The COVID-19 PANDEMIC in USA is plateaued in quite a few states and in USA, THANK for staying home police and warmed up weather. The tasks facing USA in the coming months are big, and may lead to the control, even end of the pandemic in USA.

1.  Cut/control infection from family to family

2. Stay home till the end of May while having minimal workers to keep essential

3. To best use summer to end the pandemic. China controled it in winter. USA cut USA-China air delayed the pandemic in USA for 2 months (2 winter months). Now USA CAN BEST USE SUMMER TO END THE PANDEMIC. Summer starts May 5.

5. Speed up vaccines for November for USA and EU.

6. EXPAND REMDESIVIR testing in 1) USA: 300 patients OPEN-LABEL study in NY (6% current death rate), 200 patients OPEN-LABEL study in MICHIGAN(8% current death rate); 2) EU: 200 patients OPEN-LABEL study in France (17% current death rate).

Make sure your family members wear masks when going out of house for shopping, working, walking. Protect your family members is the essential of protecting yourself. On the other hand, make sure you wear mask when going out of house. Protect yourself is essential of protecting your family members.  Stay home, Stay home, and Stay home. Do not “burn” your family.

Due to the fast progress of coronavirus infection in the acute phase, early diagnosis is paramount. It has been reported that antibodies (IgM, IgG) to COVID-19 only detectable 11, or 12 days later in most patients after infection. Therefore, acute COVID-19 infections would be wrongly diagnosed and not be treated on time.

CONCLUSION:  Anti-COVID-19 antibodies are not suitable markers for acute phase or early diagnosis of coronavirus infection. These anti-COVID-19 antibody assays may be good for vaccine development, assessing immune status to coronavirus.

Hawaii and Puerto Rico are tropic areas of USA. These two areas like sensors of USA upon summer effects on COVID-19 PANDEMIC. Puerto Rico new infection peaked on April 10 with 110 infections, yesterday down to 50. For April 13 to April 18, total 200 new infections, or average 40 new infections/day. Hawaii new infection peaked on March 31 with 30 infections, and now 21 new cases in April 18. For the past week, total new infections were 95. Therefore, USA tropic zone leads the way of ending COVID-19 Pandemic this summer.

From the standing point of COVID-19 vaccine, for anti-COVID-19 IgG has been used as diagnosis tools, with more than 90% been positive for anti-COVID-19 IgM/IgG post infection, inactive vaccines certainly would be an effective vaccine.

REMDESIVIR showed good clinical data (one arm of Phase III) in severe COVID-19 patients (113/125 total)(STAT News). Most patients were cured in a week. Only 2 deaths. The data was better than historical controls. More data is on the way. Chicago 大学新冠病人 共125例， 113重症， 经REMDESIVIR治疗，发热等症状消失，大多一周出院，仅两例死亡。 比历史对照好。

New York, the leading state in COVID-19 infection and have had days of new infections over 10000 per day, now reported 6300 new infections for yesterday, Monday, April 13, 2020. New York is still cold though warm up some. This drop was mainly due to that people have stayed home to control viral infection as the nation asked. Hopefully the trend will continue. Staying home, Summer will come in 22 days.  New Yorkers! Doctors and nurses!

Coronavirus new infections in US dropped to 23570 in April 13, SHOWING a turning point in US COVID-19 infection. It is a mixed effect of staying home in US and hot weather in several states(Florida, Georgia, South Carolina, California). World new cases were also dropped to 72778, showing a sign of turning point of COVID-19. Data of South America, Africa, other tropic nations indicate that when it is closer to summer, new infection number would drop even more. Summer is May 5, only 22 days left, please stay home to help control the pandemic and help yourself and your family.

According to China news （新华社）, inactive COVID-19 VACCINE has moved to clinical studies in China. 中国灭活新冠病毒疫苗获准上临床试验。

It was happenned in China that China’s overall death rate was 4%, but warm provinces were only 0.5%. Here we saw that the death rate in Miami is only 1.3% whereas the overall current death rate of USA is 4%.

It seems that heat has two effects on coronavirus:  1) limit infection, as have seen in South America, Africa, OTHER TROPIC NATIONS/AREAS; 2) reduce deaths, as seen in China warm provinces Guangdong, Fujian, Zhejiang, etc, and now in Miami, USA.

Although the new cases still high for US (522188 cases) and NY(180458 cases), Florida (18494 cases) is on turning points for new cases on Easter. Washington state (9608 cases) is also on turning points on Easter, mainly due to its staying home police. Florida has not asked people to stay home. Florida’s turning points are mainly due to hot days. California (20615 cases) is near its turning point for good staying home police and warm weather.

Happy Easter for showing first signs of state-wide control of coronavirus in Washington state, Florida, and Califonia. Summer would be protective for against coronavirus. The best is to have good staying home police plus summer that may end coronavirus. China controlled the virus by staying home and isolating infected. 华盛顿州， 弗罗里达， 加州新冠病毒新增病例拐点已现。
