WHO on the second wave of coronavirus

The coro­n­avirus pan­dem­ic con­tin­ues to wreak hav­oc on the world. Yes, many coun­tries are grad­u­al­ly com­ing out of quar­an­tine. How­ev­er, the World Health Orga­ni­za­tion is not yet advised to rejoice. On the con­trary, it is worth prepar­ing for a new wave of the epi­dem­ic in the fall of 2020.

New wave of coronavirus

Coro­n­avirus dis­ease caused by Sars-Cov­‑2 infec­tion is not ful­ly under­stood. There­fore, the like­li­hood of a sec­ond wave of the pan­dem­ic is very high. Espe­cial­ly in autumn.

The World Health Orga­ni­za­tion warns that virus­es are very active dur­ing the cold sea­son. Along with COVID-19, the flu will also return, so a per­son can catch both dis­eases, which will only exac­er­bate the recov­ery process.

Coronavirus and herd immunity

Experts call now to pre­pare for the sec­ond wave of COVID-19: buy ven­ti­la­tors and equip wards for inten­sive care. The only way to end the pan­dem­ic they call a vac­cine.

In the Unit­ed States and oth­er coun­tries, they are already hard at work on the cre­ation of an antivi­ral drug. True, all devel­op­ments are at dif­fer­ent stages of test­ing.

Accord­ing to the direc­tor of the US Nation­al Insti­tute of Aller­gy and Infec­tious Dis­eases, Antho­ny Fau­ci, the effec­tive­ness and safe­ty of one of them will be proven by the first quar­ter of 2021. How­ev­er, many doc­tors con­sid­er the release of the vac­cine by Jan­u­ary too arro­gant goal:

“For this, every­thing must go incred­i­bly per­fect­ly,”

explained Dr. Lar­ry Corey, an expert in virol­o­gy, immunol­o­gy and vac­cine devel­op­ment.

The fact is that the drug must pass a series of safe­ty tests. Usu­al­ly tests are car­ried out on ani­mals. If the results are promis­ing, the vac­cine is test­ed in humans in three steps:

  • Step 1: A small group of peo­ple are giv­en the vac­cine to assess safe­ty and immune sys­tem response. If every­thing goes well, the doc­tors move on to the next step.
  • Stage 2. Num­ber In the sec­ond stage of the study, the num­ber of par­tic­i­pants increas­es (usu­al­ly up to a hun­dred). Here, sta­tis­tics are already being col­lect­ed on the impact of the vac­cine on dif­fer­ent groups of peo­ple depend­ing on age and health. The study includ­ed peo­ple whose char­ac­ter­is­tics matched those for whom the new vac­cine was cre­at­ed.
  • Step 3: The effec­tive­ness and safe­ty of the vac­cine is test­ed on thou­sands or tens of thou­sands of peo­ple. A sig­nif­i­cant­ly larg­er num­ber of par­tic­i­pants at this stage helps researchers learn about pos­si­ble rare side effects of the vac­cine.
Is the coronavirus transmitted by a mosquito bite?

The sto­ry goes that hasti­ly devel­oped and released vac­cines do not lead to any­thing good. They can only aggra­vate the dis­ease. There­fore, it remains to wait until the sci­en­tists con­duct all the tests. In the mean­time, let’s con­tin­ue to take pre­cau­tions against COVID-19.

It should be not­ed that 27,856 cas­es of coro­n­avirus dis­ease have already been record­ed in Ukraine. Recent­ly, the num­ber of infect­ed per day has been falling, which can­not but rejoice. As of June 9, 394 new infec­tions have been detect­ed in the last 24 hours.
