It was another busy few days for this novel coronavirus, as the city of San Diego declared a public health emergency, a second cruise ship reported a positive test, and the African continent reported its first case of the virus.

Two more deaths were reported outside China -- one from Japan with no travel history to China, and a Chinese tourist in France, the World Health Organization (WHO) reported. As of Monday, the WHO cited 794 confirmed cases outside China, and three deaths. Latest data indicate that as of Tuesday morning, there are 73,336 cases worldwide.

In an unusual move on Friday, San Diego declared a local emergency and its own public health emergency, NBC San Diego reported. In addition to seven persons under investigation at the Marine Corps Air Station Miramar quarantine -- four of whom have pending test results -- they cited a high number of potential cases, including:

Seven San Diego County residents (two who are awaiting results)

Four non-residents (two awaiting results)

171 individuals returning from China with no symptoms (123 still under self-monitoring)

13 San Diego residents who are close contacts of cases (four of whom are still being monitored)

Two people in U.S. Immigration and Customs Enforcement custody, whose tests are pending

Of the two confirmed cases in isolation from MCAS Miramar, one is "doing well and one is in fair condition," according to UC San Diego Health.

On Saturday, an American woman, age 83, from a second cruise ship, the MS Westerdam, tested positive for the virus in Malaysia, the first person from this ship to test positive, according to Reuters. As widely reported last week, the ship was turned away by several countries before finally being allowed to dock in Cambodia after declaring there were no cases of coronavirus on board.

Reuters noted that "the cruise ship operator has sought more tests" to confirm this case, and added that as of Sunday, her husband tested negative.

Further afield, on Sunday the WHO announced the first case of the virus in Africa. The patient was described as an "asymptomatic" contact of a travel-associated index case. The WHO noted that other contacts of the confirmed case are under investigation, though none have tested positive.

Spread of COVID-19 to under-resourced areas has been a prime concern for the WHO, which held a press briefing on Monday, reiterating that they are sending personal protective equipment to many countries, working with manufacturers to ensure supply, and training health workers to ensure all countries are prepared for cases.

But Michael Ryan, MD, executive director of WHO's health emergencies program, cautioned against using the word "pandemic" just yet. That may be up for discussion when there is ample evidence of "efficient community transmission outside China," but as of now, the majority of cases have a direct link back to China, he noted.

"We need to be extremely cautious about using the word pandemic," Ryan said. "Of the transmission that has occurred, the majority ... can be traced through existing transmission chains. We have to be careful not to drive fear in the world right now."
