
The airport boss said that unless the country can find a "balance" between safety and getting the economy moving, the UK could face "a huge jobs epidemic" as well as a viral one.
Trump sticks by discredited use of hydroxychloroquineMore now from the US where President Donald Trump has again touted the anti-malarial drug hydroxychloroquine as a way to prevent coronavirus, contradicting the advice of his own public health officials.
At a White House news conference on Tuesday he said the drug had only been rejected as a Covid-19 treatment because he suggested it. Scientists say there is no evidence the drug can fight the virus, and regulators warn it may cause heart problems.
"When I recommend something, they like to say 'don't use it'," he told reporters. Trump also grumbled that the top US infectious diseases expert, Dr Anthony Fauci, was more popular than him.
Earlier this week, President Trump and his son, Donald Trump Jr, both shared a video on social media advocating hydroxychloroquine. Facebook and Twitter removed the content, flagging it as misinformation.
UK orders fourth potential vaccine with 60 million dosesThe UK government has signed a fourth coronavirus vaccine deal, securing up to 60 million doses of an experimental treatment being developed by drug giants GSK and Sanofi.
Regulatory approval could be achieved by the first half of 2021 if trials are successful, according to Sanofi, which is leading the vaccine's clinical development.
The government has already signed up for 100 million doses of the Oxford University vaccine being developed by AstraZeneca .
It has also secured another 90 million doses of two other promising vaccines .
However, it is still uncertain which - if any - of the vaccines will work.
